Chaque nouvelle route debute parla construction du sol et de la roche<\/h2>\n

La nature ne fournit pas toujours les conditions de terrain id\u00e9ales, qu’il s’agisse de projets de g\u00e9nie civil ou de construction. Souvent, le sol existant n\u00e9cessite un traitement pr\u00e9liminaire pour am\u00e9liorer sa capacit\u00e9 de support. Dans d’autres endroits, les formations rocheuses massives doivent \u00eatre nivel\u00e9es.<\/p>\n

Quelles m\u00e9thodes sont utilis\u00e9es pour poser les bases?<\/p>\n

Compactage du sol<\/h2>\n

\u00c9tant donn\u00e9 que le sol est souvent meuble et pas assez coh\u00e9sif, des travaux de terrassement sont n\u00e9cessaires avant que les couches de base, de liaison et de surface puissent \u00eatre pos\u00e9es. Le compactage est le processus le plus important dans les travaux de terrassement. Le but du compactage est de r\u00e9duire le volume de sol rempli d’air et d’eau. Cela donne au sol les propri\u00e9t\u00e9s souhait\u00e9es: il devient plus r\u00e9sistant aux contraintes impos\u00e9es par la circulation et le climat.

Compactage d’une couche de gravier en mode oscillation: cette m\u00e9thode douce de compactage dynamique n\u00e9cessite seulement quelques passes de rouleaux pour obtenir des degr\u00e9s de densit\u00e9 \u00e9lev\u00e9s.<\/p><\/div>\n

<\/h2>\n

Stabilisation du Sol<\/h2>\n

La construction de routes n\u00e9cessite une base stable. Comment am\u00e9liorer la nature du sol existant? Quels sont les agents liants utilis\u00e9s \u00e0 cette fin ?
\n[one_third_first]<\/p>\n

APour commencer, un agent liant comme la chaux ou le ciment est \u00e9tal\u00e9.<\/p><\/div>\n

[\/one_third_first][one_third]<\/p>\n

Le compactage avec les compacteurs \u00e0 tambour unique, comme ceux de la s\u00e9rie 3000 de HAMM, est la derni\u00e8re \u00e9tape de travail dans la stabilisation des sols.<\/p><\/div>\n

Les stabilisateurs de sol stabilisent la fondation en m\u00e9langeant les composants de fa\u00e7on puissante et homog\u00e8ne.<\/p><\/div>\n

[\/one_third_last]<\/p>\n

 <\/p>\n

Les sols extr\u00eamement coh\u00e9sifs et humides ne conviennent pas pour le compactage par des rouleaux. Dans de tels cas, le sol existant doit \u00eatre stabilis\u00e9 d’abord pour am\u00e9liorer sa capacit\u00e9 de support et le pr\u00e9parer comme base appropri\u00e9e pour la structure de chauss\u00e9e sup\u00e9rieure.<\/p>\n

Op\u00e9rations de routage<\/h2>\n

Avant de commencer l’op\u00e9ration de construction de routes, les conditions pr\u00e9alables doivent \u00eatre \u00e9tablies. Lorsque vous conduisez des routes \u00e0 travers un terrain rocheux, des fraiseuses froides ou des mineurs de surface sont utilis\u00e9s pour pr\u00e9parer le sol pour la construction de routes – ou pour couper l’itin\u00e9raire, comme disent les professionnels.<\/p>\n

Road builders are confronted not only with subsoils that are excessively soft or Les constructeurs de routes sont confront\u00e9s non seulement aux sous-sols qui sont excessivement doux ou instables, mais aussi \u00e0 des bases extr\u00eamement difficiles – trop difficiles pour que les routes soient construites au niveau sp\u00e9cifi\u00e9 sans d’abord pr\u00e9parer le sol. Cette difficult\u00e9 se pose g\u00e9n\u00e9ralement lorsqu’une route doit \u00eatre construite sur un terrain montagneux ou dans d’autres r\u00e9gions o\u00f9 le sol est rocheux ou extr\u00eamement difficile[\/vc_column_text][\/vc_accordion_tab][vc_accordion_tab title=”New Road”][vc_column_text]<\/p>\n

Chaque route conduit \u00e0 une destination diff\u00e9rente<\/h2>\n

La construction d’une nouvelle route, que ce soit en asphalte ou en b\u00e9ton, n\u00e9cessite la production d’une structure de pavement parfaitement reli\u00e9e, en commen\u00e7ant par une couche de base stable et allant jusqu’\u00e0 une couche de surface nivel\u00e9e avec pr\u00e9cision.<\/p>\n

Quels sont les crit\u00e8res les plus importants \u00e0 prendre en consid\u00e9ration? Quelles m\u00e9thodes doivent \u00eatre appliqu\u00e9es? Quelles sont les machines utilis\u00e9es?<\/p>\n

Construction de couches de base<\/h2>\n

La couche de base d’une route jette les bases de la structure du trottoir sup\u00e9rieur. Elle doit offrir une excellente capacit\u00e9 d’appui, \u00eatre capable de r\u00e9sister \u00e0 une large gamme de conditions climatiques diff\u00e9rentes et rester fonctionnel pendant plusieurs d\u00e9cennies. Quels mat\u00e9riaux sont utilis\u00e9s pour la construction des couches de base? Quelles propri\u00e9t\u00e9s doivent-ils poss\u00e9der?<\/p>\n

[\/one_third_last]<\/p>\n

 <\/p>\n

La couche de base sert de fondement au pavage. Selon les contraintes \u00e0 pr\u00e9voir, la route comprend diff\u00e9rentes couches d’\u00e9paisseurs variees afin de r\u00e9sister aux conditions m\u00e9t\u00e9orologiques les plus diverses et rester operationnelle pendant plusieurs d\u00e9cennies<\/p>\n

Asphaltage<\/h2>\n

Le rev\u00eatement en asphalte n\u00e9cessite un degr\u00e9 exceptionnellement \u00e9lev\u00e9 de planification et de gestion logistiques m\u00e9ticuleuses. Il faut veiller \u00e0 ce que des quantit\u00e9s suffisantes de m\u00e9lange soient disponibles sur place tout le temps et que le m\u00e9lange ne refroidisse pas pr\u00e9matur\u00e9ment. Quels types de machines sont utilis\u00e9s pour le pavage d’asphalte? Quelle est la s\u00e9quence d’op\u00e9rations?<\/p>\n

Compactage D’Asphalte<\/h2>\n

Le compactage est la proc\u00e9dure finale dans la construction de routes, son objectif \u00e9tant de produire une texture de surface de haute qualit\u00e9. Quels aspects doivent \u00eatre pris en compte dans le compactage d’asphalte? Lors du compactage d’une route d’asphalte, quel impact aura la position ou la temp\u00e9rature ambiante de la route sur l’op\u00e9ration de compactage?
\n[one_third_first]<\/p>\n

Les rouleaux combin\u00e9s de HAMM – comme le rouleau de la s\u00e9rie HD pr\u00e9sent\u00e9s ici – offrent un m\u00e9lange id\u00e9al de compactage statique et dynamique.<\/p><\/div>\n

 <\/p>\n

Le compactage du pav\u00e9 d’asphalte devrait produire une surface uniforme avec la plus grande r\u00e9sistance possible au d\u00e9rapage et veiller \u00e0 ce que les couches individuelles d’asphalte soient solidement et durablement interconnect\u00e9es pour produire une stabilit\u00e9 \u00e9lev\u00e9e et une r\u00e9sistance \u00e0 l’usure, ainsi qu’une \u00e9tanch\u00e9it\u00e9 durable. Les rouleaux ou les compacteurs r\u00e9duisent le nombre de vides. Cela rend l’asphalte plus r\u00e9sistant aux contraintes et prolonge sa durabilit\u00e9.<\/p>\n

 <\/p>\n

Remplacer le trottoir est une proc\u00e9dure standard lors de la r\u00e9paration des routes. Le d\u00e9fi est de s’assurer que seules les couches endommag\u00e9es de la structure routi\u00e8re sont supprim\u00e9es et d’\u00e9viter les perturbations du trafic en m\u00eame temps. Dans ces conditions, le fraisage \u00e0 froid est la seule option viable pour de nombreux projets de construction.<\/p>\n

Broyage Fin<\/h2>\n

Le broyage fin est une alternative \u00e0 la r\u00e9habilitation compl\u00e8te qui est co\u00fbteuse et demande beaucoup de temps.

De nombreux pays investissent moins d’argent dans le maintien de leur r\u00e9seau routier malgr\u00e9 une augmentation des charges de trafic. Le r\u00e9sultat est une demande croissante pour des solutions rapides et \u00e9conomiquement efficaces qui sont capables de d’attenuer les tron\u00e7ons dangereux de la route. Le broyage fin est une de ces m\u00e9thodes et est utilis\u00e9 principalement lorsque les bosses et les ornieres, ou les surfaces glissantes posent un grave danger pour la s\u00e9curit\u00e9 routi\u00e8re.<\/p>\n

La s\u00e9curit\u00e9 routi\u00e8re est compromise lorsque la surface de la route devient glissante, lorsque les roues ont creus\u00e9 dans le trottoir ou lorsque la route est couverte de bosses et de d\u00e9formations. Le pavage de couches minces en application \u00e0 froid est une m\u00e9thode de plus en plus utilis\u00e9e pour restaurer les surfaces routi\u00e8res \u00e0 une bonne tenue et \u00e0 une r\u00e9sistance au d\u00e9rapage. Connu sous le nom de \u00abmicrosurfacing\u00bb dans de nombreux pays \u00e0 travers le monde, le rev\u00eatement de couches minces en application \u00e0 froid prolonge la dur\u00e9e de vie des routes asphalt\u00e9es endommag\u00e9es sans avoir \u00e0 remplacer l’ensemble du pav\u00e9 routier.<\/p>\n

Hot Recycling<\/h2>\n

Porous and deformed surface courses can be rehabilitated by hot recycling, a process which is exclusively applied in the form of a mobile construction site. An intact layer structure is essential here. Hot recycling improves all relevant properties of the surface and roadway profile, as well as the composition of aggregate fractions in the surface course.<\/p>\n

The surface course is heated up to 150 \u00b0C by a panel heating machine with gas-fired infrared heating panels so that the hot recycler can then scarify, remove, process and repave the softened asphalt. In this way, the road’s non-skid properties can be restored, water can run off again and ruts are eliminated. The potential savings are enormous.<\/p>\n

Cold Recycle In-Situ<\/h2>\n

Cold recycling in-situ is just the right technology when it comes to building a new road from old. It is mostly carried out as mobile roadworks. What are the advantages of \u201cin-situ\u201d cold recycling? How does the method work?<\/p>\n

 <\/p>\n

The sub-base of roads exposed to major stresses due to heavy goods traffic is often damaged. To remedy this damage, the complete road structure must be repaired. Cold recycling restores the roads’ stability.<\/p>\n

The difference between “in plant” and “in situ” cold recycling is that, in the latter case, the entire process takes place in a single operation. This is what happens: special cold recyclers granulate the defective layers – usually the surface and binder course, as well as part of the base course – mix the reclaimed asphalt pavement with fresh binder and replace it immediately. The advantages of this method are short construction times and high cost efficiency.<\/p>\n

Cold Recycling In-plant<\/h2>\n

When cold recycling road pavements, contractors can choose between processing the milled material \u201cin-situ\u201d, meaning on the job site, or \u201cin-plant\u201d, meaning in a cold mixing plant. Their decision is influenced, however, not only by the damage patterns of the road to be repaired. What are the advantages offered by \u201cin-plant\u201d cold recycling? How does it work? What kinds of damage patterns can cold recycling \u201cin-plant\u201d be used for?<\/p>\n

 <\/p>\n

One speaks of cold recycling \u201cin-plant\u201d when the reclaimed asphalt material of roads in need of rehabilitation is recycled in a nearby mixing plant, transported back to the job site, and then placed again by road pavers. The method is often used with roads that are exposed to high loads by heavy traffic, and with damages extending all the way into the pavement subgrade, but where site conditions do not allow the operation of an \u201cin-situ\u201d cold recycling train.[\/vc_column_text][\/vc_accordion_tab][vc_accordion_tab title=”Materials Mining”][vc_column_text]<\/p>\n

Surface Mining: Selective mining of pay minerals<\/h2>\n

Deposit material and mineral raw material are used for a whole variety of purposes, as a basis for construction or as a source of energy. But how are they mined? Which methods allow rock of every kind to be mined selectively and cost-efficiently?<\/p>\n

Drilling and blasting in mining, earthwork and rock operations are, quite simply, no longer \u201cstate of the art\u201d. Surface mining offers a far more economically efficient and environmentally friendly solution, as it is capable of cutting, crushing and loading rock in one single working pass.<\/p>\n

[one_third_first]<\/a>[\/one_third_first][one_third][\/one_third][one_third_last][\/one_third_last]<\/p>\n

 <\/p>\n

Surface Mining: Direct Loading<\/h2>\n

One of the most important features of the WIRTGEN Surface Miners is their ability to load the cut material directly onto trucks. WIRTGEN Surface Miners are designed for front loading or rear loading, depending on the model concerned.<\/p>\n

Front loading<\/h3>\n

On the front-loading 2200 SM, the discharge belt is mounted at the front of the machine. It can be slewed to either side and the discharge height adjusted as required. Depending on the size of the truck, these machines load the trucks either from the rear or from the side. The operator of the Surface Miner has a clear view of the truck.<\/p>\n

Rear loading<\/h3>\n

Other models, such as the 2500 SM and 4200 SM, are rear loaders, their discharge conveyor being mounted at the rear of the machine. The conveyor can be slewed about 90 degrees to either side and the discharge height adjusted as required. The operator of the Surface Miner can swivel his seat to the right or left to ensure that he has a clear view of the truck.<\/p>\n

 <\/p>\n

Gently loading trucks with small-sized material<\/h3>\n

In all cases, the fine grained material cut by the WIRTGEN Surface Miner ensures that the truck body is loaded uniformly, continuously and completely. These loading characteristics allow the truck size to be selected as required. Trucks with aluminium bodies and increased payload can also be used under certain circumstances, for example.<\/p>\n

Advantages<\/h3>\n

\n
• No material re-handling<\/li>\n
• Direct loading onto trucks is usually the most economical method if the material is to be transported over distances of more than approx. 500 m.<\/li>\n<\/ul>\n

  Surface Mining: Windrowing<\/h2>\n

  When working in windrowing mode, the cut material is deposited directly behind the machine without using the conveyor. This makes the cutting process independent of any loading processes (onto trucks). However, the material must subsequently be re-handled by a front loader.<\/p>\n

  In many cases, the higher productivity achieved by windrowing as compared with direct loading balances out the additional costs incurred for renewed handling of the material (e.g. by wheeled loaders).<\/p>\n

  Moreover, this method does not give rise to any belt wear and does not incur operating costs for the conveyor system.<\/p>\n

  [one_third_first]<\/a>[\/one_third_first][one_third]<\/a>[\/one_third][one_third_last]<\/a>[\/one_third_last][one_third_first]<\/a>[\/one_third_first][one_third]<\/a>[\/one_third][one_third_last][\/one_third_last]<\/p>\n

  <\/h3>\n

  Your advantages:<\/h3>\n

  \n
  • No time lost waiting for trucks<\/li>\n
  • No belt wear \/ higher availability<\/li>\n
  • Higher production output than when loading with conveyors<\/li>\n
  • Larger lump sizes<\/li>\n
  • Greater selectivity when working steep and inclined seams<\/li>\n
  • Most economical method for transport distances of less than approx. 150 m when handled by wheeled loaders and approx. 500 m in scraper operation<\/li>\n<\/ul>\n

    Surface Mining: Depositing the Material Laterally<\/h2>\n

    Sidecasting the material means that a stockpile is produced by dumping the material from several cuts on a pile via the belt. Depending on the slewing angle of the conveyor belt, material from 3 to 5 adjacent cuts can be piled up. Depending on the height of the resultant pile, the material can easily be picked up again by a front loader.<\/p>\n

    [one_third_first]<\/a>[\/one_third_first][one_third]<\/a>[\/one_third][one_third_last]<\/a>[\/one_third_last][one_third_first]<\/a>[\/one_third_first][one_third]<\/a>[\/one_third][one_third_last]<\/a>[\/one_third_last]<\/p>\n

    <\/h3>\n

    Advantages<\/h3>\n

    \n
    • Material can be mixed as it is mined<\/li>\n
    • Stockpiling in the mine<\/li>\n
    • No time lost waiting for trucks<\/li>\n
    • Independent operation<\/li>\n<\/ul>\n

      The innovative technology cuts expenses for machines and personnel and saves a considerable amount of time when compared to conventional methods. At the same time, it produces even, stable surfaces and embankments, and permits the selective mining of individual rock layers. And that\u2019s not all: Surface mining is a low-dust, low-noise method that causes no damaging vibrations and therefore permits effective mining of useful minerals close to residential areas or roads.<\/p>\n

      Cutting costs, boosting product quality and efficiency<\/h2>\n

      The mined and crushed material is so small that it can be processed profitably, requiring minimum subsequent treatment. Mining bauxite, phosphate, kimberlite or salt has become increasingly profitable and the surface miner can even mine hard limestone or granite with unconfined compressive strengths of up to 260 MPa without blasting.[\/vc_column_text][\/vc_accordion_tab][vc_accordion_tab title=”Materials Processing”][vc_column_text]<\/p>\n

      Economically efficient processing of natural stone and recycling materials<\/h2>\n

      Natural crushed stone and recycled materials in graded grain sizes are used as standard aggregate for concrete, as well as for base, binder and surface courses in road and building construction. But how are large chunks of rock converted into aggregate of defined size?
      \nCrushers are on the move<\/p>\n

      Versatility and flexibility in application are the major trump cards that mobile crushers play in comparison to stationary crushing plants. What are mobile crushers used for? What are the differences between the various crushing techniques? What about the hardness of the rock to be processed?<\/p>\n

      Mobile crushers are used in quarries, in mining, on job sites, and in the recycling industry. The robust plants mounted on crawler tracks are capable of processing both rock and recycling material, producing mineral aggregate and recycled building materials respectively for the construction industry.<\/p>\n

      [one_third_first][\/one_third_first][one_third][\/one_third][one_third_last][\/one_third_last]<\/p>\n

       <\/p>\n

      When processing natural stone or recycling material like demolition waste, concrete, asphalt, incineration ash or steel slag, an excavator or wheel loader feeds the material into the mobile crusher. Then then produced material is used for road construction or other, similar applications.<\/p>\n

      Processing of Natural Stone<\/h2>\n

      When processing natural rock, larger rocks are broken up into defined grain sizes in a multi-stage crushing and screening process. If the rock is processed in mobile plants, excavators transfer the blasted rock to crushers which are usually located directly alongside the quarry wall.<\/p>\n

      [\/one_third_first][one_third][\/one_third][one_third_last][\/one_third_last]<\/p>\n

       <\/p>\n

      The crushed stone is then either transferred directly to the next processing stage on conveyor belts or removed by trucks. Alternatively, the broken material can also be removed by heavy-duty trucks. Excavators or wheeled loaders load the rock onto trucks at the quarry wall for transport to the stationary processing plan.<\/p>\n

      Processing of Recycling Material<\/h2>\n

      In addition to reinforced concrete, asphalt and bricks, rubble and mixed construction wastes are separated into their useful components by mobile crushers or stationary crushing and sorting machines.<\/p>\n

      [one_third_first][\/one_third_first][one_third][\/one_third][one_third_last][\/one_third_last]<\/p>\n

       <\/p>\n

      A combined process of crushing, screening and separating metal is an efficient means of processing material to be recycled. To obtain an end-product of even higher quality, further process steps can be added, such as washing, eliminating such light materials as plastics and paper with the aid of air classification, and additional electromagnetic metal separation.<\/p>\n

      Different crushing techniques<\/h2>\n

      Crushing techniques distinguish between pressure crushing and impact crushing. Jaw crushers or cone crushers use the so-called pressure crushing technique where material is reduced in size mainly by high pressure between slow-moving wear parts. Impact crushers use the so-called impact crushing technique, in which the rock is accelerated by a massive fast-moving rotor and reduced in size by impacting against breaker walls. Jaw crushers are widely used for crushing medium-hard to hard rock, and are mostly used as primary crushers. Impact crushers work as both primary and secondary crushers for processing soft to medium-hard rock, producing larger quantities of fines. Cone crushers are used predominantly as secondary crushers for hard rock.[\/vc_column_text][\/vc_accordion_tab][vc_accordion_tab title=”Asphalt Production”][vc_column_text]<\/p>\n

      Asphalt production: the secret is in the mixing<\/h2>\n

      A thermal mixing process is required to produce asphalt from aggregate and bitumen for road construction and an asphalt mixing plant is essential here. Whether road-mobile, transportable or stationary \u2013 every mixture is a winner with tailor-made solutions by BENNINGHOVEN, the specialist for asphalt mixing plants.<\/p>\n

      [one_third_first][\/one_third_first][one_third][\/one_third][one_third_last][\/one_third_last]<\/p>\n

       <\/p>\n

      Production process<\/h2>\n

      We generally differentiate between two types of processes in asphalt production: continuous production and discontinuous or batch production.<\/p>\n

      Continuous Production<\/h2>\n

      In continuous production, there is no interruption to the mixing process. The individual components are continuously added to the mixing process. This process is particularly suited to large building projects requiring an aggregate or recipe that does not vary.<\/p>\n

      [one_third_first]<\/p>\n

      

      Mobile cold recycling mixing plants are equipped with a twin-shaft continuous compulsory mixer. The mixing plant can operate non-stop, thus continuously producing cold mix.<\/p><\/div>\n

      [\/one_third_first][one_third][\/one_third][one_third_last][\/one_third_last]<\/p>\n

      Discontinuous \/ Batch Production<\/h2>\n

      In batch production, the components of the asphalt mixture are first weighed before being mixed in batches in an asphalt mixer according to a specific recipe. This process is more flexible as the recipe for the mixture can be changed for each batch. What is more, a greater mixing quality can be achieved due to the more precise quantities added and adapted mixing cycles.<\/p>\n

      [one_third_first]<\/p>\n

      

      A quick change of recipe – necessary to react to changing demands – is only possible in discontinuous or batch production. This makes asphalt mixing plants flexible for any purpose.<\/p><\/div>\n

      [\/one_third_first][one_third][\/one_third][one_third_last][\/one_third_last]<\/p>\n

       <\/p>\n

      In Europe, the batch production process is the most widespread type of asphalt production.<\/p>\n

      The right type of asphalt mixing plant for the intended purpose<\/h2>\n

      While road-mobile and semi-mobile plants are usually used in areas with a less-developed infrastructure, high-performance stationary plants are normally popular in conurbations. BENNINGHOVEN provides flexible solutions for reliable and economic use and each BENNINGHOVEN plant is suitable for the production of both roller-compacted and mastic asphalt.<\/p>\n

      Stationary Asphalt Mixing Plant<\/h2>\n

      High-performance, stationary plants are more commonly used in conurbations. They are usually positioned at an easily accessible location, allowing for delivery to as large an area as possible while keeping delivery routes to building sites short. They are found, for example, close to motorway exits or in industrial estates in large cities. Some stationary asphalt mixing plants are located directly at mineral deposit sites such as quarries in order to minimize the cost of mineral aggregate deliveries. This type of plant requires a concrete foundation.<\/p>\n

      [one_third_first]<\/p>\n

      

      A stationary asphalt mixing plant is constructed from robust container units. Gangways and wide stairways around the plant allow for easy access and maintenance.<\/p><\/div>\n

      Transportable Asphalt Mixing Plants<\/h2>\n

      Transportable or semi-mobile plants are suitable for job sites which will only be operating for a specific period of time. They are generally acquired with the option of moving the plant to a different location, if required. This type of plant can be fitted with a fixed concrete foundation or a mobile steel foundation.<\/p>\n

      Road-mobile plants are suitable for job sites which will only be operating for a specific period of time. This plant is moved together with the mobile roadworks from one works section to the next. At the assembly site, the road-mobile asphalt mixing plant only needs a space that can be accessed by a truck for its foundation.<\/p>\n
