An Extensive Range of World-Class Road Construction Equipment for Sale
There can be few of us who have not, at some time, paused to stare in awe at some aspect of the gargantuan task of constructing one of the major highways that now criss-cross the nation to connect its nine provinces. However, only those who have actually worked on such a project are likely to have an in-depth knowledge of the many complex processes that the task entails, or of the wide variety of specialised road construction equipment that is designed to perform these processes and that is offered for sale around the country and in many other nations on the African continent.
The engineers who undertake such tasks perform initial surveys to establish the control lines that provide the reference points that will serve to guide the construction crew. The next step will be to clear the proposed route and bordering areas of vegetation. Should it be necessary to install underground utilities, such as water or sewage mains, along with electrical conduits if a section may need to be illuminated, only when these preliminaries are completed, can the crew begin the surface work.
If a highway is to provide the lengthy and safe service that justifies its high cost, it must be built upon a sufficiently stable foundation. The process varies according to the nature of the terrain, which can be anything from loose soil, which will need to be compacted, through damp regions where binding agents such as lime and cement may be needed as stabilisers, to rocky terrain that must be levelled using surface miners or cold milling machines that are just two items of road construction equipment among the many others for sale.
Once the original rough ground has been compacted and stabilised, the next step will be to construct the base layers. Once again, there are specialises machines to introduce a gravel layer and compact it or to add metered quantities of cement slurry and then to level it. With the base layers in position and set firmly, it is time for the paving layer and the machinery required will differ according to whether the project calls for an asphalt or a concrete surface.
The use of asphalt calls for particular precise logistics, as it is crucial to ensure there is sufficient of the mix to complete the planned segment and that it is not allowed to cool. A typical machine will be able to handle a paving width of up to 16 m, depositing the mix at a rate of 1 600 tonnes in a single hour, after which a variety of rollers may be used to develop a thoroughly sealed, skid-resistant, and durable driving surface.
Where the projected loads are expected to be consistently heavy, concrete is the paving material of choice. Concrete requires its own range of road construction equipment which, like all of the other machinery mentioned, is also available for sale from Kanu Equipment. The range includes slipform pavers, electrical vibrators, and smoothers, to name just a few of the items supplied and meticulously maintained through the company’s extensive network.
