The application of a layer of asphalt on sand, a foundation or already applied road surface is done using a paving machine. In the case of very small works or at locations difficult to access with the machine, asphalt is laid manually. Immediately after application, road rollers ensure optimum compaction of the asphalt. When the asphalt has cooled, it can be used for traffic.
The base is a surface treatment (protective layer) consisting of one or more layers of crushed stone on a hardened surface. A distinction is made between a single-layer base, single-layer base with double gravel layer, and double-layer base.
Poured asphalt is a material that is extremely well suited among others to municipal and urban infrastructure work. Possible additional costs in installation are amply offset by its durability and advantages during execution. Poured asphalt certainly has advantages here due to its properties, its possibilities for colouring and its ability to be combined with other natural materials. Much expertise and experience with the product on the part of the processor is required to ensure the proper processing and application of poured asphalt.
