Science goes into every aspect of building a road to ensure it will last. The materials are tested at many points before the road is laid to make sure the materials will hold up to weathering and levels of traffic. There are many different materials used when building a road, many will depend on the traffic, but lab supply is critical to proper testing.
Road Material Selection: Factors & Engineering
Asphalt and aggregate (or composite) concrete are the strongest and therefore used for building roads that have high levels of traffic. Areas with low traffic and low speeds allow for materials like bituminous surface treatment or chip seal. For driveways and rural roads, gravel or road base (an aggregate of ground-up rock materials) may be used to keep the road from washing out and grooving too badly. These roads will need to be maintained to keep them functional, but the materials laid will help keep the road in better shape than if left-packed dirt.
Beyond the testing in the lab, the process of laying the roads is very specific and requires engineering to make sure there is proper drainage and degrees of incline. For high-traffic roads, there is more engineering that goes into building the road, as they need to make sure curves will be safe for the speeds. The roads also need to be prepped for asphalt or concrete so they will be smooth for the traffic and speeds, and so they will last.
