Concrete pavements (specifically, Portland cement concrete) are created using a mixture of Portland cement, gravel, sand, and water. The material is applied when it is a fresh grout and is worked by mechanical means (vibration) to compact the interior and allow the finer cement to remain in the upper layer to create a smoother and denser surface, free of crocodile skin (cracks that are produced by the shrinkage of the concrete). Water allows the mixture to combine at a molecular level in a process called hydration.

Concrete surfaces can be of the following three types depending on the treatment of the cracks:.

An advantage of concrete roads is that they are stronger and last longer than asphalt roads. They are also very easy to maintain, because once they wear out they can be easily repaired to regain their texture. The disadvantages are that they have a high initial cost, they are harsher for the driver, the cracking never stops and they are more difficult to repair if they suffer a fracture. Recent studies show that most of these roads are damaged due to the weight of the trucks. Repairs are often expensive and time-consuming.
