Figure 2. Basic Rigid Pavement Structure. Surface Course. The surface course is the layer in contact with traffic loads and is made of PCC. It provides characteristics such as friction (see Figure 3), smoothness, noise control and drainage.In addition, it serves as a waterproofing layer to the underlying base, subbase and subgrade.

Diamond grinding of pavement - Wikipedia

A multi-state study on noise and texture on PCC pavements concluded that longitudinal texture concrete pavements are among the quietest pavements for interior and exterior noise. Diamond grinding can also remove faults by leveling the pavement surface, thus eliminating the thumping and slapping sound created by faulted joints.
