porous friction course
Definição1
The porous friction course consists of an open-graded, bituminous surface course composed of mineral aggregate and bituminous material, mixed in a central mixing plant, and placed on a prepared surface. This friction course is deliberately designed not only to improve the skid-resistance but to reduce aquaplaning incidence by providing a “honeycomb” material to ensure a quick drainage of water from the pavement surface direct to the underlying impervious asphalt.

Contexto
Drainage capability can, in addition, be enhanced by special surface treatments, such as grooving and porous friction course which drains water initially through voids of a specially treated wearing course.
