Back to: "P"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.
