Title:

Installation Report on Porous Friction Course Hot Plant Mix
Authors:
G. W. Maupin, Jr.
Year: 1972
VTRC No.: 72-R11
Abstract: An investigation was initiated in the spring of 1972 to develop surface mixes with high skid resistance for use at special locations. The porous friction course will hopefully provide high skid coefficients where water drainage and hydroplaning may be problems. The porous friction course has sufficient voids and channels to allow water to drain to the bottom of the layer and out to the shoulder.
