Skid Resistance of Bituminous Surfaces
A drag force trailer with controlled braking of one wheel was used to measure the coefficient of friction of wet bituminous surfaces. Nearly all crushed stone aggregates used in the State were included in surfaces measured. A technique for measuring the skid resistance of bituminous surfaces constructed in the laboratory and subject to artificially induced traffic wear was tried but was not successful. Analysis of data indicated that a coefficient of friction above 0.32 could be assured if the aggregate retained on the 1/4 inch sieve for 1A mixes (bituminous concrete) or the aggregate retained on the 1/8 inch sieve for 1A-C and 2A mixes (sheet asphalts) contains more than 12 percent hard minerals either as impurities in softer aggregates or as individual stones. An acid leaching technique was used to determine the percentage of hard impurities in limestone and dolomite aggregate. (BPR Abstract)
