Abstract
Louisiana produces no naturally occurring skid resistant aggregate and, therefore, must import these aggregates at great expense. In an effort to extend the yield of these aggregates, a laboratory investigation was initiated to determine the feasibility of blending these aggregates with aggregates of less skid quality while maintaining good skid resistance. These evaluations were conducted by use of the Wessex Accelerated Polishing Machine and the British Portable Tester. Laboratory results indicate that certain blends of aggregates are feasible.
