SKID RESISTANCE OF DENSE-GRADED ASPHALT CONCRETE

Descriptions and skid results are given for Virginia's sand mix, plant mix seal, dense-graded mix, and urban mix. Although sand mix has provided good skid resistance under most circumstances, problems are encountered in areas of water buildup. Durability problems also are encountered under high-speed truck traffic. Plant-mix seal is extremely useful in situations where water buildup is a problem, but it has possible durability and service-life disadvantages. Experience has shown that dense-graded mixes are durable, and skid test data indicate that good skid resistance is provided at high speeds under heavy water conditions. The urban mix described (a special, dense-graded mix) contains coarse, non-polishing aggregate and fine, polishing aggregate. It has good durability and skid resistance. Of the mixes discussed, the dense-graded mix is the best for skid resistance and economy.
