Abstract

Provision of skid-resistant pavement surfaces adequate to meet the needs of the motoring public on a wide range of facilities requires a systematic approach. The system employed should have reliable testing procedures to determine friction, criteria to determine corrective action and predictable specifications for surfacing materials to obtain the desired performance. The Pennsylvania Department of Transportation has adopted procedures based on a long history of research and development to obtain an economical and predictable skid resistant performance for pavements. The testing program, corretction criteria and specification development using a Skid Resistance Level (SRL) criterion for aggregates is described.
