An Inventory of the Skid Resistance of Idaho Highways

A locked wheel trailer meeting the specifications of ASTM E-274-65 was purchased in October 1970. During the summer and fall an inventory of the skid resistance of all highways on the Idaho State highway system was made. Skid numbers (coefficient of friction x 100) ranged in value from 10 to 78 with an average of 57. Testing followed the procedures established by the American Society for Testing and Materials (ASTM). Tests were made on the average of every two lane miles, testing more frequently in non-uniform sections and less frequently in long, uniform sections. A program for maintaining the inventory current will be pursued by testing new pavements as they are completed and retesting pavements at some designated interval of time.
