Abstract:

WITH THE INCREASING EMPHASIS ON SAFETY IN HIGHWAY ENGINEERING, THE BUREAU OF PUBLIC ROADS, TOGETHER WITH THE STATE HIGHWAY DEPARTMENTS OF COLORADO, WYOMING, UTAH, AND NEW MEXICO, CONDUCTED A SKID RESISTANCE STUDY OF PAVEMENT SURFACES IN THE FOUR STATES. ALL TESTING WAS CONDUCTED WITH THE BUREAU OF PUBLIC ROADS SKID TRAILER FOLLOWING ASTM CRITERIA AND PROCEDURES. A TOTAL OF 979 TESTS WERE CONDUCTED ON A VARIETY OF SURFACE TYPES AND HIGHWAY SYSTEMS. DUE TO ITS OPEN-TEXTURED SURFACE, THE BITUMINOUS PLANT-MIX SEAL GAVE THE HIGHEST SKID-RESISTANCE COEFFICIENTS, FOLLOWED BY CHIP SEALS, ASPHALT CONCRETE AND CONCRETE. WITH CHIP SEALS, AS WITH ALL OTHER SURFACES, ADT AND AGE PROVED TO BE THE MOST INFLUENTIAL FACTORS GOVERNING THE SKID RESISTANCE OF PAVEMENTS. A BIG DIFFERENCE IN SKID RESISTANCE BETWEEN THE INSIDE AND OUTSIDE LANES ON FOUR-LANE ROADS WAS FREQUENTLY NOTICED THROUGHOUT THE FOUR STATES. IT WAS CONCLUDED THAT THE USE OF BITUMINOUS PLANT-MIX SEALS IS THE BEST MEANS NOW AVAILABLE FOR INSURING A HIGH-QUALITY SKID-RESISTANT SURFACE, NOT ONLY AS AN OVERLAY ON EXISTING SURFACES, BUT ALSO IN THE CONSTRUCTION OF NEW PAVEMENTS. THIS STUDY PROVED BENEFICIAL TO THE BUREAU OF PUBLIC ROADS, AND TO THE PARTICIPATING FOUR STATES. A WORKING KNOWLEDGE OF THE SKID RESISTANCE OF EXISTING ROADS IS, AND WILL CONTINUE TO BE, EXTREMELY HELPFUL TO HIGHWAY ENGINEERS. /AUTHOR/
