MIX DESIGN CRITERIA FOR WEAR RESISTANT BITUMINOUS PAVEMENT SURFACES WITH DISCUSSION

THIS REPORT PRESENTS THE RESULTS OF A LABORATORY STUDY CARRIED OUT TO ESTABLISH MIX DESIGN CRITERIA FOR WEAR-RESISTANT BITUMINOUS MIXTURES. THE RELATIVE WEAR RESISTANCE OF VARIOUS TYPES OF PAVING MIXTURES WAS MEASURED BY A LABORATORY TEST RIG THAT CONSISTED OF 2 WHEELS DRIVEN BY A CENTRAL VERTICAL SHAFT SO THAT THEY TURNED FREELY ON A CIRCULAR RUNWAY MADE OF 12 JUXTAPOSED TRAPEZOIDAL TEST SPECIMENS. BITUMINOUS MIXTURES WEAR BY PULVERIZATION, CUTTING, AND ATTRITION, AND WEAR IS ACCELERATED BY FRAGMENTATION, LOOSENING, AND DISLODGMENT OF AGGREGATE PARTICLES. RATE OF WEAR IS LOWEST NEAR FREEZING TEMPERATURE AND INCREASES WITH INDREASING PLASTICITY OF THE MIX AT HIGHER TEMPERATURE OR WITH INCREASING STUD FORCE AND BRITTLENESS OF THE MIX AT LOWER TEMPERATURE. RATE OF WEAR GREATLY INCREASES WHEN THE PAVEMENT IS WET. FACTORS AFFECTING THE RESISTANCE TO WEAR WERE IDENTIFIED AND THEIR RELATIVE INFLUENCE ON WEAR DETERMINED. MIX DESIGN CRITERIA FOR WEAR-RESISTANT BITUMINOUS PAVEMENT SURFACES WERE ESTABLISHED, AND PERFORMANCE OF CONVENTIONAL AND SPECIAL BITUMINOUS MIXTURES ARE DISCUSSED.
