THE PURPOSE OF THIS REPORT IS TO PRESENT AN EVALUATION OF PERFORMANCE OVER A 3-YR PERIOD OF AN EXPERIMENTAL ASPHALT- CONCRETE OVERLAY PAVEMENT CONSTRUCTED ON SHELL AVENUE IN CONTRA COSTA COUNTY, CALIFORNIA. THE OVERLAY PAVEMENT WAS CONSTRUCTED ON AN EXISTING PAVEMENT EXHIBITING FAIRLY LARGE DEFLECTIONS UNDER A 15,000-LB AXLE LOAD, AND SUBJECTED TO A LARGE PROPORTION OF TRUCK TRAFFIC IN TERMS OF THE AVERAGE DAILY TRAFFIC APPLIED TO THE HIGHWAY. BECAUSE OF THE EXISTING CONDITIONS, IT WAS PLANNED THAT THE TEST PAVEMENT SHOULD PROVIDE INFORMATION ON THE RESISTANCE TO DEFORMATION (STABILITY) AND FATIGUE RESISTANCE OF HEAVY-DUTY MIXES USING CONVENTIONAL ASPHALT CONCRETE AND ASPHALT CONCRETE WITH ASBESTOS AS A SPECIAL MINERAL FILLER. THE TEST PAVEMENT IS APPROXIMATELY 3,200 FT LONG AND IS DIVIDED INTO 4 SECTIONS, 2 WITH MIXTURES CONTAINING ASBESTOS AND 2 CONTROL SECTIONS WITHOUT ASBESTOS. INSTRUMENTATION WAS INSTALLED IN THE PAVEMENT AT THE TIME OF CONSTRUCTION TO MEASURE DYNAMIC DEFLECTIONS, BENDING STRAIN, AND TEMPERATURE. THE REPORT IS CONCERNED WITH AN EVALUATION OF PERIODIC MEASUREMENTS OF DEFLECTION, STRAIN, AND TEMPERATURE; LABORATORY EVALUATION OF CORES, INCLUDING DENSITY, STABILITY AS MEASURED BY THE HVEEM STABILOMETER, AND VISCOSITY AT DIFFERENT LEVELS IN THE OVERLAY AS MEASURED BY THE SLIDING PLATE MICROVISCOMETER; SKID RESISTANCE AND ROAD ROUGHNESS MEASUREMENTS. FROM AN EVALUATION OF THE FIELD AND LABORATORY TESTS, TOGETHER WITH VISUAL INSPECTION OF THE PERFORMANCE OF THE ROAD, CONCLUSIONS ARE PRESENTED WITH REGARD TO THE ABILITY OF THE VARIOUS TEST PAVEMENTS TO PERFORM UNDER THE TRAFFIC IMPOSED AND WITHIN THE PARTICULAR ENVIRONMENT. /AUTHOR/ ENVIRONMENT. /AUTHOR/ IMPOSED AND WITHIN THE PARTICULAR ENVIRONMENT. /AUTHOR/
