EVALUATION OF BITUMINOUS SURFACES USING FINER AGGREGATES

THIS INVESTIGATION IS BEING CONDUCTED TO EVALUATE THE PERFORMANCE, UNDER LOW TRAFFIC VOLUMES, OF BITUMINOUS SURFACES CONSTRUCTED WITH FINER AGGREGATES THAN THOSE PERMITTED UNDER MHD SPEC. 2331. PROJECTS WERE CONSTRUCTED ON LOW-TRAFFIC VOLUME ROADS IN KOOCHICHING, PINE AND WASECA COUNTIES IN 1969 AND 1970. THE PERFORMANCE OF THESE PROJECTS OVER THE FIRST YEAR OR TWO HAS BEEN SATISFACTORY. USE OF FINER AGGREGATES CAN RESULT IN SIGNIFICANT COST REDUCTION IN AREAS OF GRAVEL SCARCITY. IT IS INDICATED BY THE STUDY THAT FINER AGGREGATES OF GRADATION SUCH AS USED ON THESE PROJECTS CAN PROVIDE ADEQUATE SERVICE PERFORMANCE UNDER CONDITIONS OF LOW TRAFFIC DEMANDS. OBSERVATIONS WILL BE CONTINUED FOR FURTHER LONG-TERM EVALUATION. /FHWA/
