NEWBURGH-HAMPDEN - AN EXPERIMENTAL PAVING PROJECT CONTAINING 13 COMBINATIONS OF FILLERS AND GRADES OF ASPHALT

THE DESIGN AND CONSTRUCTION IS DESCRIBED OF 13 BITUMINOUS CONCRETE TEST SECTIONS ON 8 MILES OF PAVEMENT AND OBSERVATION OF THESE OVER A PERIOD OF TIME. THE MAIN VARIABLES WERE THREE GRADES OF ASPHALT CEMENT AND FOUR TYPES OF MINERAL FILLER. AN ADDITIONAL SECTION CONTAINED A POLYMER BLENDED ASPHALT. SAMPLES OF MIXTURE WERE OBTAINED FROM CONSTRUCTION AND THE PAVEMENT WAS SAMPLED AT TWO SUBSEQUENT PERIODS. SAMPLES WERE TESTED FOR DENSITY AND HARDENING OF THE ASPHALT CEMENT. GENERALLY, THE MIXTURES DENSIFIED WITH TIME AND TRAFFIC ALTHOUGH IT WAS FOUND THAT DENSIFICATION CONTINUED DURING WINTER MONTHS WHICH WAS NOT EXPECTED. THE FILLER HAD INFLUENCE ON DENSIFICATION THAN DID THE ASPHALT GRADE. THE TRENDS FOR HARDENING OF THE ASPHALT WERE INCONCLUSIVE IN THAT MOST OF THE RESULTS SHOWED SOFTENING FOLLOWING CONSTRUCTION. VISUAL OBSERVATIONS INDICATED LITTLE DIFFERENCE IN THE PERFORMANCE OF THE MIXTURES DURING CONSTRUCTION AND AFTER FOUR YEARS OF SERVICE. /BPR/
