CRUSHED GRAVEL COARSE AGGREGATE IN ASPHALT CONCRETE PAVEMENTS

THE FIELD PERFORMANCE OF A GROUP OF NEW YORK STATE ASPHALT CONCRETE PAVEMENTS CONSTRUCTED WITH CRUSHED GRAVEL COARSE AGGREGATE WAS COMPARED TO THAT OF A SIMILAR GROUP OF PAVEMENTS CONSTRUCTED WITH CRUSHED STONE. ALSO COMPARED WAS THE PERFORMANCE OF GRAVELS FROM THE ADIRONDACK HIGHLANDS WITH GRAVELS FROM THE SOUTHERN TIER. LABORATORY STUDIES WERE CONDUCTED ON CORES TAKEN FROM THE CRUSHED GRAVEL PAVEMENTS TO ASCERTAIN THE SIMILARITIES BETWEEN THEIR PHYSICAL PROPERTIES AND THOSE OF SELECTED GROUPS OF SAMPLES FROM CRUSHED STONE PAVEMENTS. SURVEYS WERE PERFORMED ON LOCAL GOVERNMENT PAVEMENTS IN NEW YORK AND ON PENNSYLVANIA STATE HIGHWAYS CONSTRUCTED WITH CRUSHED GRAVEL FROM NEW YORK STATE SOURCES. NEW YORK ASPHALT CONCRETE PAVEMENTS CONSTRUCTED WITH CRUSHED GRAVEL WERE FOUND (1) TO BE PERFORMING SIMILARLY TO CRUSHED STONE PAVEMENTS WITH RESPECT TO ROUGHNESS, RUTTING, AND CRACKING AND PATCHING (COMPONENTS OF THE PRESENT SERVICEABILITY INDEX OF PSI); (2found TO HAVE GOOD SKID RESISTANCE; AND (3) TO BE COMPARABLE TO A SELECTED GROUP OF CRUSHED STONE MIXES IN MARSHALL STABILITY. PAVEMENTS CONSTRUCTED WITH CRUSHED GRAVEL FROM SOURCES IN THE ADIRONDACK HIGHLANDS AND THE SOUTHERN TIER WERE FOUND TO BE PERFORMING SIMILARLY ON THE BASIS OF RESULTS OF THIS STUDY WERE USED IN DEVELOPING NEW STATE SPECIFICATIONS PERMITTING THE USE OF CRUSHED GRAVEL IN ASPHALT CONCRETE WHEN IT MEETS THE SAME QUALITY REQUIREMENTS AS CRUSHED STONE OR SLAG. /FHWA/
