NEW JERSEY COMPOSITE PAVEMENT PROJECT

THIS PAPER REPORTS ON THE 8-YEAR PERFORMANCE OF A 1,500-FT SECTION OF COMPOSITE PAVEMENT CONSTRUCTED IN 1963 ON NJ-3, A MAJOR ROUTE CARRYING APPROXIMATELY 88,780 VEHICLES DAILY: OF THOSE VEHICLES, 14.6 PERCENT ARE TRUCKS. THE PAVEMENT CONSISTED OF A 5-COMPONENT SYSTEM INVOLVING A 6-IN. CRUSHED STONE SUBBASE, AN 8-IN. PLAIN CONCRETE BASE, A 3-IN. LAYER OF DENSELY GRADED CRUSHED STONE, A 5-IN. LAYER OF DRY- BOUND MACADAM, AND A 3.5-IN. SURFACE OF BITUMINOUS CONCRETE. THE PAVEMENT WAS DESIGNED TO PROVIDE LONG-TERM SERVICEABILITY AND TO REQUIRE AN ABSOLUTE MINIMUM OF MAINTENANCE, DESPITE THE UNSTABLE NATURE OF THE TERRAIN AND VERY HEAVY TRAFFIC, COST WAS ABOUT 15 PERCENT HIGHER THAN THAT OF NEW JERSEY'S STANDARD DESIGN OF REINFORCED CONCRETE PAVEMENT BUT IS EXPECTED TO BE OFFSET BY THE ESTIMATED 23 PERCENT LONGER SERVICE LIFE. PERFORMANCE DATA FROM BENKELMAN BEAM DEFLECTIONS, RUT DEPTHS, ROUGHOMETER MEASUREMENTS, CROSS-SECTIONAL AND PROFILE MEASUREMENTS, AND CONDITION SURVEYS SHOW THAT THE COMPOSITE PAVEMENT HAS PERFORMED AS DESIGNED WITH MINIMAL MAINTENANCE.
