PERFORMANCE OF BITUMINOUS-MIX DESIGNS

REPORTS ARE MADE ON THE OBSERVED BEHAVIOR AND PERFORMANCE OF 14 SECTIONS, EACH 1,000 FEET LONG OF BITUMINOUS CONCRETE, AND VARIOUS TYPES OF BITUMINOUS SURFACE TREATMENT OVERLAY PAVEMENT ON OLD PORTLAND-CEMENT CONCRETE. THREE TYPES OF COARSE AGGREGATE WERE USED: CRUSHED GRANITE, CRUSHED GRAVEL (ABOUT 50 PERCENT CRUSHED PARTICLES) AND UNCRUSHED GRAVEL. APPROXIMATELY 550 SAMPLES WERE TAKEN FROM THE PLANT AND ROADWAY, DURING CONSTRUCTION AND AFTER THE PAVEMENT HAD BEEN IN SERVICE A YEAR, WITH THE LOCATION OF EVERY LOAD PLACED IN THE ROAD ACCURATLY IDENTIFIED IN ORDER TO DETERMINE THE UNIFORMITY OF THE PROPORTIONING AND MIXING OPERATIONS. ONE OF THE MOST IMPORTANT FACTORS IN THIS TEST IS THE DEGREE OF COMPACTION UTILIZED IN THE DESIGN PROCESS AND THE CORRELATION WITH THAT WHICH CAN BE OBTAINED IN THE FIELD. THE COMPACTIVE EFFORT IN THE LABORATORY IN THE PREPARATION OF TEST SPECIMENS SHOULD BE THE SAME AS, OR BEAR A KNOWN RELATION TO, THE FIELD COMPACTIVE EFFORT AND THE EFFECT OF TRAFFIC IN RELATION TO DENSITY AFTER ONE YEAR OF SERVICE. THE DATA SHOULD MAKE IT POSSIBLE TO DEVELOP SATISFACTORY CONTROL FOR FUTURE ASPHALT-PAVEMENT CONSTRUCTION FOR HEAVY-DUTY HIGHWAYS AND AID IN OBTAINING CORRELATION BETWEEN THE RESULTS OF MECHANICAL TESTS ON THE MATERIALS AND THEIR ROAD BEHAVIOR.
