COLD WEATHER PAVING-TEMPERATURE-DENSITY

A COLD WEATHER PAVING EXPERIMENT WAS CONDUCTED IN WOODBRIDGE, NEW JERSEY, DURING JANUARY 1968 WITH THE COOPERATION OF THE ASPHALT INSTITUTE. THE DEMAND FOR HOT-MIX ASPHALT IN THE AREA FAR EXCEEDED THE PRODUCTION CAPABILITIES SO IN ORDER TO PERMIT COLD WEATHER PAVING, IT WAS NECESSARY TO DETERMINE WHAT CHANGES IN THE SPECIFICATIONS WERE NEEDED TO OBTAIN THE DESIRED RESULTS. THE RELATIONSHIP WAS STUDIED BETWEEN THE TEMPERATURE OF THE MIX AT THE TIME OF PLACEMENT AND THE DENSITY OBTAINED IN TERMS OF PER CENT VOIDS. THIS RELATIONSHIP WAS COMPARED WITH THAT WHICH HAD BEEN PREVIOUSLY DETERMINED FOR HOT WEATHER PAVING. WOODBRIDGE REQUIRED CERTAIN STANDARDS AND PROCEDURES FOR FULL DEPTH PAVEMENT CONSTRUCTION AND THESE STANDARDS AND PROCEDURES WERE FOLLOWED FOR ALL THE RESEARCH AND EXPERIMENTAL WORK. THE FOLLOWING CONCLUSIONS WERE REACHED: (1) THE TEMPERATURE-DENSITY RELATIONSHIP DURING THE ROLLING PROCEDURE IS THE SAME FOR BOTH WARM WEATHER AND COLD WEATHER CONSTRUCTION, (2) WITH PROPER ENFORCEMENT OF THE DESIRED MIX TEMPERATURE AT THE TIME OF PLACEMENT AND PROPER ROLLING PROCEDURE, DEEP LIFTS OF HOT PLANT MIX ASPHALT BASE CAN BE COMPACTED TO THE DESIRED DENSITY IN COLD WEATHER, (3) WHEN A GOOD SYSTEM OF QUALITY CONTROL, INSPECTION AND PERFORMANCE IS REQUIRED , THE PROBABILITY OF SUCCESS WHEN PAVING IN COLD WEATHER IS THE SAME AS THE PROBABILITY OF SUCCESS IN WARM WEATHER, AND (4) DEEP LIFT ASPHALT BASE CONSTRUCTION MAY BE EXTENDED INTO THE COLD WEATHER AS LONG AS IT IS PRACTICAL AND ECONOMICAL TO PROPERLY PREPARE THE SUBGRADE, THE MINIMUM COMPACTED THICKNESS IS NOT LESS THAN FOUR INCHES, AND THE TEMPERATURE OF THE MIX WHEN LAID IS NOT LESS THAN 275F. THE APPENDICES PRESENT THE MIX DESIGN DATA, PLAN OF TEST SECTION, CORE SCHEDULE, RECORDED TEMPERATURES, AND CORE AIR VOIDS.
