ASPHALT PAVING WORKSHOP - 2

THE EFFECT OF A SILICONE MIX ADDITIVE ON PAVEMENT COMPACTION IS DISCUSSED. A REVIEW WAS MADE OF STUDY RESULTS ON ASPHALT TREATED WITH DIFFERENT RATES OF SILICONE. COMMENTS WERE MADE ON THICK-LIFT PAVING PROCEDURES, PARTICULARLY AS TO PROPER TIRE PRESSURE FOR BREAK-DOWN AND ON CONTROL SPREAD OF LOOSE MIX TO SECURE UNIFORM MAT THICKNESS. THERE WERE SUGGESTIONS ON HOW TO GET RESURFACING OPERATIONS STARTED QUICKLY AFTER A RAIN. WEAR COST WAS EXPERIENCED TO RUN ABOUT DOUBLE WITH MIXES USING GRAVEL OR GRANITES, COMPARED WITH LIMESTONE OR CERTAIN EASILY FRACTURED TRAPROCKS. COMMENTS WERE MADE ON PRODUCTIVITY VS QUALITY, AND MIX HAULING AND COSTS. RECOMMENDATION WAS MADE THAT THE STABILITY TEST TEMPERATURE OF ASPHALT MIXES USED IN HIGHWAY COURSES BE LOWERED FROM 140 F TO 100 F.
