SYNTHETIC AGGREGATES FOR ASPHALT CONCRETE MIXES

THE FINDINGS REPORTED HEREIN FURNISH THE HIGHWAY CONSTRUCTION INDUSTRY WITH BASIC DESIGN CRITERIA FOR THE INCLUSION OF SYNTHETIC AGGREGATES IN ASPHALTIC CONCRETE MIXES AS WELL AS LABORATORY AND FIELD TEST DATA SUPPORTING FAVORABLE PERFORMANCE OF THIS NEW AGGREGATE USED AS A SUBSTITUTE FOR NATURAL AGGREGATES. THIS REPORT ALSO POINTS UP A VERY MEANINGFUL CHARACTERISTIC OF LIGHTWEIGHT SYNTHETIC AGGREGATES, NAMELY, THE FRICTION TEXTURED CHARACTERISTICS ARE SUPERIOR TO NATURAL AGGREGATES. EXTENSIVE FIELD DATA PRESENT AMPLE PROOF THAT LIGHTWEIGHT AGGREGATE USED AS THE COARSE AGGREGATE FRACTION IN BITUMINOUS MIXES PROVIDES LONG LASTING HIGH SKID RESISTANCE. /AUTHOR/
