INVESTIGATION OF SYNTHETIC RESINS AND SYNTHETIC RESIN PAVEMENT PROPERTIES

THE OBJECT OF THIS INVESTIGATION WAS TO COMPARE THE PHYSICAL PROPERTIES OF SYNTHETIC RESINS WITH ASPHALT CEMENTS, THE PROPERTIES OF PAVING MIXTURES INCORPORATING THESE MATERIALS AND TO DETERMINE THE DURABILITY AND PERFORMANCE OF PAVEMENTS USING SYNTHETIC RESIN AS A BINDER. IN ONE SERIES OF TESTS, LABORATORY MIXTURES WERE INVESTIGATED FOR DENSITY, VOIDS, STABILITY, FLOW VALUE, BINDER ABSORPTION AND OPTIMUM BINDER CONTENT. TWO SOURCES OF AGGREGATE WERE STUDIED. IT WAS FOUND THAT OPTIMUM BINDER CONTENTS WERE THE SAME FOR SYNTHETIC RESIN AND ASPHALT CEMENT. HIGHER DENSITIES AND LOWER AID VOID CONTENTS WERE NOTED FOR THE SYNTHETIC RESIN MIXTURES. APPROXIMATELY 20 PERCENT GREATER MARSHALL STABILITIES WERE OBTAINED WITH THE SYNTHETIC RESIN MIXTURES OVER THE ASPHALT CEMENT MIXTURES. IN ANOTHER SERIES OF COMPARATIVE TESTS THE MIXTURES CONTAINING ASPHALT CEMENT AS THE BINDER HAS SLIGHTLY HIGHER MARSHALL STABILITIES THAN DID MIXTURES USING ANOTHER SOURCE OF SYNTHETIC RESIN. THE EFFECT OF VARYING TEST TEMPERATURES ON STABILITY VALUES SHOWED THAT FOR BOTH SYNTHETIC RESIN AND ASPHALT CEMENT MIXTURES STABILITIES INCREASED WITH DECREASING TEST TEMPERATURE AND THAT SYNTHETIC RESIN MIXTURES WERE MUCH MORE SUSCEPTIBLE TO TEMPERATURE THAN THE ASPHALT CEMENT. ON THE BASIS OF A LIMITED FREEZE-THAW DURABILITY STUDY IT WAS FOUND THAT MIXTURES WITH THE SYNTHETIC RESIN BINDERS HAD BETTER RESISTANCE TO DETERIORATION BY FREEZE-THAW ACTION THAN MIXTURES WITH ASPHALT CEMENT AS THE BINDER. TO IMPROVE THE QUALITY OF ASPHALT CEMENT 5-10 PERCENT OF AN ASPHALT-RESIN ADDITIVE WAS ADDED TO REGULAR ASPHALT. THE ADDITIVE PRODUCED A MARKED IMPROVEMENT IN THE DUCTILITY AND PERCENT RETAINED PENETRATION AFTER BEING SUBJECTED TO ELEVATED TEMPERATURE. THREE RESURFACING TEST PROJECTS WERE INSTALLED IN PENNSYLVANIA USING 3/8-INCH MAXIMUM SIZE AGGREGATE AND SYNTHETIC RESIN BINDER. AFTER THREE YEARS, THESE PAVEMENTS ARE PERFORMING SATISFACTORILY. THE AUTHOR CONCLUDES THAT SYNTHETIC RESINS ARE SATISFACTORY PAVING MATERIALS AND COMPARE FAVORABLY WITH ASPHALT CEMENT. /BPR/
