BEST TEMPERATURE TO MEASURE VISCOSITY FOR EVALUATION OF ASPHALT DURABILITY IN SERVICE

AN INVESTIGATION WAS CONDUCTED TO DETERMINE HOW THE DURABILITY OF ASPHALT CEMENTS IN SERVICE CAN BE IMPROVED. STUDIES WERE CONDUCTED CONCERNING THE HARDENING OF ASPHALT CEMENT DURING THE PREPARATION, LAYING AND COMPACTION OF HOT- MIX SURFACING MATERIALS AND THE HARDENING OF THE BINDER DURING SERVICE IN THE PAVEMENT. THE EXPERIMENTS YIELDED INFORMATION WHICH HELPS IN ESTABLISHING THE MOST SUITABLE TEMPERATURE TO USE FOR EVALUATING THE HARDENING OF ASPHALTS DURING SERVICE. IT IS COUCLUDED THAT THERE IS NO REASON FOR COMPLICATING THE TECHNICAL PROCEDURES AND INCREASING THE OPERATIONAL COST BY USING 60F INSTEAD OF THE 77F FOR THE DETERMINATION OF VISCOSITIES USED IN THE EVALUATION OF DURABILITY OF ASPHALT CEMENTS DURING SERVICE, IT IS RECOMMENDED THAT 77F BE USED AS THE TEMPERATURE MOST SUITABLE FOR EVALUATING THE HARDENING OF ASPHALT CEMENTS UNDER SERVICE CONDITIONS.
