SOLID RUBBER TIRE ROLLER STUDY

THIS REPORT COMPARES THE EFFECTIVENESS OF A SOLID RUBBER TIRED ROLLER WITH THAT OF A CONVENTIONAL PNEUMATIC TIRED ROLLER IN COMPACTING BOTH BINDER AND WEARING COURSES OF ASPHALTIC CONCRETE PAVEMENTS AT CONSTANT CONTACT PRESSURE. RESULTS OF THE STUDY INDICATED THE FOLLOWING WITH REGARD TO THE BINDER COURSE: (1) BOTH ROLLERS ACHIEVED THE MINIMUM REQUIREMENT OF 95 PER CENT OF LABORATORY COMPACTION, (2) OPTIMUM ROLLING TEMPERATURE FOR THE SOLID TIRE ROLLER WAS 180 DEGREES F COMPARED TO 200 DEGREES F FOR THE PNEUMATIC ROLLER, AND (3) PERCENT COMPACTION PRODUCED BY THE SOLID TIRE ROLLER APPEARED SLIGHTLY LESS UNIFORM THAN FOR THE PNEUMATIC ROLLER. THE FOLLOWING RESULTS WERE INDICATED FOR THE WEARING COURSE: (1) THE PERCENT COMPACTION OBTAINED IMMEDIATELY AFTER CONSTRUCTION AT THE OPTIMUM NUMBER OF PASSES WAS APPROXIMATELY 0.9 PER CENT HIGHER ON THE SOLID RUBBER TIRE SECTIONS THAN ON THE PNEUMATIC TIRE SECTIONS, (2) BOTH SOLID AND PNEUMATIC TIRE ROLLERS ACHIEVED THE REQUIRED 95 PER CENT OF LABORATORY COMPACTION, (3) OPTIMUM ROLLING TEMPERATURE WAS 175 DEGREES F FOR THE SOLID TIRE AND 185 DEGREES F FOR THE PNEUMATIC TIRE ROLLERS, AND (4) THE AVERAGE PER CENT INCREASE IN COMPACTION MEASURED SIX MONTHS AFTER CONSTRUCTION WAS 2.2 PER CENT FOR THE PNEUMATIC SECTIONS AND 2.1 PER CENT FOR THE SOLID TIRE SECTIONS. /BPR/
