INFLUENCE OF VISCOSITY OF ASPHALT-CEMENTS ON COMPACTION OF PAVING MIXTURES IN THE FIELD AND DISCUSSION

COMPACTION OF ANY GIVEN DENSE GRADED ASPHALT-CONCRETE PAVING MIXTURE BY ROLLING DURING CONSTRUCTION IS INFLUENCED BY THE VISCOSITY TEMPERATURE CHARACTERISTICS OF THE ASPHALT- CEMENT, THE TEMPERATURE OF THE MIX DURING COMPACTION, THE GRADUAL INCREASE OF STABILITY AND DENSITY OF THE MIX AS ROLLING PROCEEDS, THE RATE OF COOLING OF THE MIX BEHIND THE SPREADER, TYPE OF ROLLING EQUIPMENT, AND THE USE OF LOW RATHER THAN HIGH VISCOSITY ASPHALT-CEMENTS. THE INFLUENCE OF THE VISCOSITY OF THE ASPHALT-CEMENT ON COLD WEATHER PAVEMENT CONSTRUCTION, AND ON THE RATE AT WHICH A FINISHED ASPHALT PAVEMENT IS DENSIFIED BY TRAFFIC IS REVIEWED. OF CURRENT COMPACTION EQUIPMENT, IT IS INDICATED THAT PNEUMATIC-TIRE ROLLERS EQUIPPED FOR RAPID ADJUSTMENT OF TIRE INFLATION PRESSURES OVER THE RANGE OF FROM ABOUT 25 TO 150 PSI OR MORE, APPEAR MOST LIKELY TO BE CAPABLE OF ACHIEVING 100 PERCENT OF LABORATORY-COMPACTED DENSITY BY ROLLING DURING CONSTRUCTION.
