A STUDY FOR IMPROVING THE DURABILITY OF PLANT-MIX ASPHALT SURFACES IN SOUTH CAROLINA
The primary objectives of this research are to determine practical measures for improving the service life of asphalt surfaces. To this end, more than 50 sites of existing highway pavements and 36 experimental pavement sections along various highways in South Carolina were investigated. While at the present (1978), the time is insufficient for reaching definite conclusions regarding the effect of selected variables on pavement durability, preliminary analyses of available data and recommendations for research impletation are made. The findings and recommendations are related to the compaction of the surface course on roads of different traffic catagories, the reliability of nuclear gauges for determining the density of surface courses, the change in laboratory compactive effort for the preparation of test specimens to simulate pavement density, the modification of the air voids requirement for the design of a particular type of surface course mixture, and the comparison of two commonly used methods for determining the theoretical maximum density of bituminous mixtures. /FHWA/
