dc.descriptionAbstract: Gyratory shear tests and repeated load triaxial compression tests were conducted on five different base courses furnished by the New Jersey Department of Transportation (NJDOT). Two of the materials, one stabilized with asphalt and the other unstabilized, were open-graded aggregate bases designed to provide a high degree of porosity. The other three materials were conventional bases currently being used by the NJDOT. The conventional bases were a high-quality, asphalt-stabilized base material, a crushed rock, and a pit-run gravel. The laboratory tests indicated that for dynamic loads, such as would be the case for high-speed highway traffic, the open-graded bases would perform better than or as well as the nonstabilized conventional bases but not as well as the high-quality stabilized base. For static loading, the nonstabilized bases were superior to the asphalt-stabilized bases. The minimum coverage requirement for the open-graded bases is estimated to be approximately 6 in. The data provided by gyratory testing proved to be useful in evaluating the base materials, and the recommendation is made to continue development of gyratory testing for evaluation of pavement materials.-
