Abstract:

The objective of this study was to develop procedures for making and testing specimens made with asphalt-rubber and aggregates. The investigation was aimed at finding a method or methods for (a) mixing the high-viscosity asphalt-rubber with aggregates, (b) forming test specimens made with this resilient material, and (c) testing the compacted specimens for characterization by using some common procedures. The above factors are discussed along with results obtained for Hveem stability, cohesiometer value, axial tension, double-punch tension and dynamic modulus of elasticity, and resistance to debonding under a dynamic repeated pore-water pressure exposure. In general, it was found that good aggregate coating can be obtained with a common laboratory mixer at the usual mixing temperatures, that California-tamping-foot compaction was not possible and that vibratory compaction yielded higher densities than static compaction, that compacted specimens required a storage period of three days in the mold at room temperature, that testing for strength had to be performed at room temperature, that testing for strength had to be performed at room temperature or lower, and that expected low strength and durability are attributed to high air-void content.
