Abstract

The resilient behavior of asphalt stabilized soil under repeated loading in terms of the change in the potential of deformation and shear failure was investigated in this work. Asphalt stabilized soil specimens of 100mm diameter and 70mm height and 152mm diameter with 127mm height have been prepared in the laboratory and compacted to a target density at optimum asphalt requirement and at 0.5% of asphalt above and below the optimum. Specimens were tested for deformation and resilient modulus under repeated shear stress. The deformation of the specimens has been captured along the load repetition process with the aid of linear variable differential transformer (LVDT) under controlled stress and environmental conditions in the pneumatic repeated load system (PRLS) until failure. For large size specimens tested under single punch shear stress, the resilient deformation decreases by (70, 51, and 47) % as compared with pure soil at fluid content equals to (15.5, 16, and 16.5) % respectively after 1200 load repetitions. For small size specimens tested under double punching shear test after thirty and eight days curing, the resilient modulus increased by (442, 362, and 216) % for fluid content equals to (15.5, 16, and 16.5) % respectively after load repetitions equal to 1200. Data of the two testing techniques regarding resilient deformation rate under single and double punching shear stress was analyzed and compared. It was concluded that eight days curing and double punch shear testing are reported as the optimum time and test technique for enhancing proper resilient modulus. Asphalt stabilization exhibit positive impact on resilient modulus, it increases Mr by a range of (600, 700, and 100) % for double punch at 30 and 8 days curing and single punch at 8 days curing after the addition of cutback asphalt as compared with natural soil.
