PERMANENT DEFORMATION EVALUATION OF MODIFIED WASTE PLASTICBITUMEN IN ASPHALT CONCRETE USING FUNDAMENTAL AND SIMULATIVE METHODS
The paper discussed the fundamental and simulative method in assessing permanent deformation of modified waste plasticbitumen in asphalt concrete. Waste plastic (HDPE) obtained from milk bottle plastic was used to modify 60/70 penetration grade bitumen and Its effect on basic bitumen properties was tested over a range of test temperatures. The Marshall stability tests were carried out to determine the optimum bitumen content and optimum waste plastic content of asphalt concrete. The optimum waste plastic content in binder was found to be 1.5% by weight of binder. The permanent deformation evaluation of asphalt concrete with and without waste HDPE was evaluated in laboratory using fundamental method (Repeated Load Axial Test) and simulative method (Wheel Tracking Test) at a range of test temperatures. The analysis data indicated that both tests fundamental and simulative test had significant correlation with each other. Both test results was consistent that the performance of asphalt concrete prepared using waste plastic were more resistance on permanent deformation over a range temperature
