Laboratory Performance Evaluation on Polymer Modified Porous Asphalt Concrete
This paper presents the details of the laboratory performance evaluation of the three types of polymer modified binders and their respective porous asphalt concrete. The same gradation was applied to all the mixtures and the base bitumen was Shell 60/70. The binder test results indicate that the SBR and SBS modified binders have the smaller temperature susceptibility and exhibit better performance in resisting ageing, rutting, and fatigue than the conventional penetration 60/70 binder. When evaluated in a series of laboratory tests designed to assess the fundamental mechanical properties and durability performance of porous asphalt concrete, the results show that the SBS modified porous asphalt concrete exhibit the most overall satisfactory performance with respect to stiffness, dynamic creep deformation, rutting, and moisture resistance damage among the three types of porous asphalt concretes studied. Based on the lab results and the cost-effectiveness analysis, the SBS modified porous asphalt concrete is recommended as the most favorable material to be used as a friction course in Hong Kong.
