Abstract

The increase in global temperature especially in tropics with devastating consequence on the performance of bitumen in pavements, high cost of fuel and other environmental factors makes it imperative to deviate from the conventional hot mix asphalt (HMA) to a more environmentally friendly method of producing asphalt mixtures. The mixing of asphalt binder with an additive to lower the mixing and compaction temperature, with better resistance to rutting damage, less fuel consumption and relatively low emissions as compared to conventional way of mixing asphalt could, be achieved with the warm mix asphalt (WMA) the technology. This study investigated the characteristics of bitumen 60/70 and 80/100 penetration grade modified with a commercial additive sasobit wax, a long chain aliphatic hydrocarbon (LCAH). In this study the fundamental rheological and mechanical tests were conducted, which include penetration test, softening point, viscosity test, the rolling thin film oven test (RTFOT), and pressure age vessel (PAV). The trend is with an increase in additive the binder viscosity decreases at high temperature as it stiffens and becomes hard at low temperature, thereby increasing the softening point and reducing the penetration of the binder. © 2010 Faculty of Construction and Land Use, The Hong Kong Polytechnic University.
