PROPERTIES AND APPLICATION OF ARM-R-DRAIN POROUS ASPHALT MIXES
On account of the improved safety which it offers the road user and the reduction in noise pollution resulting from its use, porous asphalt may be considered as one of the more important recent developments in asphalt paving technology. However, on account of its open structure, porous asphalt needs to be designed to resist the effects of environmental forces, such as moisture, ultra-violet radiation and temperature, of which all may affect the durability of the binder and consequently that of the asphalt mix. Arm-R-Shield, being a bituminous binder to which recycled rubber crumbs and aromatic oils are added in order to enhance durability and the rheological properties of the binder system, enables porous asphalt mixes to be designed with greater void contents and improved durability. In this paper, the development of Arm-R-Drain, its properties and implementation are discussed. (A) For the covering abstract of the conference see IRRD 873950.
