Rubberised binders

Polymer modified binders (PMBs) are widely used in Australia. Currently the most common types of PMB are scrap rubber bitumen blends and proprietary materials based on the synthetic polymers EVA and SBS. However, with the widespread acceptance of PMBs, new types of polymer are being developed for roadmaking use. The practitioner needs guidance on when PMBs are the appropriate treatment for a problem, on which PMBs are the ones to use, and on how to specify the material so he can be sure of getting what he wants. To address this need, ARRB organised a National Workshop on Polymer Modified Binders which was attended by representatives from manufacturers, applicators, users and ARRB. At the Workshop it was decided that there was insufficient information on the performance and properties of PMBs for specifications to be written but it was recommended that work start immediately on obtaining the information. As a result, a joint ARRB/Austroads project was established. Two Working Parties have recently started work in the areas of (i) Field Performance and Applications and (ii) Development of Specifications. They are charged with producing guide-lines for the use of PMBs and draft specifications. A Workshop will be organised when these tasks are complete to acquaint with the findings (A).
