Specification framework for polymer modified binders and multigrade bitumens

This Specification Framework for Polymer Modified Binders (PMBs) and Multigrade Bitumens has been produced by an Austroads Project Group. The specification is based on a set of test procedures that have been in use throughout Australia for several years. The intention of the specification is to achieve performance in the field for both sprayed seal surfacing and asphalt pavement applications. Specification limits are currently framed around the results of nationally coordinated field trials and laboratory studies, supplemented by Austroads Member Authority experience gained over the last few years.
