The work documented in this report demonstrates the use of existing Austroads deterministic road deterioration (RD) models in a probabilistic approach to estimate the possible predictions for the dependent variables of these models. This approach…
This report details of the performance of polymer modified binder (PMB) trial sites in South Australia and New South Wales after 12 months service life. It includes related information such as the seal designs, binder testing in the laboratory, site…
This report presents the results of a literature review and laboratory study which was conducted as part of the development of a new-long term ageing (durability) test for bituminous binders used in sprayed seals in Australia.
The literature review…
This report provides a brief state-of-the-art review of current traffic speed deflectometer (TSD) practice based on information gained from attending the deflection at road traffic speed workshop held in the UK in June 2012.
The current state of…
Bitumen, an important component used in road construction in Australia and New Zealand, is manufactured from a finite, non-renewable crude oil resource. A number of commercially available alternative binders and bitumen extended binders have been…
This report describes the planning and construction of Australian field trials which will measure of the relative performance of polymer modified binders (PMBs) used in strain alleviating membranes in sprayed bituminous sealing. Issues addressed in…
This document is an update of the design procedure for double/double sprayed seal surfacing. The information supersedes that in Update of the Austroads Sprayed Seal Design Method(Austroads 2006), and replaces Sections 6, 7 and 8 in that document.

This report provides a worked example for developing skid resistance investigatory level guidelines.
The worked example is sourced from Main Roads Western Australia (MRWA) and relates to texture measurement as a surrogate for skid resistance. A…
