This document provides a guide to the selection of modified binders including multigrade bitumens for different treatments and service conditions, and to assist in the use and interpretation of the Austroads Specification Framework for Polymer…
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 investigates the origins of the current Unconfined Compressive Strength (UCS) criteria that differentiates modified granular materials from bound materials. Based on the review, a number of changes to the UCS design criteria are…
The report reviews current Australian and selected international structural design methods for pavements on lime-stabilised subgrade layers. Research to investigate in-service strength and modulus of lime-stabilised materials is also summarised. The…
To assess permanent deformation of granular materials repeated triaxial tests are currently used. A previous research project highlighted interest in using a wheel-tracking test to obtain a better agreement with field performance.
A new wheel-tracker…
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…
To assess permanent deformation of granular materials, repeated triaxial tests are currently used in Australia. A previous research project highlighted interest in using a wheel-tracking test to obtain a better agreement with field performance. A…
This report presents the summary of project activities conducted during the 2011/12 season, including a summary of the LTPP/LTPPM pavement condition survey results, a brief summary of the development of probabilistic road deterioration (RD) models…
