This test method sets out the procedures for the measurement of the stress ratio of binder samples under specific conditions using the dynamic shear rheometer (DSR). A major failure mode of sprayed seals and asphalt pavements is fatigue cracking of…

This report considers the use of marginal and non-standard materials in road construction and maintenance. It concludes that considerable evidence exists, both nationally and internationally, that supports the wider use of marginal and non-standard…

This test method sets out the procedures for the ageing treatment of bitumen samples under specific conditions using the Pressure Ageing Vessel (PAV), and also the determination of the complex viscosity of treated samples under specific conditions…

This test method sets out the procedures for the determination of the force ratio and toughness of bitumen and PMBs under specific conditions of deformation using the ARRB extensiometer.

This test method provides a guideline for the design of a blend of RAP binder, virgin binder, and/or rejuvenating agent to a target viscosity.

A new rut resistance approach based on the wheel-tracking test for unbound granular materials has been developed. The objective of the Austroads project TT1819 is to validate the wheel-tracker laboratory approach against large-scale Accelerated…

This test method sets out the procedures for the determination of consistency, consistency 6%, stiffness and elastic recovery of polymer modified binders (ARRB elastometer), under specific conditions of deformation, using the elastometer developed…

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…

Recognising the importance to pavement designers, asset managers and policy makers of an improved understanding of the relationship between different multiple axle group loads (single, tandem, triaxles, etc.) and road pavement performance, Austroads…

This method describes a procedure for determining the particle size, shape and contaminants of crumb rubber.
