This report is an update of earlier Austroads sprayed seal design procedures based on the philosophy of filling voids in the aggregate matrix with binder to a depth of about one half to two thirds the height of the aggregate when laying on its least…

Austroads has produced a series of test methods developed from various technical projects, principally in the bituminous materials area (asphalt, binders, slurry and sprayed seals). The Austroads system of managing the test methods has enabled…

This test method sets out the procedure for determining the amount of binder drain-off likely to occur in an asphalt mix during storage and transport. The method may be used to determine the amount of binder drain-off at the maximum mixing…

This method describes the procedure for the recovery of sprayed seal samples from the pavement without disturbing the sealing aggregate orientation. The method stipulates how the void content of the sample is determined.

This test method sets out the procedure for assessing the degree of absorption of a primer or primerbinder by a given road gravel in bituminous surfacing work.

An Austroads national workshop on sprayed sealing was held to assist development of a research program and identify challenges to the future use of seals. Delegates identified key issues under the themes of: safety and traffic management

This test method details the requirements for determining the flexural stiffness, phase angle, dissipated energy per cycle, cycles to failure and cumulative dissipated energy at failure of asphalt subjected to repeated flexure by cyclical four-point…

An existing model predicted binder life by combining a binder hardening (increase in viscosity) model and a distress viscosity model. Inputs for the two models were site temperature parameters, binder durability (resistance to hardening) and seal…

An existing model predicted maximum seal life by combining a binder hardening (increase in viscosity) model and a distress viscosity model. Inputs for the two models were site temperature parameters and binder durability (resistance to hardening).…
