This report describes inspections conducted on double/double primerseals constructed in Victoria.

It is not typical practice to use two-layer primerseals, or polymer modification in primerseals, and methods to do so are not described by Austroads…

This report details the findings from visual inspections conducted on two Austroads sprayed seal field trials: a non-modified binders trial near Gisborne,

A mobile pavement surface wear rig has been constructed, which aims to gain an improved understanding of the failure mechanisms that are particular to the pavement surfacing layer – as distinct from the structural layers – that may be caused by…

This report provides asset managers with practical guidance in the development and delivery of effective resealing programs. It builds on accumulated experience of previous studies and a review of sprayed seal performance throughout Australasia.

This report documents the surface life prediction models that have evolved from the long term sampling of the bitumen in sprayed seals and thin asphalt surfaces. The estimation of surface life is predicated on the basis of the mechanism of bitumen…

To assist member authorities in the management of road assets to provide better safety outcomes, this research program has been developed to assess the safety implications of road deterioration, the safety benefits of asset restoration, and the…

All road and traffic authorities need to direct their funding wisely to road safety treatments that ensure the most cost-effective returns in crash and injury reductions. In order to do this, accurate information is required on the expected benefits…

Improved RD models for sealed granular and asphalt pavements are needed. Pavement performance history data from state road authorities and New Zealand (SRAs) were used for calibrating RD models. The calibration and refinement of RD models is…

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).…
