Guidelines and Specification for Microsurfacing provides guidelines for the use of microsurfacing treatments in Australia. Microsurfacing is presently the only type of bituminous slurry surfacing applied in Australia. The document was produced by…

This report provides a broad indication of the methodology, project components, expertise available and indicative costs required to produce a robust national willingness to pay (WTP) estimate of the social cost of Australian road crashes.

This report introduces key methodologies and the associated challenges with regards to defining and measuring travel time reliability, in particular, for improving the valuation of travel time in project appraisal by Australian jurisdictions.

Austroads updates of unit values and cost estimation algorithms used as inputs for urban and non-urban road investment evaluation models have become the industry standard in Australia. Updates provide a comprehensive and detailed coverage in both…

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).…

The report summarises the activity in the Austroads sprayed seal design project for 2003/2004. Austroads member authorities were surveyed to determine if there were further issues with sprayed seal design that needed resolution. Recommendations for…

In response to a concern that road evaluation models utilised by Australian road authorities were yielding inconsistent and inaccurate estimates of road user benefits, Austroads surveyed and assessed evaluation models currently in use. Information…
