This report provides descriptions of processes for setting maintenance intervention criteria and allocating budgets. Due to the multi-objective nature of road asset management activities, the decision process including setting maintenance…

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…

This report addresses the issue of calculating ESA-km in the road maintenance funding formula of AusLink This study recommends the use of an average ESA per heavy vehicle class in the funding formula This requires each jurisdiction to prepare from…

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…

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

The state of the art in using GIS to integrate crash data with other information sources, and resources and capabilities available for this purpose in Australia and New Zealand, were established through a literature review and a series of…

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).…
