There is a need to improve the Austroads procedures for mix design and structural design of foamed bitumen stabilised materials. This progress report summarises the mix design test methods drafted to date and those planned for 2015–16 within the…

The current version of the Austroads sprayed seal design method was published in 2006 and has been in use for the last nine years. During recent times, a number of sprayed sealing practitioners have indicated that the basic voids factor for single/…

The report covers a variety of topics related to improving the design procedures for asphalt pavements in Australia. Literature reviews of perpetual pavement design concepts and the relationship between flexural and compressive modulus were…

The current Austroads approach to assess the relative damaging effects of different axle groups on road pavements is by comparison of the peak static pavement deflection response under the axle groups. The assumption that deflection is the most…

Traffic loadings on Australia’s extensive sprayed seal network have increased, particularly with freight efficiency resulting in longer and heavier loads being transported by prime movers.

This report details the development of a model to describe…

This report presents the findings from the second year of a three-year Austroads study which aims to maximise the re-use of reclaimed asphalt pavement (RAP) in new asphalt mixes.

A survey was conducted in Australia to identify the important issues…

This Pavement Work Tip provides a guide to calculate the volume of liquid bituminous binders relative to a standard temperature of 15°C.

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…

The Austroads Guide to the Selection and Design of Asphalt Mixes does not address the design of mixes containing Recycled Asphalt Pavement (RAP). The report contains the additions and amendments which should be made to the next revision of the Guide…

A new, performance related asphalt mix design procedure was developed to address increased traffic stressing of pavements and to evaluate new mix types and new binder formulations. A series of Workshops was held in the capital cities of Australia…
