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…

This project has developed guidance on how signal management and operation should be undertaken to realise the intent of network operation planning and achieve the desired performance outcomes for road users.

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/…

This report provides a generic framework for private investment in public road infrastructure.

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…

This report reviews current practices and research evidence on the co-location of three types of signs: direction signs (DS), variable message signs (VMS) and variable speed limits/lane control signs (VSL/LCS). An advanced driving simulator study…

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 report documents research to determine if the size of electronic regulatory speed signs (ERSS), such as variable speed limit signs, could be reduced without adversely impacting efficiency of driving or safety.
