Guide to Pavement Technology Part 2: Pavement Structural Design provides advice for the structural design of sealed road pavements. The advice has been generally developed from the approaches followed by the Austroads member agencies. However, as it encompasses the wide range of materials and conditions found in Australia and New Zealand, some parts are broadly based.

This Part covers the assessment of input parameters needed for design, design methods for flexible and rigid pavements and gives guidance on the economic comparisons of alternative pavement designs.


In association with the revised 2017 edition of the Austroads Guide to Pavement Technology Part 2, pavement design software incorporating a finite element method based pavement response to load model has been developed.

This web-based software tool, AustPADS, is currently being finalised and it is expected to be made available early in 2018 for use by member road agencies and industry organisations working with road agencies.

A user name and password is required to access the software. Advice on establishing access to the AustPADS software tool will be provided when the software is available.

A 12 month member agency focussed trial of the AustPADS software has been agreed by the Austroads Pavements Task Force to commence in early 2018.

The primary target users for AustPADS are Austroads member road agencies in Australia and New Zealand and industry organisations working with member road agencies. During the trial period, access credentials will be prioritised for this target user group. Access may not be granted to other potential users until a later date.
