News from the Centre of Stabilisation expertise in Australia

A monthly newsletter informing you of initiatives and happenings in the stabilisation industry in Australia

Dear <<First Name>>

In March 2015, AustStab:

  • Completed the construction of the foamed bitumen trials in Victoria with Austroads
  • Hosted the Queensland Working Group Meeting
  • Completed re-accreditation audits in Queensland
  • Welcomed our 1000th delegate to the CPEE Insitu Stabilisation Training Course
  • We continued to deliver on the pillars of the association.
Some upcoming events:
  • 13 April 2015 - Western Australian Working Group Meeting
  • 15-16 April 2015 - Darwin AustStab CPEE Training Course
  • 20-21 May 2015 - Horsham AustStab CPEE Training Course
The cyclone season is due to end in April in the North of Australia. There have been a number of late season events this year. I am still seeking information about successes, and possibly any failures, that have occurred in the most recent events. Preliminary feedback from Queensland was that the NDRRA funded roads were performing well.

In preparing for the onset of autumn in the Southern states, with periods of Autumn rains likely, it is a timely opportunity to remind people of the benefits of lime stabilised subgrades. Historically lime subgrades provided all weather access to construction sites. Lime stabilised subgrades with quick lime are also often used to dry sites out quickly, and if the lime demands tests are met can produce a permanent reaction with flow on benefits to the projects.

Ballan Austroads Foamed Bitumen Trial Site


Ballan - Daylesford Road, outside Melbourne

This is the foamed bitumen trial site is located on the Western Highway, west of the Ballan-Daylesford Road (about 78 km from Melbourne). The Western Highway is a heavily trafficked national highway linking Melbourne and Adelaide.

The site has two foamed bitumen designs applied to the site. It will be monitored for a period of approximately 3 years. The pavement will allow Austroads
to evaluate the in service performance of an under-designed pavement compared to the Austroads predictions (designed to fatigue within 3 years).

1000th Delegate attends AustStab CPEE Insitu Stabilisation Training Course
Always happy to celebrate momentous occasions, Greg White (AustStab) and Bob Andrews (CPEE) were on hand to congratulate Ray Hussey from Conargo Shire Council, Deniliquin at the Wagga Wagga course in March 2015.

AustStab and CPEE have delivered training on insitu stabilisation in the current face-to-face format for nearly 5 years, throughout Australia. Bob and Greg clearly have a strong professional report built over that time and this is enjoyed by the delegates of each course. Their format and delivery style remains engaging and most importantly informative, presenting the very latest information on materials, design methodologies and construction practice. They have been well supported by industry, with Scott Young (formerly Downer), Daniel Orriss and Andrew Middleton (Stabilised Pavement of Australia), Leah Fisher (AustStab), Heath Curnow (Stabilime) and many other presenting sections of the course.
