In this edition of the eStab newsletter  we review what's been happening at AustStab / give you some details of the Calder Freeway trial and provide some insight into cementitious stabilisation. We hope that you find it informative, and pass it around to your colleagues.

Dear <<First Name>>,

Welcome to the 11th edition AustStab newsletter - eStab.

In March 2013  at AustStab:
  • Completed the foamed bitumen trial site on the Calder Highway in Victoria (See below for more information);
  • We completed the review on the AustStab Construction Tip - Profilers versus Stabilisers. ;
  • We hosted the Victorian Civil Contractors Alliance quarterly meeting;
  • We revised the AGM dates in Queensland to 12 - 14 August 2013 and confirmed the location ;
  • We mourned the loss of Geoff Shadforth of AusRoads;
  • We published the forward Council meetings for 2013 on the calendar; and
  • Continued to work on the association pillars of education, research, promotion and setting standards.

Assist and coordinate research

This month AustStab members combined their skills to construct a section of foamed bitumen pavement for field performance monitoring on the Calder Freeway as part of the Austroads Project TT1825 Mix design and field evaluation of foamed bitumen stabilised pavements. Funding for the three year project was allocated in 2012. The project outcomes will be reported to the Pavement Structures Group for Austroads in due course. More information is available from David Hazell.

We thank our members for their generous donations for the project. Donations for the project were made by Downer, Shell, Sibelco, SPA, Stabil-lime Group and VicRoads.

Cementitious Stabilisation

Cementitious stabilisation uses cement or blended products that contain some or one of the following supplementary materials, lime, flyash or slag. These supplementary additives reduce shrinkage and develop strength more gradually with a resultant reduction in cracking.

The cementitious material reacts with the water in the soil to form a cementitious material. The resultant pavement is defined as modified or lightly or heavily bound dependent in the strength of the material which is dependent on the proportion of cement added.

Cementitious stabilisation can be used in subgrades, subbases or bases.

For more information on cementitous stabilisation click here or look in Section 7 of the Guide.
