Australian Standards Under Review

A review of AS1289 6.1.1 CBR is under review. Howard Jeffery-Wright, Downer Infrastructure, is attending the review committee on behalf of AustStab.

Howard advised that the this document will shortly be available for public comment. Important changes to curing and preparation of specimens along with equipment checks will be incorporated in the review. Members should familiarise themselves with the changes, and comment on the changes if necessary.

If you require additional information on this review process, or would like to participate in review of Australian Standards on behalf of AustStab, please contact Leah for more information at leah.fisher@auststab.com.au.

ARRB Unsealed Roads Symposium

In October 2013 ARRB hosted the Unsealed Roads Symposium, and AustStab was represented at this event.


Copies of the presentations made at the Symposium are now available on the ARRB website are available by clicking here.

Laboratory Testing CBR

One of the most common empirical tests used to characterise the strength of the subgrade and pavement materials is CBR. It is both an indirect indicator of shear strength and, to a lesser extent, the bearing strength.

The CBR has become the universal soil test that is used to characterise subgrade materials on which pavement thickness design charts are based. It is also used to characterise the pavement subbase materials with CBR values generally less than 100%. This test is not considered sufficiently reliable to characterise pavement base materials with CBR values exceeding 100%.

AustStab Conference 2014 - Save the Dates

AustStab will host the 19th Annual AGM and 3rd Annual Awards dinner on 11 - 13 August 2014 in the Hunter Valley.

Following the successful conference on the Gold Coast in 2013, members requested that we include presentation of papers providing information on the latest technology and research as well as more detailed presentations regarding the Award nominations for the year.

Proposals for papers to be presented are now being accepted for the conference. Guidelines for the presentations are available from Leah Fisher. All presentations will be subject to the approval of the Council.
