|Dear <<First Name>>,
Welcome to the 7th edition new AustStab newsletter, renamed eStab.
In November 2012 AustStab were:
Advised by RMS (NSW) that several road maintenance specifications were updated and will be available for download from 1 December on the RMS website;
Continued the review of the Streetworks Code of Practice in Victoria;
Prepared to deliver the Townsville Insitu Stabilisation Training course in conjunction with CPEE on 27 - 28 November 2012 (Registrations closing soon - for more information click here);
Responded to a query about stabilisation (Click here for our FAQ section) ;
Uploaded the sprayed seal technote, discussed at the AustStab conference, to the bitumen working group folder in the members only Intranet section of the website; and
Continued to work on the association pillars of education, research, promotion and setting standards.
Training developments continue in Queensland
In November I continued working with TMR Queensland to identify a series of core competencies in stabilisation. These competencies would be transferrable across all states when completed.
AustStab are continuing to deliver the highly successful Insitu Stabilisation course in association with CPEE. The training course is currently under review and comments and additional feedback would be welcomed.
AustStab will continue to actively campaign to have this course recognized as a minimum requirement for all staff, including operators and supervisors completing stabilisation and pavement recycling operations.
To email me with feedback on the course please click here.

Spreading of Powder Binders
Powder binders are applied using one of two techniques:
Using a load calibrated mechanised spreader from a rear or centrally located drop chute; or
Spreading the binder from a reclaimer with an integrated hopper where the binder is carried in the reclaimer and spread ahead of the mixing chamber.
While it is common to specify binder content as a percentage of the compacted dry mass or pavement, construction adopts a calculated spread rate in terms of kg/m2. Two methods of verifying the binder application rate for mechanical spreaders are:
More information on spreading of powder binders is available in Section 12.2.3 of the AustStab Pavement Recycling and Stabilisation Guide. It can be ordered by clicking here.
Use of trays or mats which are weighed; and
Use of measurements from on-board load cells on the spreader.
Minutes to all meetings held at the 2012 Conference are now available for review and action in the Intranet section of the AustStab website.
