AustStab puts the spotlight on standards for new products

AustStab is often contacted by chemical product distributors  who have a new product which they maintain is suitable for use as a binder in road stabilisation. The problem is that too often there is no supportive evidence of the product's properties, its effect on different soil types and the design procedure.

AustStab, in conjunction with many road authorities, is offering a service to the chemical product distributors. The service is to advise them of the State Road Authority’s requirements so that the new product can be assessed. This would normally require a suite of tests to be carried out by a NATA registered laboratory to prove the products claims. The assessment by a pavement engineer might also be required to ascertain a suitable design procedure. Each road authority could then make an informed decision on whether they wished to take the product approval further using field trials.

More Information

The contractor is coming .. What should I check before he comes?

AustStab recommends that the supervisor and engineers should complete the following checks ...

1. AustStab/ARRB certification;
2. A complete understanding of the pavement materials;
3. Services location information;
4. An up-to-date weather forecast.

Construction tips for many aspects of stabilisation are available on the association website.

It is important to remember that adverse weather conditions may be detrimental for road stabilisation. The progress and quality are impaired if undertaken during heavy rain. If mixing or compacting after heavy rain fall, the moisture content of the materials may increase beyond an acceptable limit and under such circumstances consideration should be given to aerating in order to reduce the moisture content and aid in achieving compaction.

More information about construction issues are available in section 12 of the Pavement Recycling and Stabilisation Guide. (Click to follow link)


Correction: Last month we incorrectly named our valued member Andrew Walters Construction. This should have read Andrew Walter Constructions.

Please accept our apology for this error Andrew.
All of the links and other details in the article were correct.

We will shortly be submitting an article for the Australia Main Roads Construction News on behalf of AustStab. Members are encouraged to advertise during the AusStab stablisation edition. For more information click here.

Until next month remember the best quarry is the one we drive over everyday - so why not recycle it?
