The current version of the Austroads sprayed seal design method was published in 2006 and has been in use for the last nine years. During recent times, a number of sprayed sealing practitioners have indicated that the basic voids factor for single/…

Traffic loadings on Australia’s extensive sprayed seal network have increased, particularly with freight efficiency resulting in longer and heavier loads being transported by prime movers.

This report details the development of a model to describe…

This Pavement Work Tip provides a guide to the use of priming and primersealing as initial treatments on stabilised pavements.

This Pavement Work Tip is a practical guide to sprayed sealing in areas where a pavement may be affected by drought or salt content in its construction.

This report presents an extensive literature review of pavement surface texture measurement methods with a specific interest in how they affect operator safety and delays to traffic. The literature review shows that there are a number of methods in…

In 1993, Austroads performed an extensive trial of foamed bitumen sprayed sealing in Australia, as a part of environmental and energy effective sealing technology development program. The trials were conducted in various states and reported to be…

A review of bleeding or flushed seals was undertaken to determine what physical changes had taken place within the seal that had resulted in the binder lying at or close to the surface. The evaluation process used a visual appraisal and a digital…

Improved RD models for sealed granular and asphalt pavements are needed. Pavement performance history data from state road authorities and New Zealand (SRAs) were used for calibrating RD models. The calibration and refinement of RD models is…
