Some recent problems with polymer modified binder (PMB) seals have been attributed to lack of initial adhesion of the binder to the sealing aggregate. This suggests that higher levels of cutter than those given in an Austroads Guide may be necessary.…

This Pavement Work Tip provides a handy reference to the recommended practice for cutting sprayed sealing binders.

This Pavement Work Tip provides a guide to selection and use of either prime and seal, or primerseals, as initial treatments for granular pavements.

This Pavement Work Tip is a practical guide for restoring texture to bleeding or flushed surfaces by applying additional aggregate with the assistance of chemical solvents.

This report documents the surface life prediction models that have evolved from the long term sampling of the bitumen in sprayed seals and thin asphalt surfaces. The estimation of surface life is predicated on the basis of the mechanism of bitumen…

A road trial was established at Gisborne on the Calder Highway. The aim of the trial was to review the performance of sprayed seals constructed from a number of binder types. Class 170 is typically used in Victoria for sprayed seals and a section…

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…
