Moisture damage in asphalt (also known as stripping) can significantly reduce the durability and strength of asphalt pavements, often resulting in expensive repairs. Hydrated lime is widely used in Australia to reduce the moisture susceptibility of…

Austroads has completed a project to replace the obsolete gyratory compactors used in design and quality control testing of asphalt mixes and update its Guide to Pavement Technology Part 4B: Asphalt. Austroads asphalt mix design procedure currently…

This report details the testing of 21 Austroads jurisdictions mixes and one airport mix to develop a relationship between the Austroads Gyropac Gyratory compactor, which is now redundant, and the Servopac (setup to AS/NZS) and Superpave Gyratory…

Hydrated lime is widely used in Australia to reduce the moisture susceptibility of asphalt mixes in service. However, the local asphalt industry is concerned about the sustainability of the continued use of hydrated lime in asphalt. This report…

This Pavement Work Tip provides information on the essential elements of the calibration process for bitumen sprayers.

This Pavement Work Tip details the general principles affecting aggregate size selection and provides recommended aggregate sizes for a range of sealing treatments.

This Pavement Work Tip outlines the procedure to allow for surface texture variations by pre-spraying of additional binder.

This Pavement Work Tip provides instructions on how to minimise sprayed sealing handwork and gives some suggestions for maximising the use of a sprayer when sealing tapers and roundabouts.

This Pavement Work Tip describes the requirements for the selection of an appropriate design aggregate spread rate and the calibration of aggregate spreading equipment for uniformity and consistency of output.

This Pavement Work Tip refers to minimising the risk of bleeding when carrying out sprayed sealing work during extreme hot weather events, especially when subject to slow moving or stationary heavy traffic, or unusually heavy loads.
