This Pavement Work Tips provides guidance on estimating the amount of time available to achieve effective compaction under various conditions.

This Pavement Work Tip discusses some of the factors that affect riding quality, and how to ensure a smooth riding asphalt pavement.

This Pavement Work Tip outlines the influence of temperature and binder viscosity on handling properties of asphalt using different binders.

The current practice of balancing traffic density or distributing traffic evenly in a road network is essentially subjective and is achieved manually through expert opinions. This report summarises these expert opinions and investigates whether…

A major study was undertaken to determine relationships between binder rheological properties and the rut resistance of asphalt mixes, as indicated by the laboratory wheel tracking test. Twelve binders, including three bitumens, a Multigrade binder…

The use of warm mix asphalt (WMA) appears to be increasing throughout the developed world in place of conventional hot mix asphalt (HMA). Acceptance depends upon confirmation of the environmental benefits and that on-road performance is at least…

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…

The report describes the work undertaken in the first year of a two-year project to assist implementation of a new Australian asphalt mix design procedure. The main tasks undertaken were (i) preparation of an update for the Australian Provisional…

This framework for specifying asphalt has been prepared by Austroads and the Australian Asphalt Pavement Association, with input from the New Zealand Pavement and Bitumen Contractors Association (BCA) to promote national uniformity and good practice…

This report describes a benchmarking study of road asset management decision processes. The study was conducted in 1999, and involved 12 road agencies in 5 nations, with 8 in Australia, and 1 in each of France, New Zealand, Switzerland and the…
