This report details the experimental program, analysis and findings of the assessment of the impacts of axle mass increases on road deterioration for sprayed seal surfaced unbound granular pavements. Load-damage exponents ranged between two and four…

This document describes the results of field trials held in Christchurch, New Zealand in May 2005. The objective of the trials was to gain further understanding of the complex relationship between the various test devices currently utilised to…

This report is an update of earlier Austroads sprayed seal design procedures based on the philosophy of filling voids in the aggregate matrix with binder to a depth of about one half to two thirds the height of the aggregate when laying on its least…

This report gives information on the development of a procedure to fractionate bitumen using an Iatroscan liquid chromatography system, and also presents test results on a range of Australian bitumens. An introduction discusses the topic of bitumen…

Selection of maintenance techniques is always a balance between the administering authority costs and social and environmental costs and outcomes. This project provides practical information and a methodology (including a worked example) for…

This Supplement is intended to assist those required to plan and design new pavements for lightly trafficked situations. It caters for design traffic up to 105 ESA for flexible pavements and 106 Heavy Vehicle Axle Groups for rigid pavements. It is a…

This Specification Framework for Polymer Modified Binders (PMBs) and Multigrade Bitumens has been produced by an Austroads Project Group. The specification is based on a set of test procedures that have been in use throughout Australia for several…

A general literature survey and a user survey was conducted to obtain information on existing data aggregation methods and their status in Australia and New Zealand. The responses to the survey indicated that all agencies use or are close to…

An existing model predicted binder life by combining a binder hardening (increase in viscosity) model and a distress viscosity model. Inputs for the two models were site temperature parameters, binder durability (resistance to hardening) and seal…

An existing model predicted maximum seal life by combining a binder hardening (increase in viscosity) model and a distress viscosity model. Inputs for the two models were site temperature parameters and binder durability (resistance to hardening).…
