Proposed Methodology for Upgrading Bridge Barriers
The AS 5100 Standard provides requirements for multiple-performance-level barriers. Historical barriers constructed before 1970 generally do not meet modern requirements for safety. This paper builds on ongoing previous research projects within…
Guidelines for Standardised Bridge Barrier Designs
Consistency in the design of traffic barriers for bridges has been identified as a major issue in current practice throughout Australia and New Zealand. The need for standard solutions was recognised by road jurisdictions, consultants and…
Double/Double Primerseal Inspections

This report describes inspections conducted on double/double primerseals constructed in Victoria.

It is not typical practice to use two-layer primerseals, or polymer modification in primerseals, and methods to do so are not described by Austroads…

Inspections of Sprayed Seal Trials

This report details the findings from visual inspections conducted on two Austroads sprayed seal field trials: a non-modified binders trial near Gisborne,

Initial Field Trials with Surface Wear Rig

A mobile pavement surface wear rig has been constructed, which aims to gain an improved understanding of the failure mechanisms that are particular to the pavement surfacing layer – as distinct from the structural layers – that may be caused by…

Good Practice in Reseal Programming

This report provides asset managers with practical guidance in the development and delivery of effective resealing programs. It builds on accumulated experience of previous studies and a review of sprayed seal performance throughout Australasia.

Effects of Hot Storage on Polymer Modified Binder Properties and Field Performance

Polymer modified binders (PMBs) are increasingly used in road construction as they provide enhanced performance properties compared with conventional bitumen. Even though PMBs show enhanced service properties, they may show degradation or changes in…

Post-ageing Characterisation of Sprayed Sealing Binders: A Laboratory Study

This report presents the results of a laboratory study that was conducted as part of the development of a new-long term ageing (durability) test for bituminous binders used in sprayed seals in Australia.

Among the number of test methods reviewed and…

Cemented Materials Characterisation: Final Report
This report brings together five years of research into the modulus, strength fatigue characteristics of cement treated granular materials as used in road pavements. Laboratory procedures used to prepare, cure and test materials for flexural modulus,…
Framework for the Revision of Austroads Design Procedures for Pavements Containing Cemented Materials

The laboratory characterisation of cemented materials for road pavements was completed in Austroads Project TT1359 Cost-Effective Structural Treatments for Rural Highwaysand more recently in Austroads Project TT1664 Cemented Materials…
