This report details investigations that were conducted to verify the new Austroads sprayed seal design guidelines.

To verify the appropriateness of the proposed basic voids factor (Vf), and the initial sealing design approach (and also to validate…

This report describes research into development of a laboratory sprayed seal binder cracking test which can be used to measure the relative fatigue cracking resistance of thin binder films which have thicknesses comparable to the thicknesses of the…

This report presents the findings of Austroads Project AT1540 Understanding the impact on pavement surfaces from next generation freight vehicles and developing practical network prediction models and responses. The main purpose of the project was…

This report examines the capacity of the extra-large wheel-tracking laboratory test method to predict the in-service performance of granular materials.

Rutting is a common distress mode of unbound granular bases under thin bituminous surfacings.

Five…

EME2 mixes are produced using a hard paving grade bitumen applied at a high binder content (approximately 6%). Compared to conventional asphalt bases with unmodified binders, EME2 asphalt is characterised by high stiffness, high durability, superior…

This report provides a summary of activities completed during 2015–16 for the Austroads long term pavement performance monitoring project.

Austroads has funded the long-term pavement performance study since late 1994. The project monitors the…

This study sought to extend the understanding of pavement works effects (WE) by extending the scope of WE treatments and evaluation measures previously used.

The study was based on data extracted from Austroads long?term pavement performance (LTPP)…

Roads and Maritime Services of NSW (RMS) design, accept and manage barriers for use on classified roads and bridges. Crash testing of a system of barrier units is infrequently performed due to high costs and a myriad of impact conditions that needs…

When adopting the European Standard for road restraint systems EN1317, France faced the need to adapt its National Guidelines in order to allow anti-falling load systems to be qualified and used on its territory. The original French bridge parapets…

The need for higher performance bridge barriers has been reflected in changes in barrier
