Determining the Foaming Characteristics of Bitumen
Foaming of bitumen permits the bitumen to be evenly distributed throughout a soil or a granular material. It is critical for the bitumen to remain as viable foam for a period to enable it to be successfully blended into the host material.
Validation of Revised Austroads Sprayed Seal Design Approaches: Site Inspection

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…

Development of a Sprayed Seal Binder Cracking Test

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…

Taking Representative Samples of Bituminous Binders
This work tip provides guidance on binder sampling to ensure that consistent and reliably representative samples are obtained so that any test results: represent, as near as practicable, an average of a consignment or batch; or detect any variation…
Heavy Vehicle Horizontal Stresses and Pavement Surface Performance

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…

Improved Laboratory Characterisation of the Deformation Properties of Granular Materials

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…

Guide to Pavement Technology Part 4F: Bituminous Binders
Guide to Pavement Technology Part 4F: Bituminous Bindersprovides guidance on the use of bituminous materials in road construction and maintenance. Bituminous materials include bitumen obtained from refining crude petroleum oil and products derived…
High Modulus High Fatigue Resistance Asphalt (EME2) Technology Transfer: Final Report

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…

Long-term Ageing Resistance of Bitumen using the Pressure Ageing Vessel (PAV) and the Dynamic Shear Rheometer (DSR)
This test method sets out the procedures for the ageing treatment of bitumen samples under specific conditions using the Pressure Ageing Vessel (PAV), and also the determination of the complex viscosity of treated samples under specific conditions…
Austroads LTPP/LTPPM Study - Summary Report 2015-16

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…
