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.

This method describes the procedure for the laboratory determination of the resilient modulus of test cylinders of foamed bitumen stabilised mixes using repeat load indirect tensile techniques.

This method describes the procedure for adding foamed bitumen to a granular material to produce foamed bitumen stabilised material. The method is applicable to materials with a maximum nominal particle size of 40 mm (i.e. 100% passing the 37.5 mm…

This method describes the procedure for compacting cylindrical test specimens suitable for use in the determination of physical properties. The method is applicable to materials with a maximum nominal particle size of 40 mm (i.e. 100% passing the 37.…

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.

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…

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…
