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…
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…
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…
