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 documents the results of an Austroads project to identify the asset management needs and level of service (LOS) requirements of future non-freight road users.
Preliminary work documented the relationship of this project to other Austroads…
This report describes the results obtained during the second year of work (2015–16) into the development of a binder test that can rank the low temperature cracking performance of PMBs.
Studies conducted during the first year of work (2014–15)…
This report documents the outcomes of surveys of road freight drivers, operators and road infrastructure managers to better understand their asset management level of service (LOS) requirements.
The survey responses identified three primary road…
This proof of concept study used the data condensation technology of stochastic information packets (SIPs) in MS Excel to allow complete storage of all collected data. This approach, when connected to a pavement management system (PMS), was able to…
The current Australian polymer modified binder (PMB) specification includes low temperature stiffness tests but does not include a binder test which ranks the resistance of PMBs to low temperature cracking on the road. This study investigated…
This report presents the results of a field validation 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.
The field validation study of the new…
