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…
This study investigated whether the segregation propensity of a polymer modified binder (PMB) during hot storage affects its performance on the road.
The Australian PMB specification currently includes a segregation test which determines whether the…
This report presents the findings from the first year of a three year Austroads study which aims to maximise the re-use of reclaimed asphalt pavement (RAP) in new asphalt product. The objective of this first year of study is to improve the…
This report presents the results of a literature review and laboratory study which 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 literature review…
Bitumen, an important component used in road construction in Australia and New Zealand, is manufactured from a finite, non-renewable crude oil resource. A number of commercially available alternative binders and bitumen extended binders have been…
This report describes the planning and construction of Australian field trials which will measure of the relative performance of polymer modified binders (PMBs) used in strain alleviating membranes in sprayed bituminous sealing. Issues addressed in…
