Implementing the use of reclaimed asphalt pavement (RAP) in TMR registered dense grade asphalt mixes: background analysis report

Austroads published the results of a multiyear project in 2016 which provided guidance on the design and specification of asphalt mixes containing reclaimed/recycled asphalt pavement (RAP) to reduce uncertainty regarding the performance of these mixes. As part of the Austroads project, the application of the binder blend characterisation in accordance with test method AGPT/T193-2015 was validated to be used for designing the binder blend in mixes containing RAP without compromising the performance of the mix. A NACoE project was conducted around the core findings of the Austroads project which aimed at facilitating the application of higher percentages of RAP in dense graded asphalt mixes by providing approval requirements for contactors if they wished to progress from RAP approval level 1S to a higher approval level. This was provided in the form of a technical note detailing the binder blend viscosity requirements for high RAP dense graded asphalt mixes. This report documents the technical analyses and the background information that led to the development of the technical note.
