RMS QA Specification R83 “Concrete Pavement Base” has recently been released following a significant review of the earlier version. This revised specification now includes the “CRCP” specifications, so R84 has been withdrawn.
The new R83-E3-R0 can be found on the RMS website at http://www.rms.nsw.gov.au/doingbusinesswithus/specifications/index.html?dlid=roadspecs
The recently released R83 Specification is attached below. This is the version released in November 2013. Readers should check the RMS website for later versions.
