Design and Construction Guidelines for the use of Crushed Recycled Concrete on Local Government Roads in WA
Design and Construction Guidelines for the use of Crushed Recycled Concrete on Local Government Roads in WA
There is an increasing focus on the use of recycled materials for road building. The IPWEA/WALGA Specification for the supply of recycled road base was published in 2016 and some Local Governments have been using this material on a variety of projects. There is still some reluctance to specify crushed recycled concrete (CRC) for road basecourse, due to the perceived risk of reflective cracking and uncertainty regarding design and construction practices.
This LG TRRIP project provides guidance to inform Local Government practitioners on the appropriate design and construction practices for the use of crushed recycled concrete in Local Government road base. The practitioners’ guideline and technical report function as a complement to the WALGA / IPWEA Specification and align with the WA State Government’s Roads to Reuse Program.

Guideline for selection of seals within asphalt layers
This LG TRRIP project will develop a practical factsheet for Western Australian local governments and industry practitioners, providing clear guidance on the purpose, selection and application of seal treatments used beneath asphalt wearing surfaces.
Crumb Rubber Modified Binders in asphalt applications on Local Government roads in WA
Crumb Rubber Modified Bitumen (CRMB) incorporates recycled tyre rubber into bitumen, delivering enhanced performance and sustainability benefits. CRMB has been successfully used in Australian road networks and globally, offering improved durability and resistance to cracking.
Catalogue of Standard Pavement Profiles for Local Government roads in WA
This project provides a catalogue of pavement profiles for asphalt and sprayed seal applications for a range of traffic volumes and subgrade CBR values. Local Governments practitioners will be able to use these to select profiles for design and construction, check designs provided by external parties and reference when investigating road failures.
Considerations for Sealing Local Government Roads in WA
LG TRRIP developed an asset management practitioners’ guideline for unsealed roads from a whole of life cost basis. It provides local government practitioners with guidance regarding when an unsealed road (or specific section of road) should be sealed due to several factors, including increased traffic.
