Cracking mechanism in lightly cemented materials
We're trying to further understand the cracking mechanism in lightly cemented materials in a research project ARRB is undertaking. ARRB's labs are playing a critical role in this work, as Dr James Grenfell explains:
Fatigue Characteristics of Foamed Bitumen Stabilised Materials
Negin Zhalehjoo from ARRB discusses a research project we are working on for Austroads. We are developing a procedure to evaluate the laboratory fatigue characteristics of foamed bitumen stabilised materials, and to provide a new fatigue relationship for these materials. The work is being done in ARRB's state-of-the-art research labs in Port Melbourne, Australia.
Fourier Transform Infrared Spectroscopy (FTIR) Testing
ARRB has been working to develop a new test method for the rapid characterisation of binder ages in bituminous surfacings in the field. ARRB has worked with local governments around the country, running tests of binder samples in our portable FTIR machines at our Port Melbourne laboratories. ARRB's Danielle Garton and Khulood Hwayyis explain:
Can We Recycle Crumb Rubber Modified Asphalt?
Asphalt can be recycled, and old tyres can be successfully used to build new roads. But can we recycled crumb rubber modified (CRM) asphalt? ARRB is delivering a project for Main Roads Western Australia (MRWA) aiming to ensure CRM asphalt can be used again. ARRB's Zia Rice and Jaimi Harrison talk us through the project.
New rutting performance evaluation method for bituminous binders
ARRB's Young Choi explains how we are using our labs to develop a new rutting performance evaluation method for bituminous binders.
