As part of Perth’s new Smart Freeways project, long-lever (between 16-22 m) cantilever sign structures were constructed and installed in along the northbound carriageway of the Kwinana Freeway. Due to limited stock of steel circular…

Maintaining Western Australia’s vast road network to provide a consistent level of service is a complex and costly exercise. Depending on several factors not limited to design, materials, construction, traffic and environment, pavements will consume…

Granular materials used in the design and construction of pavement base and subbase layers are often assessed for suitability based on the California Bearing Ratio (CBR) value. This measure provides an indication of the load…

Current waste management challenges across the world have required governments to develop innovative policies that target the implementation of single-use materials throughout the economy. Sustainable materials and construction practices are the future of road infrastructure…

The Western Australian road network still contains many timber bridges comprising Jarrah and Wandoo piles that have been in operation for more than 60 years. Despite their age, these structures are typically sound apart from…

With the intention of reducing Western Australia’s reliance on non-renewable resources, there has been an increased focus on identifying high-value applications for using recycled waste materials within civil infrastructure applications. WARRIP will investigate two materials,…

As new technology is trialled and rolled out there is a need to determine how recyclable these materials are. Crumb Rubber Modified (CRM) bitumen is gaining momentum and WARRIP is investigating the recyclability of asphalt…

Nanotechnology is a new innovative approach in science and engineering.  This approach is where nano-sized particles can be developed and utilised to create or manipulate the properties of materials. In pavements we hope to find…

In the world of road network construction, finding materials that are robust enough to cope with larger volumes of traffic and heavier vehicles is vital. Our roads need to perform for many years without cracking,…

ARRB, Main Roads Western Australia, WALGA, Curtin University and the University of WA developed the concept for a Western Australian Pavement Asset Research Centre (WAPARC). The purpose of the centre was two-fold.  The first objective…
