Road Networks

With climate change expected to have increasing impact on weather patterns, it is becoming difficult to assess the general vulnerable of the Western Australian state road network to extreme weather events. This project will build…

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…

Unexpected growth in localised industries such as mining and agriculture, has led to the rapid deterioration of roads carrying heavy vehicle traffic not anticipated during design and construction. Significant funding is required to maintain acceptable…

Assessing rut depth, roughness and surface texture with a laser profilometer makes the best use of this quick, efficient technology. In order to improve confidence in this method WARRIP reviewed the approved test methods against…

With an extensive rural network that has immense sections of road that have reduced visibility at night, WARRIP investigated some of the emerging technologies to improve visibility on regional roads. Whilst potential technologies look promising,…

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…

Across WA, temperatures vary immensely such that when designing asphalt pavements, accounting for these temperature ranges can have a large impact on pavement thickness. To better understand how to cater for the extreme heat fluctuations…

As part of Main Roads efforts for continuous improvement, industry professionals have reviewed the current Main Roads practices for contracting work. In response to issues raised, WARRIP launched an investigation to determine what could be…
