International experience has shown that crumb rubber-modified gap graded asphalt can provide improved resistance to crack reflection compared to conventional asphalt mixes.
Over the last decade, Intelligent compaction (IC) technology has gained popularity around the world and has been shown to improve construction quality and productivity.
TMR had developed a Pavement Risk Score (PRS) to reflect the risk to pavement preservation/failure and safety
It has long been recognised that congestion causes significant economic costs on a city, but there has not been an effort to estimate these costs across travel modes.
As the primary north-south route in Queensland, the Bruce Highway performs a critical freight and movement task, but has been consistently one of the most dangerous roads in the nation.
The WhichBridge algorithm is a qualitative risk management tool that is used to benchmark network performance and assist in the prioritisation of bridge and culvert.
There are over 1,900 transversely stressed deck unit bridges on the TMR network. This family of bridges is unique in its design and performance with a low level of transverse post-tensioning.
Granular layers underneath sprayed seal, asphalt or concrete surfacings can be highly susceptible to moisture induced damage. If the degree of saturation (DoS) is not controlled, premature failures may occur.
End-of-life vehicle tyres are a potentially valuable resource for recycling. However, at present, most tyres in Queensland end up in landfill, are dumped, or are exported overseas.
Enrobé à Module Élevé (EME), or high modulus asphalt, was developed in France in the late 1980s in response to the need to build stronger and longer lasting pavements.
