Effects of wide centre line treatment on pavements: Y1 & Y2 2015/16 & 2016/17
In the last two-to-three years, the Queensland Department of Transport and Main Roads (the Department) has trialled and implemented the Wide Centre Line Treatment (WCLT) program to reduce the risk of head-on crashes. WCLT guidelines were developed and the Department issued an interim Technical Note TN155 in November 2015.The aim of the first part of this study was to establish the status of WCLTs on the road network and identify whether any significant pavement issues have been caused by their implementation. The Department also requested that the study establish heavy vehicle wheel path distributions in varying line-marking conditions for both WCLT and nonWCLT sections (i.e. single-line median). The second part of the study investigated the wheel paths of heavy vehicles along both WCLT and non-WCLT linemarked road sections. The study has also identified a portable, cost-effective and accurate method to track the wheel paths of heavy vehicles when travelling on WCLT and non-WCLT sections of the road network. Some recommended updates to TN155 are provided, including a requirement to undertake a pavement due diligence investigation before implementing a treatment on a particular section of road. Future research should expand the number of test sites and testing techniques to ascertain the influence of these factors in a more controlled manner.
