Asphalt in rail for the first time in Australia

Asphalt has been formally used as an integral pavement component of a non-ballasted rail track for the first time in Australia. Railpave Asphalt was incorporated into an engineered track system on a section of heavy haul rail track in Branxton, New South Wales, Australia. The proprietary ballastless track system is the brainchild of a highly respected company specialising in railway track system design, construction and maintenance. Boral Railpave was chosen as the asphalt element of the bespoke ballastless track system. A major target was to achieve cost optimisation and make it more feasible for a wide range of applications, both: for known applications like high-speed tracks and also as an alternative to ballasted track in common lines with lower speeds. This could be achieved by applying a holistic approach during the selection and implementation of track components, materials like Railpave asphalt, as well as work methods. Railpave was used in the specialist track system installed in Australian Rail Track Corporation (ARTC)’s Hunter Valley Network with completion achieved in November 2017. During multiple shutdowns ranging between 68 hrs to 96 hrs a variety of components were installed to introduce a new track slab system. Railpave was tested in the laboratory to ensure it met or exceeded the bespoke slab track requirements which was followed by a type approval process with ARTC. The sophisticated track system is intended to provide the precision required to continuously and accurately weigh axle loads. The installation will also be instrumented to monitor rolling stock in transit and telegraph imminent maintenance needs earlier than current processes so that down time can be significantly reduced. Axle loadings of 30 tonnes are applied and the system must provide an alternative that is much more durable and stable to facilitate accurate operation of the instrumentation.
