Brief description Some 95% of 900,000 kms roads in Australia are made of unbound granular materials. Majority of these roads have aged significantly and traffic loads and frequency have increased markedly. Road stabilisation by in-situ recycling of old pavement materials using cementitious additives is commonly used as an option with lower environment footprint. The main failure mode of stabilised pavements is by fatigue cracking. Unfortunately, current design methods against fatigue cracking are unsatisfactory and do not take into account key operational factors. This project intends to undertake a bottom-up scientific study to significantly advance the design methods and associated testing of these pavements potentially leading to large cost savings.
