• Project Overview


Main Roads has implemented an Infrastructure Council Sustainability Assessment (ISCA) rating process that requires the quantification of greenhouse gas (GHG) reductions and sustainability benefits. The ISCA sustainability ratings tool can be used for standard pavement technologies; however, it does not have the flexibility to quantify innovative pavement designs, such as those using recycled materials – due to existing tool limitations. This project addresses this capability gap by developing a user-friendly sustainability assessment tool to enable consistent and reliable quantification and comparison of lifecycle sustainability and economic impacts of pavements.
