Road infrastructure plays a crucial role in transportation and it is one of the most important factors in a country’s development. The vital role that they play in the present economy is reflected in many kilometres of roads worldwide. These roads are inherently exposed to external traffic loads, environmental loadings and geohazards which can lead to failures posing great safety concerns for road users. Pavement research team at RMIT has been working on identifying new additives for cost effective road construction using soil stabilization techniques. Number of PhD students are currently engaged in the team looking into effectiveness of novel additives for the application of road construction in collaboration with number of industry partners. Two possible additive types were identified as effective in the application to roads. The research assists to understand the mechanism of new stabilizers better, thus to derive the maximum benefits from new additive based soil stabilization. The research has great potential to expand with the TREMS by applying waste (such as glass fines, plastic, rubber, etc) into constructing sustainable roads.
