Traditionally roads have been constructed using the best available hard rock or gravel resources. These resources are non renewable and greater consideration should be given as to how they are used. The process of insitu stabilisation is one opportunity to assist in conserving these valuable resources. It is time that the environmental benefits of this process are considered along with, or in fact ahead of the economic benefits. South East Asia is now experiencing the engineering benefits of technology developed by countries such as Australia and America, in the use of insitu stabilisation as a form of road construction. By using this technology government and industry can look beyond the immediate cheapest solution and adopt strategies to protect our limited material resources and plan a path towards sustainable development. This paper introduces the environmental benefits of insitu stabilisation which include reductions in truck movements, savings of natural resources, fuel savings and reduced construction times and suggests some strategies which may assist reaching a sustainable future.
