However, the construction of roads and highways involves construction of various natural resources like, aggregate, bitumen etc. which are used in large quantities. The demand for the raw material for roads construction is depleting availability of these natural resources and degrading our environment. Now-a-days, various alterative/ non-conventional techniques and materials are used in road construction to reduce the impacts of road construction on environment and natural resources. Use of recycled materials from road construction is one such sustainable method, which is widely used in road construction. In the present paper, use of recycled material obtained from roads repair/ up-gradation and other alternate materials and techniques, which can be used in road construction, have been briefly discussed.</span>
