industrial and social development of India. 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
