Abstract:
Transportation plays an important role in the rapid economic development of a nation.
Transportation increases the quality and variety of consumer goods, thereby stimulating the
demand and development of trade and economy of the nation. Transport provides various
employment opportunities and boosts up the economy of the country. Roads make a crucial
contribution to economic development and growth and bring important social benefits. They are
of vital importance in order to make a nation grow and develop. In addition, providing access to
employment, social, health, and education services make a road network crucial in fighting against
poverty. Roads open up more areas and stimulate economic and social development. Every year
more and more roads are being constructed which needs a huge collection of bitumen. The primary
objective of this thesis is to Comparison on Specific gravity, Ductility, Softening Point, of bitumen
modified by waste plastic, crumb rubber & polymer. Comparison of Optimum binder content on
each case of modification. Environmental impact assessment for each case. Recommendation for
the best modifier of Bitumen Among these three materials. The data of the previous research are
collected to determine the best modifiers of bitumen. Finally, considering the optimum point, we
recommend the best bituminous modifier for decreasing the cost and quality improvement of
bitumen.
