A Review on using Waste Polymer as Additive in Asphalt Mixture
Conventional bituminous material does not have the performance requirements for road construction, which are
increasingly subjected to heavy loads, heavy traffic, frequent stresses and various climactic and environmental conditions.
When the produced bituminous mixture does not meet the climate, traffic, and pavement structure requirements, to qualify as
an optimal mixture, this kind of bituminous mixture need to be modified by an attractive alternative to gain the required
properties to be able to overcome the stresses and distresses that the pavement undergoes resulting from bitumen deficiencies
in the mixture. Modification of bituminous mixtures offers one answer to overcome this problem, and thereby improve the
performance and durability of the pavement. Many studies suggested the application of polymers to bituminous mixtures to
modify it in a way to significantly enhance its performance, however, using polymer is costly. Using waste polymers, as
modifiers is one of the several ways to cut the expenses and reduce the overall cost of road pavement projects. This review
paper reported the utilization of polymer waste in asphalt pavement and the impact of using polymer waste on both of
environment and road construction.
