Plastic use in road construction is not new. It is already
in use as PVC or HDPE pipe mat crossings built by
cabling together PVC (polyvinyl chloride) or HDPE
(high-density poly-ethylene) pipes to form plastic
mats. The plastic roads include transition mats to ease
the passage of tyres up to and down from the crossing.
Both options help protect wetland haul roads from
rutting by distributing the load across the surface. But
the use of plastic-waste has been a concern for scientists
and engineers for a quite long time. Recent studies in
this direction have shown some hope in terms of using
plastic-waste in road construction i.e., Plastic roads.
A Bangalore-based firm and a team of engineers from
R. V. College of Engineering, Bangalore, have developed
a way of using plastic waste for road construction. An
initial study was conducted in 1997 by the team to test
for strength and durability. Plastic roads mainly use
plastic carry-bags, disposable cups and PET bottles
that are collected from garbage dumps as an important
ingredient of the construction material. When mixed
with hot bitumen,
