PLASTIC ROADS – A REVOLUTIONARY IDEA
PLASTIC ROADS – A REVOLUTIONARY IDEA
INTRODUCTION
n Plastic use in road construction
is not new.
n 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.
WHAT IS PLASTIC?
n Plastics are typically polymers
of high molecular mass and may contain other substances to improve performance
and/or reduce costs. Monomers of plastic are either natural or synthetic
organic compounds.
WHAT ARE WASTE PLASTIC
ROADS?
n The roads
constructed using waste plastic, popularly known as Plastic Roads.
n The plastic
roads are found to perform better compared to those constructed with
conventional bitumen.
n When mixed with
hot bitumen, plastics melt to form an oily coat over the aggregate and the
mixture is laid on the road.
ADVANTAGES OF USING PLASTIC
IN MAKING ROADS
n Longevity.
n No cracking.
n Reduced stress
on bitumen which is not an unlimited resource either.
n Completely
eco-friendly.
n Reduced cost of
maintenance.
n Best use of
plastic waste.
n Stronger road
with increased marshal stability value.
DISADVANTAGES OF PLASTIC
ROADS
n Cleaning process: Toxics present
in the co-mingled plastic waste would start leaching.
n The components of the road, once
it has been laid, are not inert.

CONCLUSION
n The use of waste plastics for
pavement is one of the best methods for easy disposal of waste plastics.
n It is hoped that in near future
we will have strong, durable and eco-friendly roads that will relieve the earth
from all type of plastic waste.

BLUE MATCHING & WEDGE MATCHING OF CORE & CAVITY
BLUE MATCHING & WEDGE MATCHING OF CORE & CAVITY Blue matching was the final stage of assembly work. It is the process in which both the core and cavity parting surface are matched exactly to avoid plastic flow during moulding (flash free). In this process a thin film of blue was applied on any one side, either core or cavity parting lines. The tool was closed; a slight force was applied and was opened. The high spots where blue is picked up was removed either by diamond file, oilstone or by pneumatic grinders, if it was irregular parting line; otherwise the parting line levels were surface ground. This process is done till blue matches on both halves evenly. Wedge matching is a process in which wedges are ground and matched to the side cores ensuring efficient locking of side cores with the matching face and at the same time correct matching at the parting surface. ...
