Use of Waste Plastic in Pavement Construction

TARGET GROUP: PAVEMENT USERS

OBJECTIVES

·     To efficiently utilize the waste plastic in constructive way so that it can be beneficial to society by Marshal method of mix design and comparing it with conventional Bituminous Concrete Mix evaluating the Marshal stability, Flow value and volumetric properties bituminous Concrete (BC) Mix by Marshal method of mix design.        

SUMMARY

Use of plastic along with the bitumen in construction of roads not only increases it’s life and smoothness but also makes it economically sound and environment friendly. Plastic waste is used as modifier of bitumen to improve some of bitumen properties roads that are constructed using plastic waste known as plastic roads and are found to perform better compared to those constructed with conventional bitumen. Further it has been found that such roads were not subjected to stripping when come in contact with water. In this paper the use of higher percentage of plastic waste reduces the need of bitumen by 10%. It also increases the strength and performance of the road. Plastic increases the melting point of bitumen and hence mixing can be done in more better and easier way. Plastic waste replaces 10% to 15% of bitumen. Inclusion of plastic waste in road construction eliminates the plastic shrinkage cracking of road surface and reduces the drying shrinkage to some extent.
