Experimental Study on the Use of Waste Material (Coconut Coir and Plastic) in Flexible Pavement

Abstract

The most commonly used pavement in India is flexible pavement but over the years it is observed that the conventional mix has some drawbacks such as potholes, rutting etc., and these are becoming a major problem so to solve this problem, there is a need to develop modified mix which will have some new material in it so as to improve the conventional mix. In the present study, a modified conventional mixed is prepared with the use of materials like coconut fibre and shredded plastic where coconut fibre of
length 12mm, 14mm, 16mm, 18mm are used and 0.4 %, 0.6 %, 0.8 % by weight of mix and shredded plastic at 8% by weight of bitumen have been used. Some tests on aggregate and bitumen are performed such as Los Angeles abrasion test, impact value test, flash fire point test, penetration, ductility, and soft ball point test. The aggregate used in the study are in accordance with the Morth table i.e. grade -1 .On performing Marshall stability test it is found that optimum bitumen content is 5.25 % , optimum fibre length of 16.5 mm and optimum plastic content is 8%.
