Effect of Coated Aggregates by Plastic Bottles on Bituminous Concrete for Road Pavement
Journal Title: International Journal of Multidisciplinary Research and Analysis - Year 2023, Vol 6, Issue 11
Abstract
The amount of waste plastics which are released by factories and human activities day to day becomes big problem to human being health as days ahead. The major impact of waste plastics is the environmental pollution, as they do not decompose. This current study, was about to use those waste plastics as Partial replacement of bitumen in bituminous concrete production for road pavement. Different materials like plastics, coarse aggregate, fine aggregate, filler materials and bitumen were used. The plastics used in this research were shredded into small pieces of 5 to 10 mm size and mixed with aggregates in hot state. Tests on aggregates and bitumen for strength and specific gravity were carried out respectively. To examine the behavior of plastics, test specimens were prepared without plastic contents with different bitumen percentage of 4.5%, 5%, 5.5%, 6%, 6.5% for the purpose of finding optimum bitumen binder for normal mix. The optimum bitumen percent for normal bituminous mix is 5.7% and the maximum stability of 9.2875 KN is reported, which is above 8.2 KN as minimum stability accepted. The quantity of bitumen was partially replaced with 3%, 10%, 15% and 20% by plastics. High stability value of 10.89 KN was found at optimum 14.3% plastics. This paper reports that waste plastics produce a good result compare to normal mix.
