Waste Plastic’s Effect on the Deterioration of Bituminous Mixes in Cold Climates
Journal Title: International Journal of Trend in Scientific Research and Development - Year 2020, Vol 4, Issue 5
Abstract
The modifications in bitumen can be carried by addition of various types of additives. Polymers can be categorized as one of the types of additive. By the addition of Polymers to the bitumen, the temperature susceptibility and also the stiffness get increased. Due to this increase in stiffness, the resistance of the mix to rutting in hot climates is generally improved and thus we can use comparatively softer base bitumen, which results in improved performances at low temperatures. It was observed that after comparing the results of the mixes prepared by the addition of both Anti stripping material with Varying percentages and WPB, and the mixes containing only WPB, the latter provided better results in terms of Retained Marshall stability and Marshall Quotient. It was noticed that control mix after being subjected to repeated Freeze Thaw cycles can lose more than 50 of its original strength hence modification to the mix should be done by addition of 6 WPB which highly enhances the strength of the mix. The mixes with 6 WPB even after 7 Freeze exhibit stability values similar to that of control mix under ideal conditions.
