Development of Improved Dense Graded Bituminous Macadam with Low Density polyethylene and High Density Polyethylene with Zykotherm Intermixing

Abstract

The utilisation of leftover polythene in flexible road constructions is discussed in this paper. In flexible pavements, recovered polymer debris such as carry bags from supermarkets and water bottles, coldrink bottles (LDPE) and plastic bottle caps (HDPE) have been utilised as additives. We'll also use a fixed amount of Zykotherm in this experiment (ZycoTherm is an odourless ingredient that boosts moisture tolerance while decreasing blending and compaction temperatures by up to 65°F). The aforementioned components were chosen for two reasons: to use economically and environmentally undesirable trash and to build a superior material mixture to withstand higher traffic loads, temperature effects, and pressure, which results in fractures in the pavement surface. The polymer debris will be processed and reduced into a size that would flow through a 2-3mm filter in the research study utilizing a shredding machine.

In this investigation, a Dense Bituminous Macadam (DBM) mixture is being presented to be prepared utilizing pure bitumen as a control sample and bitumen blended with LDPE 2 percent and 4 percent & HDPE 2 percent, 3 percent, 4 percent, 5 percent by weight, with a specific amount of Zykotherm of 1.5 percent by weight. On control and modified DBM mixes, the Marshall Stability Test, Penetration Test, and Softening Point Test were performed.
