Experimental Studies on The Using of Plastic Waste for Dense Bituminous MACADAM

In India, most roads are constructed with flexible sidewalks, but the performance of the sidewalk depends largely on the quality and type of material used. The disposal of waste materials, including plastic water bottles, has become a serious problem and is not completely burned. That proves it is also harmful to the environment. In this study, plastic beg was used as a waste plastic material. In plastic waste chemical compositions like polyethylene, polystyrene, poly-propolyen, etc., melt at temperatures of 120 °C to 160 °C. The water bottles are made from HDPE plastic waste. In the given research, the use of plastic waste as a partial replacement of stone dust for different percentages. The plastic waste is cut and cleaned into a size that is passed through a 2.3 mm sieve. In the study, some tests were performed to check the physical properties of unmodified bitumen VG30 and natural aggregate to acknowledge their strength and which can be used in the design of the DBM mix. After performing the physical test, they prepared some mold at different percentages of 4%, 4.5%, 5%, and %.5.5% for the Marshall Stability test by Digital Marshall Apparatus. After obtaining the results of Marshall Properties, they found that the optimum content was 4.5%. After seeing the OPC, we took some percentages of plastic waste as 5%, 7%, 9%, and 12% replacement of stone dust and prepared the mold for testing. After testing the prepared mold, the results concluded that using plastic waste in pavement construction is better than preparing normal pavement. The plastic waste provided some more strength and liquefaction to the pavement surface. When the plastic was heated with aggregate and binders, it melted and created a bond with the aggregate and binders Due to the load applied on the surface, it will not crack easily and provided smooth surfaces for vehicles. This mixed design can also help green technologies provide a good surface at a low cost in rural and semi-urban areas.
