Utilization of E-waste Plastic as Aggregate Replacement in Bituminous Concrete Mixes
In the modern era of electronic advancements, electronic waste management has emerged as a major problem for environmentalists all over the world. These advancements have discharged huge amounts of waste electronic and electrical equipment and subsequent hazardous electronic waste plastic into the environment. The present study was carried out to successfully incorporate shredded E-waste plastic as an aggregate replacement in conventional bituminous concrete (BC) mixes and to deal with various problematic issues such as depletion of natural aggregate reserves, growth of heavy axle loads on pavements, sustainability in road infrastructure as well as to handle E-waste plastic disposal. Marshall test specimens were prepared with varying bitumen percentages of 4, 5, 6 and 7% by weight of the total mix. Modified bituminous concrete mixes were prepared by using shredded E-waste plastic granules of two distinct sizes viz; 2.36 and 13.2 mm (retained IS sieve) as replacement material for fine and coarse aggregates, respectively. In case of 2.36 mm modified BC mix, maximum Marshall stability value (MSV) was achieved with 9% E-waste plastic at an optimum bitumen content (OBC) of 5.36%. Similarly, for 13.2 mm modified BC mix, maximum MSV was achieved with 3.50% E-waste plastic at an OBC of 5.26%. This study further intended to compare control and modified mixes in terms of rut depth achieved after ten thousand axle load passes using the wheel rut tester machine. In comparison to conventional BC mix, rutting susceptibility reduced by 30.62% and 21.30% for 2.36 mm and 13.2 mm modified BC mix, respectively.
