Abstract : A major threat to the environment is the disposal of abundant toxic and nondegradable waste materials. Many of these waste materials can be properly regulated in construction industry by either reusing or recycling. There are a lot of landfills that have huge quantity of E-waste and plastics in it. As of now, we still do not have a proper solution for disposing electronic and plastic waste which are highly toxic in nature. This paper presents an experimental investigation on flexible pavement with partial replacements of coarse aggregate using E-waste and bitumen with recycled HIPS (High impact polystyrene). We have implemented recycled poly-styrene in molten state as a partial replacement to bitumen. E-wastes are toxic, because of the presence of multiple chemicals such as lead, bromine, chromium etc., E-waste which is in the form of PC boards are crushed to a nominal size of 20 mm are used to replace coarse aggregates. Various percentages of replacements of E-waste and HIPS are done with the coarse aggregate and bitumen. Initially the optimum bitumen percentage is calculated based on the properties of aggregates. With the ratio of bitumen, the quantity of aggregates are defined, a control mix is casted, and then the substitutions are made with HIPS and E-waste respectively. All the samples are tested for its stability using Marshall Stability test and the results are analyzed. The basic idea of this research is to effectively makeuse of these non-degradable and toxic waste materials in pavement construction, which in turn makes it economical and eco-friendly.
