Abstract

The present study is to carry out the use of over burnt brick aggregate along with waste plastic modified bitumen in order to minimize the aggregate shortage problem in North-Eastern region of India for the construction of roads. Marshall Method of mix design is considered for deciding the optimum bitumen content to prepare the bituminous mix with such aggregate. 1%, 3%, 6%, 8% and 10% waste plastic by weight of bitumen is added with hot bitumen. The optimum bitumen content is considered before mixing the plastic with bitumen. The stability, Indirect Tensile Strength, Tensile strength ratio, Stripping value of the mix is evaluated. The mix with 8% plastic shows higher stability (increased by 32%) and higher indirect tensile strength (increased by 65%). Tensile strength ratio also increases and it is more than 75%. There is very less stripping observed for the mix modified by 8% waste plastic.
