Effect of waste plastics utilization on indirect tensile strength properties of semi dense bituminous concrete mixes

The steady increase in high traffic intensity in terms of commercial vehicles and significant variation in daily and seasonal temperature demand improved road characteristics, so an improvement in the property of bituminous mix is required. Today the stability of waste plastic is enormous, as the plastic materials have become part of daily life. They either get mixed with municipal solid waste or thrown over land area. If not recycled, their present disposal is either by land filling or by incineration. Both the processes have certain impact on the environment. Under these circumstances, an alternate use of the waste plastic is also needed. Thinner polyethylene carry bags are the most abundantly disposed of wastes, which do not attract rag pickers for onward recycling due to their lower value. These polyethylene bags are easily compatible with bituminous mixes at specified conditions. This paper calls for the use of plastic in bituminous concrete to get improved properties which can cater to increasing traffic intensity, for the study semi dense bituminous concrete grading 2 as per Ministry of Road Transport & Highways (MoRT&H) (IV Revision), 60/70 grade bitumen and 40 micron sized plastic were used. Aggregate and binder were checked for their suitability through various basic tests. Marshall tests, indirect tensile strength tests and degradation tests were conducted with trial waste plastic content added along with aggregates to find the influence of plastic addition to semi dense bituminous concrete mix.
