Recycling Bitumen from Dismantled Road-A Case Study
Cost of construction of bituminous concrete layer of 100 meter length, 7.5 meter wide and 4 cm thick (quantity 30 m3) is Rs 246780 only, while recycled dismantled road cost is Rs 74893. Thus a saving of around 70% is observed in cost incurred when recycled bitumen is used as a partial substitute of fresh concrete.
