The present study involves the recycling of existing asphalt pavement materials of a dismantled road ... conducted on asphalt concrete mixes with 30, 40, 50, and 60 percent replacement with RAP. These test results were ... 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.
Numerous studies show the potential of recycling aggregates such as ceramics, rubber [2, 3], glass, and demolition wastes (bricks and concrete). Due to the high amount of concrete from demolition wastes, this material was studied as substitution of natural aggregates by several authors [ 5 – 8 ].
