Recycling Asphalt
Asphalt or bitumen containing roofing materials and membranes can be reused in other asphalt applications such as for example road pavements where the bitumen content of the waste material may substitute freshly added bitumen to the asphalt composition and thereby the waste material in addition to being a useful filler also provides substantial savings in the overall costs in that the bitumen as such may be reused in the asphalt structure.
