In fact, one average-sized roof recycled into road mix makes about 200 feet of a two-lane highway.
Just about everybody knows when it starts raining in your family room, it’s probably time for a new roof. However, not everybody knows what can be done with those roof shingles once they come off your house. Turns out, the roof over your house and the road in front of it have a lot in common. Both are held together with asphalt cement, a petroleum based binder. Shingles can contain between 20% and 36% asphalt cement which is used to bind a number of other materials such as fine aggregate, granular aggregate and fiberglass or organic felt to hold the shingles together. This is synonymous with a roadway surface, where asphalt cement is used to bind together blends of aggregate to form a cohesive road structure.
