  • Patent number: 5511899
    Abstract: A roadway surface for private driveways, rural roads and farm lanes or other light traffic surfaces is made from recycled asphalt roofing shingles in pieces, preferably elongated strips, that overlie one another to form a cushioning mat. The roadway surface has a base layer of crushed aggregate such as paving stone, gravel or dirt, over which is a middle layer of shredded or particulated asphalt roofing shingle waste materials, such as reclaimed used asphalt roofing shingles and optionally new shingle tabs or other shingle production waste. The binding characteristics of the shingle pieces can be enhanced by adding a petroleum distillate such as asphalt, bitumen, paraffin, or tar. A top dressing layer of crushed aggregate such as paving stone or gravel protects and isolates the cushioning mat of shingle pieces. Each layer can be applied using conventional roadway grading equipment, preferably in layers of about one to two inches thick.
