  • Patent number: 4684288
    Abstract: A pavement tile includes a section of reinforcing geotextile fabric coated on a top side with asphalt adhesive and a layer of asphalt aggregate mix or "hot mix" over the adhesive. The asphalt aggregate mix is compacted to a desired thickness and degree of compaction. Asphalt is applied over a bottom side of the fabric, and a peelable backing applied over the asphalt. For repair of deteriorated pavement, the protective backing is simply peeled off, and the pavement tile applied over the deteriorated spot of wear course. New paved surface or large repairs can be made by simply adjoining tiles. The tiles are preferably made in batches. A large sheet is spread with the layers of asphalt adhesive and asphalt aggregate mix, and compacted. The large sheet is cut into tiles, and the asphalt and backing applied to individual tiles. The tiles are stacked in batches of six on a convenient crate with handles.
