Abstract
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. In addition to repair of asphalt aggregate paved wear courses, the tiles can also be used to repair concrete wear courses with the appropriate substitution of adhesive, and if desired, reinforcing fabric.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
104 words
A method of repairing deteriorated wear course of road surfaces, comprising the steps of: a. peeling a flexible backing from a bottom of a pavement tile with the longest dimension not more than about 3 feet, b. exposing a wear course adhesive coating over the bottom of the pavement tile, c. inverting the pavement tile so that an asphalt aggregate mix layer over a top of the pavement tile faces upward, d. positioning the pavement tile above a deteriorated portion of wear course of a road surface, and e. placing the wear course adhesive coating of the pavement tile against the deteriorated wear course.
Claim 2
Independent Claim
104 words
A method of repairing deteriorated wear course of road surfaces, comprising the steps of: a. peeling a flexible backing from a bottom of a pavement tile with the longest dimension not more than about 3 feet, b. exposing a wear course adhesive coating over the bottom of the pavement tile, c. inverting the pavement tile so that an asphalt aggregate mix layer over a top of the pavement tile faces upward, d. positioning the pavement tile above a deteriorated portion of wear course of a road surface, and e. placing the wear course adhesive coating of the pavement tile against the deteriorated wear course.
Claim 3
Dependent Claim
59 words
The invention as defined in claim 1 including all of the limitations a. through e. with the addition of the following limitations: f. said pavement tile also including a section of reinforcing fabric between the asphalt aggregate mix and the wear course adhesive, g. said pavement tile further including asphalt adhesive betweent he fabric and the asphalt aggregate mix.
Claim 4
Dependent Claim
70 words

Claim 5
Independent Claim
158 words
A method of paving, comprising the steps of: a. selecting an area to be paved, b. preparing a base over the area as desired; then c. peeling a flexible backing from a bottom of a pavement tile with the longest dimension not more than about 3 feet, d. exposing a wear course adhesive coating over the bottom of the pavement tile, e. inverting the pavement tile so that an asphalt aggregate mix coating over a top of the pavement tile faces upward, f. alignming the pavement tile with respect to the area to be paved, g. placing the wear course adhesive coating of the pavement tile against the base; h. repeating the peeling step "c." through the placing step "g." above for successive pavement tiles until the area to be paved has been covered, and additionally with each repetition, i. abutting the successive pavement tile against and mated with any adjacent pavement tile already placed on the base.
Claim 6
Independent Claim
