PAVEMENT OVERLAY: SAVINGS IN REDUCED MAINTENANCE

A non-woven reinforcing fabric was used recently in reconstructing a runway at Naples Municipal Airport. The non-woven polypropylene filter fabric provides a stress barrier that increases fatigue life of the pavement and reduces reflective cracking. After filling the cracks in the pavement, the surface was cleaned with a power broom and a tack coat of asphalt cement was applied. The fabric was overlapped with a 10-inch overlap and an extra tack coat was applied to bond overlapping layers of fabric. A course of bituminous asphalt was laid down after the fabric. A tack coat was then applied before the final course of a specially designed asphalt mix.
