Abstract
A geotextile fabric, method of manufacture and method of use, are provided. The composite geotextile fabric has a first group of uncrimped synthetic weft threads, a second group of uncrimped synthetic warp threads not interlaced with the first group, and a knit yarn stitch bonding the warp and weft threads loosely together. A nonwoven filtration fabric may also be included. The composite geotextile fabric may have a controlled extensibility, which preferably is equal to or less than the two to four percent extensibility of asphalt paving, making the fabric suitable for use in repairing cracked road surfaces and the like.
