Evaluation of the effectiveness of fabric reinforcement in extending the in-service life of bituminous concrete overlays

Tests of fabric and non-fabric treated overlays of a jointed unreinforced portland cement concrete pavement on US 70 in Orange County, North Carolina are described. Four continuous fabric and four strip fabric treatments were used in addition to four non-fabric treatments, one of which was the regular two inch 1-2 overlay used for control. The fabrics were three woven or non-woven polymeric materials and one woven fiberglass. The four non-fabric treatments consisted of a surface treatment type mat course, a plant mixed mat coat, an opengraded mix course laid directly on the old pavement and covered with the 1-2 mix, and the 1-2 mix used for control.
