Abstract
A method of repairing a paved surface utilizes a nonwoven or woven fibrous mat made from fibers including polymer fibers, the polymer fibers having a melting point greater than about 320° F. (160° C.). The mat has a load-elongation behavior such that when the mat is subject to tensile stress, the mat achieves at least 90% of its ultimate load at an elongation not greater than 5% of the specimen length in the direction of applied stress. Another mat comprises a nonwoven or woven fibrous mat made from fibers selected from the group consisting of mineral fibers, polymer fibers, natural fibers, and mixtures thereof, and a rubbery binder. Another mat comprises a nonwoven or woven fibrous mat made from a blend of high melt polymer fibers having a melting point of at least 350° F. (177° C.) and low melt polymer fibers having a melting point of less than 350° F. (177° C.).
