MATS FOR USE IN PAVED SURFACES

摘要

A mat for use in a paved surface comprises a nonwoven or woven fibrous mat made from fibers including polymer fibers with a melting point greater than 320°F (160°C), the mat having a load-elongation behavior such that when the mat is subject to tensile stress, the mat achieves of 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 firbrous mat made from mineral, polymer, and/or natural fibers, and a rubbery binder. Another mat comprises a nonwoven or woven mat made from a blend of high melt polymer fibers and low melt polymer fibers. Another mat comprises a nonwoven fibrous mat attached to a nonwoven or woven fibrous mat and a nonstick layer.
