Abstract
In a method of reinforcing and waterproofing a paved surface, a layer of liquefied asphalt is applied on a paved surface. A reinforcement mat is applied over the liquefied asphalt. The reinforcement mat is a nonwoven mat produced from fibers having a melting point above about 320° F. (160° C.), and selected from mineral fibers such as glass fibers, polymer fibers, or mixtures thereof. The liquefied asphalt penetrates and soaks the reinforcement mat to form a water barrier. A layer of paving material is applied over the reinforcement mat.
