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.
Claims6
A method of reinforcing and waterproofing a paved surface comprising the steps of:
- applying a layer of liquefied asphalt on a surface;
- forming a water barrier by applying a non-laminated reinforcement mat over the liquefied asphalt, the reinforcement mat comprising a nonwoven mat produced from a mixture of mineral fibers and polymer fibers, the fibers having a melting point above about 320° F. (160° C.) wherein the reinforcement mat is not impregnated prior to its application over the liquefied asphalt, and wherein the liquefied asphalt penetrates and soaks the reinforcement mat to form the water barrier;
- and
- applying a layer of paving material over the reinforcement mat.
