<p>PROBLEM TO BE SOLVED: To provide an asphalt road reinforcement embedded mesh sheet that is a reinforcing mesh sheet of a new asphalt paving layer, and is superior in adhesion with asphalt in laying and facilitates peeling removal in the repair of an old asphalt paving layer, and to provide a mesh sheet for partial repair.SOLUTION: In a net-like flexible complex constituted by using a coarse fabric as a base fabric and a reactive adhesive resin layer to cover the entire surface and having a large number of gaps of substantially quadrangle or substantially triangle, the reactive adhesive resin layer is mainly constituted of a cross-linked acrylic acid resin. A heat reactive urethane prepolymer is contained by 3-15 mass% with respect to the amount of the cross-linked acrylic acid resin. The heat reactive urethane prepolymer contains a non-reactive isocyanate group in a molecular structure at a normal temperature. Further, a normal temperature non-reactive isocyanate group is obtained by adding a thermally dissociative organic compound to the isocyanate group.</p> |
