What is claimed is: 1. A reinforcement for asphaltic paving comprising:an open grid comprising at least two sets of substantially parallel strands, each set of strands having openings between adjacent strands and the sets being oriented at a substantial angle to one another; anda coating thoroughly impregnating the strands and disposed over said grid to surround the strands without closing the openings between the strands, said coating being activated at a paving temperature, pressure, or both, to form a bond compatible with asphaltic paving, said coating not being tacky at an ambient temperature and pressure, said coating comprising a resinous non-asphaltic material, wherein the same resinous non-asphaltic material impregnates and coats the strands, and the coating comprises:40-60 wt % pvc-acrylic latex;5-25 wt % styrene-acrylic acid latex;5-25 wt % ethylene-acrylic acid latex; and0-20 wt % internally plasticized pvc latex;0-1 wt % organic oil/silica defoamer;0-5 wt % carbon black dispersion;0-5 wt % EBS anti-blocking wax dispersion;0-10 wt % acrylic solution polymer;0-2 wt % non-ionic surfactant;0-1 wt % fluorosurfactant; and0-5 wt % polyacrylic acid thickener.
