RESIN MORTAR COMPOSITION AND PAVEMENT STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a resin mortar composition capable of enhancing durability and of shortening a road closing time in construction of a pavement structure by shortening a hardening time even at a low temperature, and the pavement structure using the same.

SOLUTION: A resin mortar composition is formed by mixing aggregate with an average grain diameter of 0.8-1.0 mm with a moisture-curable one-component hardening polyurethane resin binder containing a polyisocyanate compound. The aggregate, which is formed from iron and steel slag, presents a grain size distribution based on an effective grain size of 0.5-0.7 mm, a uniformity coefficient Uc of 1.3-4.0 and a curvature coefficient Cg of 0.6-2.7.
