GROUTING AGENT FOR ROADBED MACADAM AND METHOD FOR STABILIZING ROADBED

摘要

PROBLEM TO BE SOLVED: To provide a grouting agent for preventing the scattering of roadbed macadam, keeping low viscosity and low odor throughout the year, forming a coating film having stable curability and fixing power unsusceptible to the temperature and humidity, emitting little odor and free from the problem of inflammation and toxicity and provide a method for the stabilization of roadbed by using the grouting agent.;SOLUTION: The grouting agent for roadbed macadam is composed mainly of (A) a urethane prepolymer having terminal isocyanate group and produced by reacting a polyol with an organic polyisocyanate compound and (B) a higher fatty acid ester containing hydroxy group and modified with an alkylmonocarboxylic acid as a viscosity reducing agent and has a viscosity of ≤600 mPas at 0°C.;COPYRIGHT: (C)2003,JPO
