摘要: A composition and method for use in the repair of a roadway are described. lower molecular weight hydroxyl terminated polyether polyol is reacted with an organic polyisocyanate presence solvents having specific gravity excess 1, catalyzed by mercury lead catalysts amounts sufficient to cause gel about thirty seconds. The reaction products pumped or poured over aggregate allowed percolate therethrough form flush repair.
