摘要： PROBLEM TO BE SOLVED: To provide a method of stabilizing a ballast by using a setting agent for ballast crushed-stone, which agent has excellent low-odor-emitting and foaming supression properties and such viscosity as to be easily spreadable, and is curable in a short time even at a relatively low temperature.
SOLUTION: The setting agent for ballast crushed-stone is obtained by mixing the chief component, consisting of an isocyanate group-terminated urethane prepolymer (A) prepared by reaction between a polyol and an organic polyisocyanate compound and a viscosity reducing agent (B), with a curing agent component consisting of a catalyst (C). The method of stabilizing the road bed is that the setting agent having a viscosity of 500 cps or less at 0°C is spread over the ballast crush-stone with a sprinkling can.

摘要： PROBLEM TO BE SOLVED: To obtain a method for antiskid-treating of a covering plate and its covering plate excellent in operability and in long-term antiskid property and used for a temporary road. SOLUTION: The surface of a covering steel plate is coated with a two-part cold setting polyurethane resin in which the hardened material has more than 50 Shore D hardness without applying a primer. In this case, aggregates are scattered on the surface before the polyurethane resin is hardened and the aggregate without adhering to the polyurethane resin is removed after the polyurethane resin is hardened.

摘要： PURPOSE: To improve agglomeration strength by adding benzoic acid or aromatic monocarbonic acid and the like to a mixture of an elastic particle object and liquid Polyurethane resin at a site of execution. CONSTITUTION: A rubber product such as tire, tube, etc., made of natural rubber, polyisoprene rubber, styrene rubber, etc., is crushed to form an elastic particle object having a particle diameter of, preferably 0.1 to 20mm, more preferably 0.1 to 10mm. The elastic particle object is mixed with liquid polyurethane resin at weight ratio of, preferably 95 to 60:50 to 40, more preferably 75 to 85:15 to 25 to prepare a mixture. Furthermore, preferably 0.01 to 10 weight parts, more preferably 0.1 to 5 weight parts of benzoic acid or aromatic monocarbonic acid is added to the mixture for 100 weight parts of liquid polyurethane resin at a site of construction to spread on an asphalt concrete paved surface or a concrete surface and perform rolling compaction so as to form an elastic pavement structural body.
