Title:
WATER PERMEABLE PAVED BODY AND CONSTRUCTION METHOD THEREFOR
Document Type and Number:
Japanese Patent JPH06346404
Kind Code:
A
Abstract:

PURPOSE: To obtain a paved body which is free of cracks and lack of aggregates by placing inorganic granulated aggregates which include a thermosetting resin having a specified elongation, on the ground and coating the ground with a thermosetting resin having a specified bending strength.

CONSTITUTION: Thermosetting resin A, such as epoxy resin, urethane resin, and unsaturated polyester resin whose tensile rupture elongation ranges from 100 to 500%, is mixed with inorganic granulated aggregates, such as natural stones, rushed stones, sintered ceramic particles and silica sand, thereby constituting a construction material (a). This mixing rate is so arranged that thermosetting resin A may be 2 to 15 parts by weight with 100 parts by weight of the inorganic granulated aggregates. Then, the surface of the construction material (a) is coated with epoxy resin whose bending strength exceeds 30kg/cm2 at an amount of 30 to 500g per m2. The thermosetting resin may be replaced with thermoplastic resin, such as polyethylene, polypropylene, polyvinyl chloride and acrylic resin. This construction makes it possible to obtain a water permeable pavement material which is free of cracks and lack of aggregates.
