CONCRETE ROAD SURFACE PAVING MATERIAL AND JOINT MEMBER USING PULVERIZED WASTE TIRE

摘要

PROBLEM TO BE SOLVED: To provide a technique for reuse waste tires produced in great volume around the world as a concrete pavement road surface paving material.;SOLUTION: Waste tire rubber chips 2 and 3 beaten into a length of 0.1 to 50 mm or cut into a size of 0.01 to 2,500 square millimeter are used as aggregates in the concrete pavement road paving material 1 wherein the aggregate of 10 pts.wt. is mixed with concrete of 10 to 500 pts.wt. Aggregates 6 made by pulverizing the waste tire into rubber chips of 0.1 to 5 mm of 10 pts.wt. is mixed with mortar of 10 to 500 pts.wt., so as to obtain a concrete pavement joint member 7 for filling into a joint for the concrete pavement as a dry molded board. Or the aggregates 6 made by pulverizing the waste tire into the rubber chips of 0.1 to 5 mm of 10 pts.wt. is mixed with mortar of 10 to 500 pts.wt., so as to obtain a concrete pavement joint member 9 for filling into the joint of the concrete pavement by a wet construction method.;COPYRIGHT: (C)2010,JPO&INPIT
