Abstract:
An automated process for manufacturing rubber paving blocks uses crumb rubber recovered from used automotive tires. A production line in which the molds are emptied of the formed rubber paving block and then filled with a fresh crumb rubber mixture is balanced with an oven line in which the compressed crumb rubber mixture is heated, cured and cooled before being returned to the production line for further processing. The mold includes a lid having latching mechanisms that are actuated by compressed air. The formed rubber paving block is removed from the cooled mold through a compressed air extraction mechanism so that the formed block is not damaged during the extraction process. The rubber paving block is formed with a textured bottom surface having a central depressed disk and a plurality of grooves forming interconnected passageways for water to pass beneath the blocks when installed.
