HIGH-POROUS ASPHALT PAVEMENT USING HEATING CONCRETE WHICH HAS PERFORMANCE OF MELTING AND THAWING

摘要

PURPOSE: A high-porous concrete pavement using the heating concrete which has the performance of melting and thawing is provided to melt and thaw the snow and ice, and facilitate the maintenance, management and repair, and prevent the reduction of ground water and land subsidence. CONSTITUTION: A construction method for high-porous concrete paved road comprises the steps of; making an underground floor even, and forming a gravel layer(4) on a foundation of the floor so that water is easily absorbed into underground; installing a heating concrete rod(2), which is made of cement mortar or concrete composite, on the gravel layer(4) at regular intervals(50-100cm); placing insulated electric wires at the edge of a road, and connecting to an electrical rod to supply electricity to the electrical rod, and covering a connected part with an insulated tube or a plastic case to prevent electrical shock by water; paving the high-porous concrete(1) on the heating concrete and hardening, after that, making even by a compacting rod or a compacting roller; curing with plastic sheets or sponge mats; and masking and coloring, and then testing the permeability of the high-porous concrete(1) and the electrical heating performance of the heating concrete rod(2).
