Abstract

<p>The mix proportion of porous concrete pavement based on 1 DAY PAVE was proposed in our previous research. Furthermore, the parking lot with 4.25N/mm2 of bending strength and 0.623cm/sec permeability coefficient at 1 day of age was constructed under this mix proportion. Based on this mix proportion in this research, the porous concrete pavement with 5m width, 0.3m thickness and 20m length was constructed in the quarry where the heavy vehicle passed under the N4 traffic condition the planning traffic volume of which was 100 to 250 vehicles/day. The performance of this mix proportion for the heavy vehicles was investigated from the observation and the field permeability test in the construction field. As a result, the 3.5N/mm2 of bending strength at 1 day of age was secured because of the surface compaction method of dividing the depth direction into 3 layers. Moreover, it was confirmed that it worked sufficiently as a porous concrete pavement even if the large vehicles passed on the pavement constructed by this mix proportion.</p>
