Description

 This study is new Hybrid Porous Concrete Pavement (HPCP) for reinforcing the steel plate deck.<br> Recently, for reinforcing it, mostly using Steel Fiber Reinforced Concrete (SFRC). This is because SFRC has an effect of reducing fatigue failure applicable to the steel plate deck. But, In case of paving asphalt mixture on the SFRC has many processes.(ex, placing of concrete, waterproofing, paving asphalt etc). HPCP has two kinds of performance, permeable surface texture and undersurface waterproof property. It was confirmed thixotopic workability and durability at the laboratory experimentation. Then in trial construction, It was confirmed a possibility of paving HPCP.
