摘要

本研究旨在對於剛性路面用之低水泥漿量常重混凝土與透水混凝土進行加速磨耗與抗滑性能的評估。研究成果指出在加速磨耗於平版試體的磨耗終端15萬轉時，常重與透水混凝土之平均紋理深度分別下降8.3%以及15.6%、英式擺錘值分別下降18.5以及6.7%，動摩擦係數部分則分別下降16.7%以及4.4%；當試體表面出現水膜高度3 mm時，常重與透水混凝土之英式擺錘值分別下降29.5%以及16.0%；當試體表面出現水膜高度5 mm時，常重與透水混凝土之動摩擦係數的試驗將下降至多53.3%以及22.9%；值得一提的是，透水混凝土不論在何種狀況下，均比常重混凝土試體呈現較高的抗滑能力。

The research objective was to assess the accelerated polishing and skid resistance of the slabs consisted of pervious concrete and lean Ordinary Portland Cement concrete that can be designed for the rigid pavement. The research outcomes indicate that after 15 K accelerated polishing rounds, BPN_(20) of OPC and pervious concrete slabs decreased by 18.5% and 6.7%, and DFT_(20) of OPC and pervious concrete slabs reduced by 16.7 and 4.4%, respectively; in addition, when 3-mm of thin film moisture introduced to the surface of slabs, BPN_(20) of OPC and pervious concrete slabs decreased more by 29.5% and 16.0%; moreover, when 5-mm of thin film moisture presented to the surface of slabs, and DFT_(20) of OPC and pervious concrete slabs also reduced more by 53.3% and 22.9%, respectively. It is worthy of noting that the skid resistance of previous concrete slabs in every testing conditions were higher than that of OPC slabs.
