    Abstract: 多孔隙鋪面與傳統密級配鋪面相比具有較高的空隙率,因此有較佳的降噪特性與抗滑能力。多孔隙瀝青混凝土的成效取決於組成材料的種類與品質、混合料級配等,許多研究雖對於多孔隙瀝青混凝土組成材料與其成效有進行探討,但卻未對其成效之關連性進行討論。本研究首先針對粒料特性進行探討,分別對天然粒料與再生粒料之粒料品質、來源成分、表面性質等進行探究,根據多孔隙鋪面國家規範的要求,選取較適於多孔隙瀝青混凝土的粒料,並將上述成果彙整,以供後續工程查詢利用;以不同種類之瀝青油進行多孔隙瀝青混凝土配合設計,設計不同的孔隙率及不同厚度進行各項成效分析,彙整各種設計的抗滑及降噪成效,最後藉由因素分析尋求影響抗滑能力及減噪能力之相關因子,再以選取之因子作為材料挑選與配合設計之控制進行因子之驗證。此外,現地驗證亦是本研究重點,藉由現地數據收集利用資料採礦方式,探究平坦度、摩擦力及噪音之相關性,最後故本研究採用群體決策方法建立排水性鋪面之較適斷面。 The void of Porous Asphalt Pavement is higher than Dense, and a better capacity for noise reduction and skid resistance to Porous Asphalt Pavement.The object of this study discussed with properties of aggregate, performance of void with different type of bitumen, finding factors of capacity for noise reduction and skid resistance and proving. Besides, to explore correlation of roughness, skid resistance and noise reduced with data of onsite testing, and construct the better porous asphalt pavement section by using Hierarchy Process method. 研究期間:9908 ~ 10007
