  • 國內多孔隙瀝青混凝土(PAC),以標稱最大粒徑(Nominal Maximum Aggregate Size, NMAS)19mm為主,鋪面厚度約3~5cm;但NMAS 12.5mm之PAC鋪面之經驗較有限。本研究主要使用改質III型瀝青,配合標稱最大粒徑19mm、12.5mm及9.5mm之PAC級配,依照日本排水性瀝青混凝土配合設計進行配比,並製作試體進行實驗室工程性質試驗與績效評估,比較其耐久性、功能性及安全性。並針對PAC之抗車轍能力進行分析,以標稱最大粒徑12.5mm之PAC級配,使用三種不同黏滯度之改質III型瀝青及傳統瀝青AR80製作之車轍試體進行相關的分析。
    研究結果顯示,耐久性方面,NMAS 19mm,NMAS 12.5mm及NMAS 9.5mm級配PAC之穩定值分別為591、620及544kgf;間接張力強度分別為0.70、0.77及0.51MPa;平均回彈模數分別為2300、2352及1293MPa,顯示NMAS 19mm及NMAS 12.5mm較NMAS 9.5mm級配之PAC強度較強,有較佳的耐久性。功能性方面,NMAS 19mm,NMAS 12.5mm及NMAS 9.5mm級配PAC之滲透係數分別為0.18、0.13及0.16 cm/s,皆大於規範值0.01 cm/s十倍以上,顯示三種不同標稱最大粒徑之PAC級配皆有良好的功能性。安全性方面,NMAS 19mm,NMAS 12.5mm及NMAS 9.5mm級配PAC之BPN值分別為67、73及68;平均紋理深度分別為1.70、1.24及0.97mm,顯示PAC在安全性方面皆有一定水準,且使用較大標秤粒徑之PAC級配具有較佳的安全性。車轍輪跡試驗部分,NMAS 19mm、NMAS 12.5mm及NMAS 9.5mm級配之動穩定值分別為3150、2864及2739(次/mm),顯示使用較大標稱最大粒徑的級配有較佳的抗車轍能力。

    Porous asphalt concrete (PAC) in the country is based on nominal maximum aggregate size(NMAS) of 19mm.The thickness of 19mm NMAS PAC is about 3~5cm.In this study, engineering properties of three types of 19mm NMAS, 12.5mm NMAS and 9.5mm NMAS PAC with type III modified asphalt were evaluated by means of conventional laboratory test.Assessment is divided into durability, functionality and safety.In addition, 12.5mm NMAS PAC with three types viscosity of III modified asphalt and AR80 straight-run asphalt was carried out to assess the effect of rutting resistance.
    The result showed, in durability respect, the Marshall stability of 19mm NMAS, 12.5mm NMAS and 9.5mm NMAS PAC is 591, 620 and 544kgf respectively;Indirect tensile strength is 0.70, 0.77 and 0.51MPa respectively;Resilient modulus is 2300, 2352 and 1293MPa respectively, 19mm NMAS and 12.5mm NMAS PAC have better Strength than 9.5mm NMAS PAC.In functionality respect, the permeability coefficient of 19mm NMAS, 12.5mm NMAS and 9.5mm NMAS PAC is 0.18, 0.13 and 0.16 cm/s respectively, the result showed PAC has good functional.In safety respect, the British pendulum tester(BPN) of 19mm NMAS, 12.5mm NMAS and 9.5mm NMAS PAC is 67, 73 and 68 respectively, the result showed PAC has good safety, and PAC with larger NMAS can provide better sliding properties on the pavement. In rutting resistance respect, the dynamic stability of 19mm NMAS, 12.5mm NMAS and 9.5mm NMAS PAC is 3150, 2864 and 2739(pass/mm), the result showed PAC with larger NMAS can provide better rutting resistance.
