本研究主要探討多孔隙瀝青混凝土（Porous asphalt）抵抗永久變形能力之特性。為了解材料行為並獲得試體相對應的永久變形，需運用力學模式，從潛變試驗之變形行為中區隔出有關永久變形的柔量（Compliance），進而分析不同力學模式之適用性。故本研究利用單軸動態潛變試驗來模擬實際鋪面受載重影響而產生之永久變形，並以車轍輪跡試驗求得動穩定值，兩者加以比較分析，評估多孔隙瀝青混凝土於不同試驗變因下，其發生永久變形之差異，更進一步分析多孔隙瀝青混凝土發生車轍之可能性。 This research mainly discusses permanent deformation characteristicsof porous asphalt, distinguishes the compliance of permanentdeformation from creep test by applying mechanics model, and thenanalyzes the fitting of mechanics model in order to understandbehavior of material and to get permanent deformation of sample. Inthis research, dense graded, SMA graded and Superpave graded arecontrol groups to discuss performances and mechanics behaviors.
