    Abstract: 台灣地區因地處亞熱帶,其特殊之氣候環境為潮濕多雨,加上重車超載情況嚴重,國內目前有許多機關已經嘗試採用特殊配比之瀝青混凝土路面,如石膠泥及多孔性瀝青混凝土來改善傳統路面於台灣特殊環境因素下衍生之各種破壞,其中石膠泥瀝青混凝土鋪面,以其高粗骨材比例與高瀝青膠泥含量之特殊配比具較佳之抗車轍能力及耐久性。而多孔性瀝青混凝土具有優良之排水功能,此外其抗剝脫及抗車轍能力仍須考量。本研究為瞭解此兩種特殊配比鋪面與傳統密級配鋪面之差異,以分析材料之力學行為為討論重點,期望做為國內使用推廣之依據及運用,並使此兩種鋪面能順利落實於國內鋪面工程,提升行車安全與服務品質。 許多專家學者利用現地之落錘式撓度儀量測得鋪面之撓度,但其間之力學分析及後續之預測分析則較少進行探討,為瞭解研發及鋪設特殊配比對實際改善台灣特殊交通環境條件下之情形,先藉由實驗室模擬材料力學行為求得破壞參數,再針對各鋪面性質進行結構及績效之模擬分析。求得鋪面在車輛荷重下之績效指標,此結果將可提供鋪面管理者了解現有鋪面之績效,並作為鋪面管理維護或加鋪之依據。本研究主要得到此分析路段之石膠泥瀝青混凝土鋪面預估之養護時機為開放交通8?9年後,而多孔性瀝青混凝土鋪面則預估為開放交通4?5年後。 This thesis aims at investigating the effects of heavy vehicles and high temperature on the distress and performance of flexible pavements in Taiwan. This research collects and analysis the pavement material which contains DAC, SMA and PA. Stone Mastic Asphalt was considered have good material to resist rut and it’s durable, and Porous Asphalt has an advantage to drain flooded fields. For the purpose to catch on the different between SMA, PA and DAC, it’s important to understand the mechanics behavior of the pavement material. To expect this two pavement material can be used to promote the safety and quality of drive a vehicle in pavement construction. Many professional scholars usually measure the pavement deflection by FWD to know the condition of the pavement. But there’s not much discussion to precede the mechanics and predict analysis of pavement material. In order to understand the situation of SMA and PA material to improve the special traffic and environment condition in Taiwan, this study is to simulate analysis which is pavement structure and performance in pavement characteristic. By using predicted index to provide management of pavement in accordance with know about the performance of the pavement. This research obtain the SMA pavement was predicted to maintain at 8 to 9 years after open to vehicular traffic. And the PA was predicted to maintain at 4 to 5 years after open to vehicular traffic.
