| dc.description.abstract | 台灣位處與亞熱帶，高溫多雨的氣候特性，易對鋪面材料強度與勁度造成損傷，進而影響鋪面之服務品質與年限，並且因重車載重能力之提供，也給予鋪面更大的損傷。
本研究採用典型國道斷面，搭配有限元素計算工具ABAQUS，並根據AASHTO 2008 暫行版「力學-經驗鋪面設計準則」進行相關車轍之模擬評估。並於模擬中導入實際溫度與實際交通量之因素，以期更能符合實際國道之車轍破壞情形。
由分析結果顯示，高溫季與高溫時段造成車轍量占全年度車轍量之53％與68％，顯示瀝青材料在高溫時之強度與勁度下降之情形，由此可知高溫亦是造成鋪面損害重要因素之一。
導入實際交通量之計算結果顯示，軸重較重之T4車型與交通量較高之T2車型為造成鋪面車轍損害之主要車型。

| dc.description.abstract | Situated geographically in the tropical zone, Taiwan is characterized by its humid subtropical climate which not only causes damage to the strength and stiffness of the pavement material, but also influences its service quality and service year; what’s more, the upgrading of heavy duty vehicles causes further damage to the pavement.
In this study, the rutting analysis will be proceeded based on the highway cross section with finite element analysis program “ABAQUS” and the AASHTO 2008 “Mechanics-Empirical Pavement Design Guide.”Also, the real temperature and real traffic factors are involved in the analysis, in hopes that the result conforms to the real highway rutting damage.
According to the results of analysis, the rutting which take the high temperature season and the high temperature time are of 53％ and 68％ respectively out of an entire year. Such results show that the strength and stiffness of asphalt material reduce when the temperature increases. Therefore, the high temperature is one of the important factors of rutting damage.
Judging by the results of analysis, the T4 vehicle type with heavy axle load and the T2 vehicle type with high traffic are mains vehicles types which cause the rutting damage to the pavement.
