中文摘要 | 一般相信由配合設計以及材料的選擇方面著手.可以減少車轍的發生。傳統的馬 歇爾配合設計,對於瀝青混凝土諸多性質,特別是潛在的抗剪能力,仍無法有效的預測及評 估;且馬歇爾設備所夯壓的試體與現地鑽心試體性質問的差異頗大。過去的研究顯示,運用 旋轉式試驗儀(Gyratory Testing Machine, GTM)在瀝青混凝土的設計,對於材料抗剪能 力的評估有不錯的成效;且由於GTM壓實試體時同時有剪力及壓力的作用,就力學觀點而言, 較符合實際路面受壓的情況。本文即由研究成果建立一套本土化的GTM標準試驗參數,並由 試驗所得的剪力強度,評估不同等級瀝青之瀝青混凝土的抗車轍能力。 |
英文摘要 | Because of the tremendous increase of the volume of traffic in addition to the raises of axle load and truck tire pressure, the permanent deformation, i.e. rutting, has been a severe problem in the field of flexible pavement. Generally speaking, rutting can be reduced by the selection of materials and mix design methods. From previous experiences, traditional mix design methods, i.e., the Marshall method, can not predict or evaluate the properties of mixtures effectively, especially in the potential shear resistance. From previous studies, the Gyratory Testing Machine can be used to evaluate the shear resistance of the asphalt concrete mix. The specimen made by the GTM can be better to simulate the condition of the mixture in the field. The purpose of this research is to develop a proper testing procedure and testing parameters for GTM, and to evaluate the rutting resistance by the shear strength of asphalt concrete mixtures with different asphalts. |
