  1. The evaluation for sidthk program shows that its backcalculation procedure is stable and its accuracy is higher, furthermore, the backcalculated results are not effected by the selection of seed value at a very wide range. the accuracy of sidthk program is much better than that of current gpr data analyzing method no matter for new or aged asphalt concrete pavement and cement concrete structure. in addition, the pavement thickness backcalculation results f

    對sidthk軟體考評結果顯示: sidthk軟體反算過程穩定,精度較高,而且反算結果在相當大范圍內不受初始值的影響;不論是對新鋪瀝青混凝土路重慶大學博士學位論文面,還是對舊瀝青混凝土路面和水泥混凝土板, sidthk軟體的反算精度都明顯高於現行方法的計算精度。
  2. The current gpr data analyzing method for pavement thickness can only give the acceptable results for new asphalt concrete pavement, but for aged asphalt concrete pavement and cement concrete pavement, the accuracy is not satisfactory because of the theoretic modeling and data acquisition difficulties. the study on pavement compaction, moisture content and asphalt content is under exploration and the program for processing gpr data based on rigorous theoretic model can not be found in literature

    由於理論模型及信號採集等方面的困難,現行路面雷達厚度分析方法僅對新鋪瀝青混凝土路面有相對較好的檢測精度,而對舊瀝青混凝土路面和水泥混凝土路面的檢測精度卻不能令人滿意,對路面其它技術指標如壓實度、含水量以及瀝青含量的研究還處于探索階段,建立在嚴密理論模型基礎上的數據分析軟體系統尚處于空白狀態。
  3. The rational evaluation system of damaged condition for aged cement pavement

    舊水泥砼路面破損狀況合理評價體系
  4. The physical and mechanical properties of the raw materials and the recycled mixture are studied respectively in this paper by means of indoor experiments. the primary mechanical indexes of the recycled mixture are tested, including the unconfined compressive strength, the resilient modulus and the cleavage strength. the changing laws of these indexes are related to the cement content, the ratio of old asphalt mixture to lime soil and the aged - period

    初步對再生混合料的無側限抗壓強度、抗壓回彈模量和劈裂強度等主要力學指標進行了分析評定,總結了其強度性能與剛度性能隨水泥劑量、舊路面與灰土比例和養生齡期的變化規律,並建立了各指標之間的相互聯系;此外對再生混合料的水穩定性、抗凍性、干縮特性、溫縮特性和疲勞特性也進行了試驗分析;在上述研究的基礎上還探討了原材料性質對再生混合料性能的影響。
