采用马歇尔试验、间接抗拉强度试验和回弹模量试验对添加改性水库淤泥的热拌沥青混合料的路用性能进行试验研究。试验结果表明：将淤泥用于热拌沥青混合料具有一定的可行性，添加改性水库淤泥后，沥青混合料的稳定度有所提升，改性水库淤泥掺加比例越大，流值下降越多；对于添加改性水库淤泥的沥青混合料而言，未添加淤泥时其间接抗拉强度值最大，添加淤泥后其间接抗拉强度有所减小；随着改性水库淤泥添加量的增加，沥青混合料的回弹模量上升趋势显著。
採用馬歇爾試驗、間接抗拉彊度試驗和迴彈模量試驗對添加改性水庫淤泥的熱拌瀝青混閤料的路用性能進行試驗研究。試驗結果錶明：將淤泥用于熱拌瀝青混閤料具有一定的可行性，添加改性水庫淤泥後，瀝青混閤料的穩定度有所提升，改性水庫淤泥摻加比例越大，流值下降越多；對于添加改性水庫淤泥的瀝青混閤料而言，未添加淤泥時其間接抗拉彊度值最大，添加淤泥後其間接抗拉彊度有所減小；隨著改性水庫淤泥添加量的增加，瀝青混閤料的迴彈模量上升趨勢顯著。

This paper carries out experimental study on road performance of hot mixed asphalt mixture added with modified reservoir sludge by means of Marshall's test,indirect tensile strength test and elastic modulus test.The test results show that application of sludge in hot mixed asphalt mixture is certainly feasible,after addition of modified reservoir sludge,the stability of asphalt mixture improves,the higher proportion of admixture of modified reservoir sludge,the more the flow value reduces;for asphalt mixture added with modified reservoir sludge,its indirect tensile strength value before addition of sludge is maximal and decreases after addition of sludge;with increase of volume of addition of modified reservoir sludge,the elastic modulus of asphalt mixture exhibits significant rising trend.
