摘要:为深入研究ATB-25沥青稳定碎石混合料在沥青路面上基层的应用技术，论文首先选定了试验用的原材料及级配并通过马歇尔试验对ATB-25进行目标配合比设计，采用室内试验对ATB-25混合料的高温稳定性、低温抗裂性以及水稳定性进行了路用性能研究，并针对ATB-25沥青稳定碎石混合料从拌合开始至碾压完成后进行接缝处理等多个方面论述了ATB-25上基层的施工工艺。结果表明：ATB-25沥青稳定碎石混合料生产配合比的最佳油石比为3.7%，ATB-25沥青稳定碎石混合料具有良好的路用性能，可应用于沥青路面上基层，研究成果对于提高沥青路面结构性能、防治基层反射裂缝的产生具有重要意义。

Abstract: In order to study the application technology of ATB-25 asphalt stabilized macadam mixture on asphalt pavement in depth, this paper firstly selected the raw materials and grading of the test, and designed the target mix ratio of ATB-25 through the Marshall test. The road performance of ATB-25 mixture was studied through indoor test to determine the high temperature stability, low temperature crack resistance and water stability. In view of the ATB-25 asphalt stabilized macadam mixture, the construction technology of ATB-25 upper base is also discussed from different aspects, from the beginning of mixing to the joint treatment after the completion of rolling. The results show that the best oil-stone ratio of ATB-25 asphalt stabilized macadam mixture production ratio is 3.7%. The ATB-25 asphalt stabilized macadam mixture possesses good road performances, and can be applied to the base layer on asphalt pavement. The study result is of great significance to improve the structural performance of asphalt pavement and prevent the occurrence of reflective cracks in the base layer.
