摘　　要：针对提出的沥青混凝土路面坑槽修补新方法——静力热压法 ,根据朗肯土压力理论和流变学理论 ,分析了在静力热压条件下高温热沥青混合料剪切流变密实的机理 ,同时建立了高温热沥青混合料的流变模型 ,并通过坑槽修补密实性验证试验 。In relation to new repair method for potholes in asphalt concrete pavements, namely static hot rolling method, on the basis of Rankine soil pressure theories and rheological theories, a deepening analysis is offered to the shear rheological compacting mechanism of hot asphalt mixtures under the static hot rolling, and the rheological model of hot asphalt mixtures is established. Through compactness verification experiment, the feasibility and adaptability of the new repair method are proved.
