摘要
鉴于沥青混合料的压实机理复杂、影响因素众多等特点,本文采用离散单元的方法,在不同作业参数下,对沥青路面碾压的过程进行数值模拟,并对压实的响应进行分析。从而寻求最佳的施工工艺和使用性能,为路面压实施工提供必要的理论依据。
Considering the complicacy of compaction mechanism and variety of construction factors, some compaction tests of asphalt pavement in different conditions are simulated with discrete element method. Then the compaction effects are analyzed, which is helpful to obtain better construction technologies. The research of this paper can provide a theoretical basis for pavement compaction.
