为了研究不同温度及不同压力变化对浇注式沥青混凝土贯入度及贯入度增量的影响关系,文中以清水河大桥桥面铺装工程为依托,对最佳油石比下浇注式沥青混凝土的贯入度及其增量指标进行了深入研究。研究发现:贯入度及贯入度增量随温度、压力的增大而增大,且贯入度及其增量与温度呈现出良好的指数关系。 In order to study the influence of different temperature and different pressure changes on the penetration of pouring asphalt concrete and the increment of penetration rate, based on the bridge deck paving project of Qingshuihe Bridge, the optimal asphalt concrete pouring type asphalt concrete Penetration and its incremental indicators conducted in-depth study. The results show that the increment of penetration degree and penetration degree increase with the increase of temperature and pressure, and the penetration degree, increment and temperature show a good exponential relationship.
