【摘要】 透水钢渣沥青混合料路面既具有排水沥青混合料的透水和降噪功能，又兼具钢渣的抗滑、与沥青间黏聚力强的功能，且符合国家大力发展海绵城市的大政方针。为进一步分析透水钢渣沥青混合料路面的各项力学性能，本文采用颗粒流软件，通过不规则多面生成技术，生成具有级配特征、特定空隙率的不规则集料颗粒模型，并通过室内单轴压缩试验和动态模量试验，标定模型内部不同接触之间的细观接触模型的细观接触参数。本文研究成果可为透水钢渣沥青混合料路面的力学性能分析提供借鉴。更多还原

【Abstract】 The pavement of permeable steel slag asphalt compound not only has the functions of water permeability, noise reduction of drainage asphalt compound, anti-slip of steel slag and strong cohesion between asphalt, but also is in line with the national policy of vigorously developing sponge cities.In order to further analyze the mechanical properties of the pavement of permeable steel slag asphalt compound, particle flow software is used to generate an irregular aggregate particle model with gradation characteristics and specific void ratio through irregular multi-faceted generation technology, and through the indoor uniaxial compression test and dynamic modulus test, the mesocontact parameters of the mesocontact model between different contacts inside the model are calibrated.The results can provide a certain reference for the analysis of mechanical properties of permeable steel slag asphalt compound pavement.更多还原
