【摘要】 透水钢渣沥青混合料路面（OGFC）既具有排水沥青混合料的透水、降噪功能，又兼具钢渣的抗滑、以及沥青间黏聚力强的特点，增强了混合料中的骨料间嵌挤力。通过不规则多面体生成技术，生成具有级配特征、特定空隙率的不规则集料颗粒。在此基础上，通过理论推导、单轴压缩试验和动态模量试验，标定出模型内部不同工况下的不同接触之间的细观接触模型的细观接触参数。为透水钢渣沥青混合料路面后续的各种复杂力学性能研究提供基础。更多还原

【Abstract】 The permeable steel slag asphalt mixture pavement(OGFC) has the function of permeability and noise reduction of drainage asphalt mixture, as well as anti-slip and strong adhesion between steel slag and asphalt, and can enhance the embedding force between aggregates in the mixture and comply with the general policy of national vigorous development of sponge cities. In this study, irregular aggregate particles with gradation characteristics and specific void ratio are generated through irregular multifaceted generation technique. On this basis, the fine contact parameters of the fine contact model between different contacts under different working conditions within the model are calibrated through theoretical derivation, uniaxial compression test and dynamic modulus test; which provides the basis for the subsequent research of various complex mechanical properties of permeable steel slag asphalt mixture pavement.更多还原
