Results We can learn the relation of asphalt and the wall rock, the asphalt's cause of formation, the time of forming the asphalt, the process of forming the asphalt. 结果:让我们清楚的了解到沥青脉与围岩的关系,沥青脉的成因、形成时期、形成过程。
Research on High Modulus Asphalt and Its Mixture Modified by Rock Asphalt 岩沥青改性高模量沥青及其混合料的研究
Modified asphalt was successfully prepared based on AH-70 bitumen with native rock asphalt modifier, and favorable performance was obtained. 利用天然岩沥青作改性剂,对AH-70基质沥青进行改性,获得了良好的试验效果。
Triaxial Creep Test Study on Asphalt Concrete in the Core-Wall of Earth-Rock Dam 土石坝心墙沥青混凝土三轴蠕变试验研究
Applying Placement Asphalt Concrete Core Wall in rock-filled Dam 浇筑式沥青混凝土心墙在堆石坝上的应用
The pavement structure combination had certain effect on thermal stress in asphalt pavement. In a word, to set a graded crushed rock layer can effectively reduce the thermal stress of asphalt surface course. 路面结构组合对沥青面层温度应力也有一定程度的影响,总体来说,设置级配碎石过渡层可以降低沥青面层的温度应力。
