【摘要】 大粒径沥青混合料具有很好的高温稳定性;在传统的标准车辙试验仪的基础上进行了适当改进,并试制了一种可以分别做300mm×300mm×50mm(100mm、150mm)三种厚度的试件的试模,用来研究最大公称粒径为37.5mm和31.5mm两种类型的大粒径沥青混合料的抗车辙能力。分析了大粒径沥青混合料的级配、最大粒径、空隙率和不同厚度对车辙的影响。更多还原

【Abstract】 The large-stone asphalt mixes(LSM) have good stability in high temperature; to study its (characteristics) in reducing rut depth,the authors made an improvement based on the standard rut test, and invented a specimen modules, which can produce separately 300 mm×300 mm×50 mm(or 100 mm/150 mm)rut test specimen. The authors analyzed the effects of thickness, gradation, maximum nominal (dimension) and percent air voids on the rut.更多还原
