采用单轴贯入试验来评价沥青混合料的抗剪强度,并结合无侧限抗压强度来得到混合料的黏聚力和内摩阻角。针对不同最大粒径不同结构类型混合料、相同最大粒径不同级配、当量软化点、集料类型、沥青用量等影响沥青混合料抗剪强度的影响因素进行研究,得出当集料、沥青种类不变时,公称尺寸越大,沥青混合料的抗剪强度越大等重要结论。
The uniaxial penetration test was used to evaluate the shear strength of asphalt mixture and the unconfined compressive strength to get the cohesion and internal friction angle of the mixture. Based on the study of the influencing factors on the shear strength of asphalt mixture of different structure types with different maximum particle size, the same maximum particle size and different gradation, equivalent softening point, aggregate type and asphalt dosage, When the type is constant, the larger the nominal size, the greater the shear strength of asphalt mixture and other important conclusions.
