浅析试验参数对沥青混合料抗剪性能的影响

Analysis on the influence of the experimental parameters on the shear performance of the asphalt mixture

利用直接剪切试验结合无侧限抗压试验和劈裂试验对沥青混合料的抗剪性能进行了研究。结果表明,C值随沥青用量的增加而先增加后减小,值随沥青用量的增加而减小,随着温度的升高,混合料的抗剪强度降低,C值和值也随之减小。

The paper makes research on the shear performance of the asphalt mixture by direct shear experiment combining with the unconfined compressive experiment and the split experiment.The result indicates that C value first increases then decreases with the increasing of the asphalt content,while  value decreases with the increasing of the asphalt content,and with the increasing of the temperature,the shear performance of the mixture decreases with the decreasing C and  value.
