摘要
基于斜剪试验,采用正交试验方法研究了纤维用量、沥青用量和碎石覆盖率不同水平对纤维封层抗剪强度的影响。研究表明,所选三因素对抗剪强度都有显著的影响,以抗剪强度作为评价纤维封层粘结性能的指标是可行的。
Based on oblique shearing test, the influences of fiber dosage, asphalt dosage and gravel percentage of seal cover on interlayer shear strength of fiber seal were studied by orthogonal experiment. The results show that three factors have significant impact on shear strength of fiber seal, and shear strength is a feasible index to evaluate bonding properties of fiber seal.
