Abstract

Abstract: According to strength construction theory of the asphalt mixtures,the anti-sheafing strength index of the fiber asphalt mixtures-φ and c are tested by directly-sheafing test,uniaxial-compression test,indirect-tension test and uniaxial-penetration test to explore the anti-shearing ability of the fiber asphalt sand.And the susceptivity of three test methods of fiber type and dose is analyzed.

Key words: fiber, dose, asphalt sand, anti-shearing strength index

摘要： 根据沥青混凝土强度形成原理,用直接剪切、单轴压缩、间接拉伸和单轴贯入试验测试纤维沥青砂的抗剪强度指标——内摩擦角φ和黏聚力c,探讨纤维沥青砂的抗剪特性,并分析3种试验方法对纤维种类和掺量的敏感性。
