摘要
对纤维碎石封层使用材料的参数如何确定进行了探讨,通过测力延度、落球试验、粘结强度等试验,对纤维沥青的最大拉应力、最大延度、与集料的粘附性能以及抗剪切能力进行了检测,最后阐述了纤维碎石封层施工参数的设计方法,可为同类型的施工提供借鉴。
A discussion was made on how to determine the parameters of materials used in fibergravel sealing. The maximum tensile stress and ductility of fiber asphalt and the adhesion property and anti-shear ability of the aggregate were checked in terms of the force ductility test, falling sphere test and bonding strength test. The parameters design of materials for fiber-gravel sealing was expounded, which provides reference for similar projects.
