纤维掺量对自融雪沥青混合料路用性能的影响

Effect of fiber content on road performance of self snowmelt asphalt mixture

结合国内外研究现状,将超薄盐化自融雪沥青加铺层材料应用于高等级公路路面工程,得出现有超薄盐化自融雪沥青加铺材料存在的主要问题。提出了掺加钢纤维的自融雪沥青混合料的设计方法,通过室内试验研究了不同钢纤维掺量下沥青混合料试件的级配层间剪切强度、剪切位移、电导率。

Combined with the research status at home and abroad,the ultra-thin salted self snowmelt asphalt overlay material is applied to the pavement engineering of highgrade highway.The main problems existing in the existing ultra-thin salted self snowmelt asphalt overlay materials are obtained,and the design method of self snowmelt asphalt mixture mixed with steel fiber is put forward.Through indoor mechanical test,the graded interlayer shear strength and shear displacement of Asphalt Mixture Specimens with different steel fiber content are studied.
