粘层油与钢界面的粘结性能易受到灰尘与温度等因素的影响,从而出现层间污染,导致路面损坏。自行设计了砖面粘结强度拉拔试验方法,探讨了热沥青、乳化沥青、环氧沥青、稀释沥青4种粘层油与钢界面粘结性能的影响因素,得出了不同沥青对界面灰尘的耐受能力。同时从养护时间、施工温度等方面对不同的粘层油提出了施工建议。
Abstract:The bonding quality of interlayer bonding material and steel interface is easily affected by temperature and ash, which may cause interlayer pollution and damage pavement. In this paper, an experimental study testing the drawing behavior of brick surface bonding strength was designed to investigate the factors that influence the bonding strength of 4 kinds of asphalt and steel interface,and concluded each kind of asphalt's tolerant ability to ash. Furthermore, some construction proposals were given concerning maintenance time and construction tem- perature.
