Analysis of Temperature Sensitivity of the Synchronous Pavement Sealing

Through the pull-out tests of the following three pavement sealing techniques: rubber asphalt, SBS modified asphalt and SBR modified emulsified asphalt, a contrast was made to analyze the influence of temperature on the pull-out strength and the displacement value of damaged sealing coats, so as to analyze the temperature sensitivity of the three sealing coats of synchronous pavements. The results show that: the rubber asphalt sealing coat, modified by the rubber power, has good temperature sensitivity and the temperature susceptibility of asphalt has been improved, with a greater ductility in low temperature and a better resistance to flow deformation in high temperature.
