Study on the High-Temperature Warning of Asphalt Pavement

According to the results of dynamic stability and the softening point of bituminous test, the most adverse temperature which would produce high-temperature rutting of asphalt pavement were obtained. At the same time through the acquisition temperature data of asphalt pavement in summer, using statistical analysis software SPSS, the relationship were deduced between air temperature and the temperature under the road surface 4cm. Compared this relationship with the measured temperature, the result shows they have a good correlation.
