Abstract
The effects of the period of thermal degradation of polymer modified asphalt (MA), and the content of asphaltene constituent in MA were discussed. By mixing the straight asphalt and styrene-butadiene-styrene triblock copolymer (SBS) at 190 degrees C for 6h. MA was produced. After that MA was thermally degradated at 190 degrees C for 5 -12 days. During the thermal degradation of MA, the yield of polar constituent (asphaltene) increased gradually with the decomposition of SBS. However, the decomposition of SBS was inhibited by MA of high asphaltene content.
