Abstract: The Buton rock modified asphalt has the similar high temperature performance with the SBS modified asphalt, but the price is much less than the SBS asphalt. Moreover, it can be highly integrated with asphalt without polymerization, and has been considered as a green road construction materials. Wet processing technique has been chosen to produce the Buton rock modified asphalt, compare with the traditional dry processing technique, natural rock modified asphalt is much more easier to fuse with asphalt, and the performance of the mixture could be much stable. With the application of the wet processing Buton rock modified asphalt in Anhui Province, China, the mix design method and road performance has been tested and researched, and the tests results could meet the requirements of the national specification.

Key words: Buton rock modified asphalt, wet processing technique, asphalt mixture, mix design, road performance test.
