Modified asphalt was prepared by using laboratory high shear emulsification mechanism under different content of organic bentonite. Performance of modified asphalt of the different content of organic bentonite was analyzed through the detection of modified asphalt performance. And at the same time with different content of scrap rubber on the asphalt content of 5% bentonite was modified. Composite effect modified by the organic bentonite and waste rubber powder asphalt was demonstrates. The reasons for its composite modified was briefly described.
