In order to compare and analyze Superpave and Marshall design method for asphalt mixture. Through the analysis about gradation selection, predicition asphalt content, the determination method of theoretical maximum density, the compaction methods of specimens, the determination method of optimum asphalt content and the test method of mixture performance of these two design methods. The following conclusions have been come to: Superpave design method is better than Marshall design method for asphalt mixture.
Key words: Superpave / Marshall design method / gradatiom / compaction methods / optimum asphalt
