By using asphalt wheel rolling machine， the aggregate heating temperature and the mixture formation lower limit temperature of the Evotherm warm mix asphalt mixture were studied on the equal volume parameter principle. It was found that the water stability and fatigue performance of it are better than that of the hot mix asphalt mixture designed by Marshall wheel rolling method. Other indexes are equivalent to that of hot mix asphalt mixture. The results show that for the same material composition and method of formation， by the design methods of hot mix asphalt mixture asphalt aggregate ratio and the Marshall wheel rolling machine， the temperature of warm mix asphalt mixture heating and mixing material forming can be determined more accurately and the temperature environmental protection of it will be more effective.
