The effct of adding method of aluminum powder on the expansion rate and air content was also studied. The results indicate that the expansion rate and air content were greatly influenced by the adding method. Cement asphalt mortar prepared with the adding method of low mixing for 1min before adding aluminum powder and then slow mixing for 30min has proper expansion rate and stable air content.
