| Abstract: | Combining with Ninggao expressway reconstruction project, high modulus asphalt cement is prepared with low grade asphalt particles and 70 # road asphalt, mix ratio is designed using French EME method. On the basis of the mix ratio design, the construction technologies are summarized through testing road paving. Research shows that high temperature performance of high modulus asphalt mixture can meet the design requirements and reduce pavement rutting disease effectively. |
