A new process based on reaction between asphalt and block copolymer of styrene and butadiene for manufacturing polymer modified asphalt for pavement is presented. Among the reactions between polymers and asphalt there are vulcanization (crosslinking reaction), reaction of functional groups on copolymer or grafting polymer with special groups on asphaltene and acidification, these reactions have been used for modifiction of asphalt. Good comprehensive performance of the polymer modified asphalt for paving was achieved by the reaction modification. A plant for manufacturing the polymer modified asphalt based on the new technology will be completed in a few monthes in China.
