Abstract
We introduce a novel method that could modify neat asphalt. A polymer-forming monomer, dimethylphenol( DMP) was added to the neat asphalt and polymerization was occurred autonomously, without adding any external catalyst for the polymerization, only with oxygen molecules in the air. The polymer produced in the asphalt was polyphenyleneoxide( PPO) and it enhanced the mechanical properties of the asphalt. Compared with the neat asphalt, the tenacity and toughness of the DMP-modified asphalt were two and half times and three times high, respectively.
