Abstract
The present invention relates to a novel aromatic polysulfide and an asphalt composition containing the same, and more particularly, to a novel aromatic polysufide having repeating units of the following formula (I), an asphalt composition, an asphalt paving composition, an adhesion promoter and an UV absorber containing the same: The asphalt paving composition of this invention exhibits excellent adhesiveness to aggregate component and better water resistance, and renders the temperature susceptibility less sensitive, thereby greatly improving durability.
