This product is also available as a blending component of petroleum asphalt and SBS modified bitumen cosolvent. Since most Chinese bituminous oil component is missing - saturated hydrocarbons, aromatic hydrocarbons, resulting in them as raw materials to produce asphalt main quality indicators difficult to achieve product standards. As a high aromatic content of aromatic oil to meet to reconcile the requirements of the asphalt. Colored asphalt special aromatic oils have high temperature, low temperature resistance, and good compatibility with asphalt, bitumen compared to the original, high temperature performance, stretch, stretching, flexibility, compatibility with the mixture, anti-aging properties, etc. terms, with significant improvements and enhancements. (1) better compatibility with SBS (2) temperature resistance (3) low volatile and difficult to extract (4) high aromatic content (5) PCA content is low (6) adjusting the viscosity of bitumen, tackifying
