| Abstract: | According to the amount and polarity of solvents , the asphalt was directly divided into different components . The distributions of them were investigated in details. Meanwhile, the molecu-lar weight of each component was measured by VPO method, and the distributing rule of molecular weight was also studied. The studies on the distributing rule of component and molecular weight had great significance on comprehending the adhesive properties of asphalt deeply. |
