Abstract: | The effects of aromatic oil on the swelling degree of the modifier in bitumen were analyzed from macro and micro perspectives. The evaluation indicator of swelling degree was put forward and the prediction model of swelling degree was established. The result shows that the swelling degree of direct-to-plant SBS modifier in bitumen can be evaluated by the structure fineness of SBS after swelling. There is an optimal content of aromatic oil makes the direct-to-plant SBS has the best swelling degree. The swelling degree determines the performances of the direct-to-plant SBS modified bitumen to a certain extent. |
