Abstract: Preparation process of asphalt directly influences its performance.Key parameters of clear binder were analyzed,such as composition proportion,swelling process,shearing process,development process and so on.Conventional performance indexes,phase transition performance and mechanical performance of clear binder were also compared with road petroleum asphalt under the optimum technological conditions.Reaults show that 50％ of resin and 50％ of solvent oil are mixed into prepare clear binder,and then 6％ of modifier are also mixed into the blends under the optimum conditions.It has a better pavement performance and a similar phase transition process compared with A90 road petroleum asphalt.Mechanical properties of the bright colored asphalt are improved by added modifier,especially low temperature toughness and flexibility.
