A sprayed colored asphalt was prepared with base oil,styrene-butadiene-styrene(SBS),and petroleum resin C9 as raw materials,ethyl ac-etate and solvent oil as composite solvents,and its performance was evaluated.The results showed that when the mass fraction of SBS was 9％and the mass fraction of petroleum resin was 45％,the prepared colored asphalt could meet the requirements of GB/T 32984-2016.When the mass ratio of ethyl ac-etate to solvent oil was 1∶9,the concentration of col-ored asphalt solution was 50％,and the mass frac-tion of dolomite powder was 50％,the viscosity of the prepared sprayed colored asphalt was less than 1.0 Pa·s,and the surface drying time was shorter than 60 min.The sprayed colored asphalt had good adhesion,abrasive resistance,impermeability,and low temperature flexibility,which could achieve the effect of easy spraying and short-term open traffic.
