| Abstract: | Based on the flame-retardant mechanism of modified asphalt and requests and development trend of flame retardants,the paper chose IFR to make flame-retardant asphalt.Indicators as limiting oxygen index,synergistic efficiency and flame retardant value were employed to evaluate the flame retardant effectiveness of SBS modified asphalt.After analyzing the flammability of a dollar flame-retardant,binary formulation,ternary formulation system,the optimum composite ratio was determined. |
