Abstract: In this paper, in order to promote the development of flame-retardant modified asphalt technology, the flame-retardant mechanism was further explored through the analysis of the change of components in the combustion reaction process of asphalt. Through the selection of raw materials and preparation process of flame-retardant modified asphalt at home and abroad, the influence of flame-retardant content and preparation process on the flame-retardant effect was explored. The basic performance evaluation methods of flame-retardant modified asphalt at home and abroad are investigated from the macroscopic point of view. Based on the difference of various flame-retardant materials, the flame-retardant properties of asphalt modified by organic flame retardant, inorganic flame retardant and composite flame retardant were compared and evaluated. Finally, the flame-retardant mechanism of flame-retardant modified asphalt is discussed from the microscopic point of view.
