Preparation and performance test phosphorus slag powder base tunnel asphalt pavement retardants
摘要
Abstract
Six kinds of phosphorus slag powder-based flame retardants were prepared in or-der to solve fire-proof safety problem of tunnel asphalt pavement A-F.The combustion prop-erties of flame retardants were evaluated by DSC experiment and the optimal flame retard-ants were selected.The pavement performance and limiting oxygen index of flame-retardant modified asphalt with different amounts of retardants were tested,then the optimum a-mount of flame retardants and flame retardancy were analyzed.The Cone thermal test was conducted to study the flame retardant properties of flame retardant asphalt mixture.the re-sults show that flame D,F two endothermic peaks are obvious.With the addition of flame retardant D and F,the oxygen index of asphalt was significantly improved.Different dosage of the addition of flame retardant D,F can meet the requirements of the pavement perform-ance.The optimum amount of flame retardant is 8%.Compared with the nonflame-retardant asphalt mixture,the retardancy of flame-retardant modified asphalt mixture is better:its ig-nition time is longer,heat release rate is slower and the total heat release is lower.the flame retardancy of asphalt and asphalt mixture mixed with flame retardant D,F were obvious and flame retardant D has the best flame retardancy.关键词
