由于材料的复杂性质，改善阻燃剂和沥青之间的相容性是一项艰巨的任务。探索一种低掺量的复合阻燃剂，以改善阻燃剂与沥青的相容性。以氢氧化镁、聚磷酸铵、三聚氰胺为因素设计正交试验。通过吸油率和活化指数的测试，确定钛酸酯对阻燃添加剂的影响。通过路用性能试验对阻燃剂的阻燃效果进行了评价。通过氧指数试验确定了阻燃剂对沥青结合料燃烧性能的影响。研究结果表明，新型复合阻燃剂在改善阻燃剂与沥青的相容性、降低沥青结合料极限氧指数方面效果更好。
Improving the compatibility between flame retardant and asphalt is a difficult task due to the complex nature of the materials. This study explores a low dosage compound flame retardant and seeks to improve the compatibility between flame retardants and asphalt. An orthogonal experiment was designed taking magnesium hydroxide, ammonium polyphosphate, and melamine as factors. The oil absorption and activation index were tested to determine the effect of titanate on the flame retardant additive. The pavement performance test was conducted to evaluate the effect of the flame retardant additive. Oxygen index test was conducted to confirm the effect of flame retardant on flame ability of asphalt binder. The results of this study showed that the new composite flame retardant is more effective in improving the compatibility between flame retardant and asphalt and reducing the limiting oxygen index of asphalt binder tested in this study.
