以JTJ 052-2000《公路工程沥青及沥青混合料试验规程》中T0661的方法为试验依据,对改性沥青离析试验中条件因素进行了探讨。结果表明:对某些成品改性沥青,离析过程中的冰箱冷却温度与试验条件对离析指标具有明显的影响;分析认为这种影响与改性沥青的改性工艺、改性剂掺量及基质沥青有关,相容性好的样品离析受试验条件影响小,而相容性不好的样品离析受其影响大。
Based on the test method of T0661 of JTJ 052-2000 “Road engineering asphalt and bituminous mixture test code”, the condition factors in the segregation test of modified asphalt were discussed. The results show that for some finished modified asphalt, the cooling temperature and the experimental conditions of the refrigerator during the separation have a significant effect on the separation index. The analysis shows that the influence of modification temperature, modification amount of the modified asphalt, Asphalt-related, well-compatible sample segregation is less affected by the test conditions and samples with less compatible segregation are greatly affected by it.
