本文介绍了3组SBS改性沥青样品的烘样试验。一是同配方同数值指标同量的SBS改性沥青生产样品在不同烘样方式下烘至流动性良好状态时进行制模试验,比较性能指标的检测结果是否存在差异;二是同配方同粘度不同量的SBS改性沥青生产样品在同温度下进行烘至流动性良好状态所需时间的试验:三是不同粘度同量的几种SBS改性沥青样品在同温度下进行烘至流动性良好状态所需时间的试验。结果表明烘样的温度根据样品的粘度情况进行设置比较符合实际。只要在样品烘至流动性良好的状态时进行制模试验,烘样方式的不同对SBS改性沥青性能指标的检测结果影响不大。
This article describes the three sets of SBS modified asphalt sample bake test. First, with the same formula with numerical indicators SBS modified asphalt production samples baked in different baking mode to good fluidity when the molding test, the comparison of performance test results there is a difference; the same formula with the same viscosity Different amounts of SBS modified asphalt samples produced at the same temperature to bake the fluidity of good state test: Third, different viscosity and the same amount of several SBS modified asphalt samples were baked at the same temperature to good fluidity The state of the test time required. The results show that the temperature of the sample is set according to the viscosity of the sample more realistic. As long as the sample bake to good fluidity of the state when the molding test, the different ways of baking sample SBS modified asphalt performance test results have little effect.
