KSH温拌改性沥青胶结料性能试验研究

通过SBS改性沥青掺配KSH温拌剂前后对比试验分析，从三大指标、DSR和BBR试验入手分析两种沥青的综合性能。试验结果表明:掺配KSH温拌剂后并未有效改善SBS沥青的综合性能，尤其是抗老化性能和抗低温开裂性能还有所降低，对于高温性能的改善，仅从RTFOT前后的试验数据来看，未能得出一致的结论，还需进一步的试验验证。

Test Study on Performance of KSH Warm-mix Modified Asphalt Cementing Material

Through comparision between the tests on SBS modified asphalt doped with KSH warm mix agent or not,the comprehensive properties of these two kinds of asphalt are analyzed on the basis of three indexes,DSR and BBR tests.The result shows that the comprehensive properties of SBS asphalt doped with KSH warm mix agent is not improved greatly,even aging and low-temperature cracking resistance performance is inferior.In respect of the improvement on high-temperature performance,the agreed conclusion does not reached only depending on the test data before and after RTFOT and further verification is required.
