SBR丁苯橡胶对辽河90#基质沥青改性的分析

Analysis of the Properties of Liaohe Asphalt Number 90 Modified by the Styrene Butadiene Rubber(SBR)

为了分析基质沥青经SBR改性后的性能,通过实验测定不同掺量SBR改性基质沥青后的三大指标,并进行分析。实验结果表明基质沥青经SBR改性后低温性能得到大幅度改善,高温性能也得到一定改善,但效果不是很明显,加入稳定剂可以更好的改善改性沥青的低温性能。

In order to analyze the performance of asphalt modified by SBR , three major indexes after mixing it with different percentage of SBR and measured. The results show that the asphalt modified by SBR has significant improvement in its low - temperature property, which has much better improvement than its high - temperature property. The low - temperature property of the modified asphalt could be further improved by adding some stabilizer to it.
