摘　要: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。[著者文摘]

MAnalysis of the Properties of Liaohe Asphalt Number 90 Modified by the Styrene Butadiene Rubber（SBR）WANG Lei , ZHANG Min - jiang , LIU Feng, YU Bao - yang1 ,School of Civil Engineering,Shenyang Architecture University,Shenyang,Liaoning 110168 ;2 ,Dept. of Resource and Architecture ,Liaoning Institute of Science and Technology, Benxi, Liaoning , 117022, China Abstract: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.[著者文摘]
