文档介绍：SBRS：性沥青的拓展与应用
摘要
本文对SBR改性沥青的性能及沥青中加盐后的表面润湿角、渗盐情况进行了研 究， 这些问题的研究不但能改善路面沥青材料性能的作用， 还以更好的防止冬天路面 结冰的现象。
通过试验，测定了 70#国产沥青在不同掺量SBRBW生下基本技术指标的变化情况， 以此研究改性沥青的路用性能和 SBR勺最佳掺量。并且测定了沥青中加入不同无机盐 和表面活性剂后润湿角变化及渗盐情况； 并将改性后的各种沥青涂在不同氯化钠浓度 的水泥上，然后再测润湿角及渗盐情况。试验结果表明基质沥青经SB儆性后低温性 能和延度得到大幅度改善，高温性能也得到一定改善；综合各方面的因素， SBR改性
剂的最佳掺量确定为 3%。沥青中加入盐后润湿角会变小，不利于防结冰，但由于渗
盐后会降低水的凝固点。
总体来说改性后的沥青在防止道路结冰有一定的应用价值。

ABSTRACT
The performance of the SBR modified asphalt and asphalt surfaces in contact angle after the salt, salt permeability are study of these problems can not only improve the effect of material properties of asphalt pavement, but also can better prevent winter road junction ice phenomenon.
Through laboratory tests, the basic technical indicators of 70 domestic SBR modified asphalt is measured at different dosage changes , as a means of modified asphalt pavement performance and the best content of SBR. And we measuredwetting angle change and infiltration salt conditions after add different inorganic salts and surfactants, The results showed that after SBR modified asphalt low temperature performance and a significant improvement in ductility, high temperature performance has also been improved to some extent, but the effect is not very obvious;integrated various factors, SBR modifiers identified as the optimal dosage 3%. Adding salt pitch make the wetting anglebecomes smaller, which is not conducive to anti-icing, but due to salt penetration, it will reduce the freezing point of water.
Overall, promotion and application of modified asphalt is still of great value.
