| 中文摘要: |
| 以基质沥青混合料与80目10%橡胶粉沥青混合料为试验对象，分析橡胶粉沥青混合料在温度和氯盐侵蚀耦合作用下对马歇尔试验结果的影响。试验考虑了NaCl溶液浓度和浸泡时间2个因素，进行了18组试验。结果表明:基质沥青混合料和橡胶粉沥青混合料在NaCl溶液中，随着浸泡时间的延长，稳定度呈现下降趋势；橡胶粉具有改善沥青混合料抵抗温度、盐侵蚀的能力。SEM微观分析表明:NaCl溶液的盐腐蚀加剧了沥青混合料的进一步损伤。 |

| This experiment analyzes the relation between rubber power asphalt mixture and Marshall Test results under the action of the temperature and salt corrosion, by using matrix asphalt mixture and 80 mesh 10% rubber power. It carries out 18 tests, considering two factors of NaCl solution solubility and soak time. The tests results indicate that the stability of the matrix asphalt mixture and the rubber power asphalt mixture that immersion in the Nacl solution is trending downward, with the increase of immersion time; Rubber power can improve the ability of asphalt mixture for resistance temperature and salinity. According to SEM micro-analysis, NaCl solution of salt corrosion can contribute to the further damage of asphalt mixture. |
