聚合物改性乳化沥青集改性沥青和乳化沥青的优点于一体,可应用于沥青路面的稀浆封层和微表处等方面。介绍了3种聚合物改性乳化沥青的制备工艺,指出应根据自身设备情况选用合适的制备工艺。现行的指标不一定适合于聚合物改性乳化沥青,应加强聚合物改性乳化沥青性能评价指标的研究,粒径和形貌对其性能影响较大。多应力蠕变恢复实验(MSCR)是近年来提出的动态剪切流变方法,该方法测出的不可恢复蠕变柔量(Jnr)和恢复率(R)可以更好评价聚合物改性乳化沥青的高温性能。共聚焦激光扫描显微镜(CLSM)可用来研究改性乳化沥青中聚合物分布、网络形成、相容性等。反应性聚合物改性沥青和纳米复合材料改性沥青是未来的发展方向,以解决现行的聚合物改性沥青的缺点。功能化改性剂和新型改性剂,在乳化剂中导入功能性官能团如胺、酰胺、咪唑啉等是未来的发展方向。
Polymer modified bitumen emulsion has the advantages of modified bitumen and asphalt emulsion,and has been universally applied to slurry seal and micro-surfacing for asphalt pavement.There are several ways to prepare modified bitumen emulsion and the factory should select proper processes according to equipment.The performance of modified bitumen emulsion are not easy to demonstrate with the conventional methods,so different evaluation methods are needed.Particle size distribution and morphology have a great effect on its performance.Multiple Stress Creep and Recovery testing(MSCR) was a newly developed dynamic shear rheological method.Non-recoverable compliance(Jnr) and Recovery(R) testing result obtained from MSCR provides good technical information of high-temperature behavior for Modified bitumen emulsion.Confocal laser scanning microscopy(CLSM) has been used to assess the polymer distribution,network formation and compatibility for polymer-modified bitumen emulsions.In order to remove the drawbacks of modified bitumen emulsion,reactive polymer modified asphalt and nanotechnology are the development trend.Functionalized and new modifier and functionalized groups in emulsifiers such as amines,amides,imidazoline,etc,these are future development direction.
