A little emulsoid was added in the bitulith to improve the performance of asphalt pavement . the new material is of rigidity and flexibility . we called it semi - rigid bituminous emulsion 乳化渣油半刚性路面材料就是针对沥青混凝土的弱点进行改性研究的一种新型复合材料，其在增加材料刚度的同时仍保留了部分粘弹性特征。

The results showed that the acr emulsoid particle size and its distribution can be adjusted by varying the amount of seed emulsion used in the pre - emulsionized seed - emulsion polymerization , and the acr emulsoid particles have core - shell structure obviously 结果表明，采用预乳化种子乳液聚合法制备acr乳液，可以有效地控制乳胶粒径及分布；且所合成的acr乳胶粒子具有明显的核壳结构。

The emulsoid particle size and its distribution were determined by laser particle sizer . the composition changes of acr were inspected by ir , and the core - shell structure was observed by tem . the morphologyes of acr resin particles were inspected by polarization microscope at last 通过激光粒度分析仪对所合成的乳胶粒径及其分布进行了分析测试，借助于ir考察了所合成的acr的组成变化，并通过透射电镜对所合成的acr的核壳结构进行了验证，最后借助于偏光显微镜观察了破乳干燥后得到的acr粒子。

Permeable durability reinforcing agent used for concrete surface is a material sealing surface of concrete , and it can permeate into inner of concrete and fill or block the pores of concrete surface with dry crystal or emulsoid generated by reaction between it and chemical compound in concrete 混凝土表面用渗透型耐久性增强剂是一种针对混凝土表面的渗透封闭型材料,其可渗入混凝土内部,并通过干燥结晶或与混凝土内部相关物质反应生成乳胶体将混凝土表层的孔隙填充、堵塞,对已有混凝土结构的防护具有重要意义。
