摘要
改性乳化沥青微表处技术在我国已经得到大量的应用,该技术相对于传统的乳化沥青稀浆封层技术具有标准高、成本低等特点.以宁夏境内国道110线路段为例,采用特殊的生产工艺,在改性乳化沥青中掺配矿料、水泥、水等制备出具有一定和易性和稠度的稀浆混合料;再使用专用机械设备,按要求厚度将其均匀摊铺到旧路面上,这种微表处技术,有效地处治了原路面车辙和裂缝等病害,使旧路面的抗滑、抗磨擦性能明显提高.
Technoogy microlayer of modification emulsified asphalt have been widely applied in China. This technique has features of high level, low costs and etc. comparing with the traditional technic thin paste seal of emulsified asphalt. Taking example of national highway 110 line within Ningxia＇s borders, this study adopting special production craftwork, mixing inert solid, cement, water etc. into modification emulsified asphalt, creating a thin paste mixture that have some kind of workability are consistency. Further more, it spread well-distributed to old road surface according to the demand thickness using special mechanical equipment. By using this microlayer technic, the disease on the old road surface such as track, crack and etc. are cured effectively, the function of antiskid and anti-friction are increased obviously.
