阳离子乳化沥青是近十几年来在国内外新发展起来的筑路材料.大庆油田公路工程公司自1980年开始进行阳离子乳化沥青路用性能的研究,先后突破了乳化剂、乳化机、乳化工艺、铺筑公路及路养护等一系列技术难关.研制出供试验用的齿轮泵加喷嘴乳化机,生产用的齿轮泵加喷嘴循环乳化机,齿轮泵柱塞喷嘴一次乳化机,并建成大型阳离子乳化沥青生产线.铺筑了贯入式路面660m~2,拌合式路面347m~2及6cm碎石稳定路3500m~2.通过三种试验路面证明,阳离子乳化沥青具有良好的工作度,路面各项技术指标均能达到国家标准.阳离子乳化沥青与热沥青施工相比,可节省热能30～50%,节省沥青15～40%,扩大骨料来源(酸性、碱性均可用),减少环境污染,减轻劳动强度,节省劳力20%;在东北寒冷地区一年内可延长施工期一个月.
Cationic emulsified asphalt is a newly developed road building material both at home and abroad in recent ten years.Daqing Oilfield Highway Engineering Company has been researching the road performance of cationic emulsified asphalt since 1980 and successively broke through emulsifier, emulsifying machine, emulsification process, Paving road and road maintenance and a series of technical difficulties developed for the test gear pump plus nozzle emulsification machine, the production of gear pump plus nozzle cycle emulsifier, gear pump plunger nozzle emulsification machine, and the completion of large-scale cationic emulsification Asphalt production line paved the penetration of the road 660m ~ 2, mixing road 347m ~ 2 and 6cm gravel stabilized road 3500m ~ 2. Through the three test pavement proved that cationic emulsified asphalt has good workability, the road surface technology Indicators can reach the national standard.Cationic emulsified asphalt compared with hot asphalt construction, can save 30-50% of heat, save asphalt 15-40%, expand the source of aggregate (acidic, alkaline are available), reduce environmental pollution, reduce Labor intensity, labor-saving 20%; in the northeastern cold areas can be extended within one year of construction period of one month.
