摘　　要：随着对高速公路中桥头跳车现象的重视,微表处技术以其特有的优越性在路面工程中得到广泛的应用。基于工程实践和试验现象与数据分析微表处技术的使用性能。结果表明：微表处混合料沥青乳液乳化剂采用1.2%-1.6%,基质沥青∶乳化剂∶改性剂∶稳定剂=51∶1.3∶4∶0.2为最佳配合比,7%为室内的最佳含水量;微表处混凝料油石比为6.0%-7.0%较为合适,建议高速公路桥头采用6.5%的油石比;微表处技术较好的提高高速公路路面的抗滑性能和平整度,并有很好的耐久性。本文的结果能为微表处技术处理高速公路桥头顺坡实体工程应用研究用提供参考。With emphasis on highway bridge head jumping phenomenon,micro-surfacing technology with its unique superiority in pavement engineering are widely used. Based on engineering practice and experimental phenomena and data analysis,the performance of micro-surfacing technology is analyzed. The results show that the micro surfacing mixture asphalt emulsion emulsifier by 1. 2% to 1. 6%,asphalt emulsifier： modifier： stabilizer = 51 ∶ 1. 3 ∶ 4 ∶ 0. 2 for best fit than. 7% for indoor optimum moisture content; micro table place mixed coagulation aggregate than 6. 0% - 7. 0% is more appropriate,and suggested the highway bridge by 6. 5% asphalt aggregate ratio; micro surfacing technology better improvement of Expressway Pavement anti slide performance and smoothness,and good durability. The results of this paper can provide reference for the application of the micro surfacing technology in the engineering application of the highway bridge.
