高抗滑性微表处混合料的制备及性能研究
Study on preparation and performance of micro-surfacing mixture with high skid resistance
摘要
Abstract
[Purposes]This study aims to obtain modified emulsified asphalt micro-surfacing mixture with excellent skid resistance.[Methods]Through orthogonal experiment,the influence of aggregate gradation,modified emulsified asphalt,water and other factors on the performance of micro-surfacing mixture was explored.The influence of aggregate gradation on the skid resistance decay law of micro-surfacing mixture was further analyzed by simulating the rubbing effect of driving on pavement at road intersection with asphalt emulsion wet wheel abrasion tester.[Findings]Modified emulsified asphalt,water and gradation all had different effects on the performance of the mixture.When the content of modified emulsified asphalt and water was 14%and 10%,and the mineral aggregate gradation was 2,the micro-surfacing mixture was the optimal ratio.[Conclusions]The emulsified asphalt mixture modified by styrenic block copolymers(SBS)has excellent skid resistance and can be widely used in the maintenance of asphalt pavement.关键词
