摘　　要：对公路建养中常用的温拌技术和目前出现的温拌新技术进行了梳理和总结。常用的温拌技术包括有机降黏剂、表面活性剂和发泡技术,这类传统温拌技术降温效果有限。复合温拌技术是将表面活性剂与发泡技术相结合的方式,可以进一步降低沥青的黏度和施工温度。复合温拌剂通过功能组分引入,可以解决传统温拌剂在沥青性能改善上的不足或者满足特殊功能需要。新型温拌剂的研制已在业界逐步展开,而且部分研究工作已进入试验应用阶段。In this paper,the warm mixing technology commonly used in highway construction and main-tenance and the new warm mixing technology were reviewed and summarized.Common warm mixing tech-niques include organic viscosity reducers,surfactant and foaming techniques which have limited cooling effect.The combination of surfactant and foaming technology can further reduce the viscosity and construction temper-ature of asphalt.The modification technology of warm mixing agent can solve the shortcomings of traditional warm mixing agent in improving asphalt performance.The new warm mixing agents have been studied by some researchers.However,the new agents remain in the experimental stage and has not been widely used.
