高模量外加剂与抗车辙剂的异同点研究

Research on Similarities and Differences between High Modulus Admixture and Anti-rut Agent

目前市场上提高沥青路面抗车辙性能的产品主要有抗车辙剂和高模量外加剂两类产品。这两类产品外观较为相似,产品种类较多,使用过程中界限模糊。结合外加剂生产及路面养护工程中的多年使用经验,从生产原理、路用性能指标及实际应用三个方面详细阐述了两类材料的差异性及各自的优缺点,为公路建设中两种材料的选择应用提供了理论与实践参考。

At present,there are mainly two kinds of products that can improve the rutting resistance of asphalt pavement in the market,i.e.anti-rut agent and high modulus admixture.The appearance of these two kinds of products is similar,the product category is rich,and the boundary is fuzzy in the use process.Combined with many years'experience in admixture production and pavement maintenance engineering,the differences and advantages and disadvantages of the two kinds of materials are elaborated from three aspects of production principle,pavement performance index and practical application,which can provide theoretical and practical reference for the selection and application of the two materials in highway construction.
