| 摘 要： | 选用工程中常用的几种纤维,结合工程应用要求,试验分析了纤维的吸湿性、耐热性,并通过网篮析漏试验、动态剪切试验和沉锥试验,讨论了纤维对沥青的稳定和吸附作用,以及纤维对沥青混合料“加筋”效果和作用机理。研究表明有的纤维“吸附、稳定”性能好,而有的纤维“加筋、桥接”效果好,在应用纤维时,应根据纤维的主要特点以及沥青混合料的使用要求来选用。

| Abstract: | In order to study the application effect of fiber in asphalt mixture,several fibers often used in project were chosen,their moisture absorption and heat-endurance were analyzed in accor- dance with application requirement of a project.Further,web leaking test,DSR and wimble penetra- tion test were carried out on fiber asphalt mortar,based on the tests,the function of fibers in asphalt are discussed and concluded:absorption,stabilization,bridge and steeling,and test results indicate that different fibers have different advantage.The fibers should be used in accordance with its merit and asphalt mixture requirement. |
