| 摘 要： | 通过承载板试验现场测定路面当量回弹模量,与弯沉检测数据进行回归分析,建立沥青路面计算弯沉与路面当量回弹模量的经验公式,并与现行规范中不同的换算公式进行比较,得出路面当量回弹模量适合的确定方式,可为公路改扩建工程中沥青路面加铺设计提供参考依据.

| Abstract: | By testing equivalent rebound modulus of asphalt pavement with bearing plate in site, and re- gression analysis on the test result and deflection test data, this paper established the empirical formula between deflection and equivalent rebound modulus of pavement, and compared it with formulae in speci- fications. The suitable determination method for equivalent rebound modulus of pavement was put forward to provide reference for the pavement design of highway reconstruction. |
