前言路面材料回弹模量值,是理论法中的一个重要的设计参数. 多数国家的理论法中,路面材料采用动弹性模量.如美国地沥青协会设计法,美国陆军水道试验站,壳牌(Shell)石油公司设计手册,加拿大等国均采用动弹性模量. 苏联在应用理论法时,路面材料弹性模量是利用承载板法获得,属静弹性模量. 我国自60年代开始至今,路面材料回弹模量的现场测试方法,采用了整层试槽法,或分层测定反算法.相似于苏联的静弹性模量.
In the theory of law in most countries, the pavement materials use dynamic elastic modulus, such as the American Asphalt Association design method, the US Army Waterway Test Station, Shell (Shell) oil companies design manuals, Canada and other countries are used in the dynamic modulus of elasticity.The Soviet Union in the application of theoretical method, the elastic modulus of pavement material is obtained using the bearing plate method, is a static elastic modulus.China since the 1960s so far, The field test method for the modulus of resilience of pavement materials uses a full-thickness test cell method or a stratified inverse method, similar to the static elastic modulus of the Soviet Union.
