利用FWD(落锤式弯沉仪 ) ,建立一种快速方便地评定路面各层的弹性模量方法 ,并与弹性层状体系理论方法进行比较。该方法简单实用 ,并且误差在容许范围内。
Using FWD (drop weight deflection instrument), a method for quickly and conveniently evaluating the elastic modulus of pavement layers was established and compared with the theoretical method of elastic layered system. The method is simple and practical, and the error is within the allowable range.
