Setting of Function Layer of Cement Concrete Pavement

摘要

The paper seeks to analyze the necessity of setting functional layer between base and surface course of cement concrete pavement. Based on laboratory test, test device is developed to test accumulated deformation of the functional layer mixture. Use common mixture AC-16, AC-13, and AC-10 to analyze the increasing law of cumulative deformation of mixture. According to the results, 3.5mm is set as the maximum limits of accumulated deformation for function layer under specified test condition in this article, which provides theoretical reference for the pavement layer design of cement concretes.
