An Investigation of the Structural Properties of Stabilized Layers in Flexible Pavement Systems.

摘要

In recent years mechanistic models have been advocated as a tool for predicting the performance of pavement systems under aircraft traffic. In the investigation reported herein,layered elastic and nonlinear finite element models were used to determine the benefit of stabilized layers within a pavement system. The performance of several types of pavement structures that were constructed and trafficked under controlled conditions at the US Army Engineer Waterways Experiment Station were analyzed with respect to predicted response,measured response,and manifestation of traffic distress in the pavement systems. From the analysis,relationships were developed between pavement life and predicted response such that the benefit of the use of stabilized materials within a pavement system could be examined based on the influence which the material would have on the predicted life of the pavement system.
