Abstract
This paper presents a summary of a study to investigate the feasibility of predicting fatigue cracking and rutting in full depth asphalt pavements by centrifuge modeling. This is accomplished by constructing a small-scale centrifuge model and measuring directly the resilient tensile strains at the bottom of asphalt layer and the accumulated permanent on the pavement surface under repeated loads. The purpose of using a centrifuge is to insure that the stresses and strains due to self-weight are the same in the small-scale model as in the prototype pavement. Model pavements in two different scales of 1:10 and 1:20 were constructed, using two different asphalt contents and compaction levels. It was found that the resilient deformations and strains measured in the 1:10 models checked well with those in the 1:20 models for all test combinations. Although the permanent deformations experienced a large range of variations, the average of the 1:10 models also checked reasonably with that of the 1:20 models.
