An Approach to Enhance the Local of Calibration of Concrete Pavement Performance

This paper discusses an approach to enhance the accuracy and selection of fatigue damage calibration coefficients by addressing more directly the effect of the set gradient on performance. The approach was originally introduced over 20 years ago in a paper by Zollinger and McCullough when calibration and mechanistic-empirical (ME) methodologies were becoming a topic of interest. A method to extract the set gradient from performance data through analysis is outlined and presented in detail. The correlation of the set gradient to key performance parameters is also discussed along with the factors that influence the magnitude of the set gradient that forms in a concrete pavement soon after construction.
