California Efforts Towards Mechanistic-Empirical Pavement Design
Caltrans has been actively preparing to take advantage of the potential implementation of the mechanistic-empirical approach to the design of highway pavements. This paper presents the progress made to date regarding development and evaluation of software applications and models, and presents the currently ongoing efforts for field calibration. The new packages that have been developed for the analysis of flexible and rigid jointed pavement, which are called respectively CalME and RadiCAL, are described. The paper presents results of a sensitivity study that has been performed on the NCHRP l-37a software. The sensitivity evaluation has already been conducted for new rigid jointed, and it is currently in development for continuously reinforced pavements and new flexible pavements. The paper describes how detailed traffic and climate data applicable to the California conditions were gathered and analyzed. The paper also presents the use of accelerated pavement testing in the calibration of response models for flexible pavements, and the important on-going efforts to collect data from in-service pavement sections. Several sites have been selected along California highways, and structural, functional, and material testing is under way. This article references a number of reports, which complement the details of the work performed.
