Data needs and implementation of the Pavement ME Design

ABSTRACT Highway agencies across the United States are moving from empirical design procedures towards the mechanistic-empirical (ME) based pavement design. The Pavement ME Design presents a new paradigm shift with several important improvements, and it requires extensive data needs for full implementation. Based on extensive research conducted in the past two decades, this paper provides a comprehensive review of the data needs and processes related to the Pavement ME Design. A full spectrum of the art-of-the-state implementation activities in sensitivity analysis, climate data, traffic inputs, material characterization, and local calibration approaches and practices have been investigated. Special emphasis is on Weigh-in-Motion (WIM) data processing algorithms and software developed by the authors, and the interpretation of the damage models in the Pavement ME Design. The efforts in this paper can aid in the continuous implementation and enhancement of the Pavement ME Design.
