The proposed Mechanistic–Empirical Pavement Design Guide (MEPDG) developed under the NCHRP Project 1-37A initiative is a significant advancement in pavement design. However, it is substantially more complex than the 1993 AASHTO design guide and it requires significantly more input from the designer. Some of the required data either are not available or are stored in locations not familiar to designers. In addition, many data sets need to be preprocessed for use in MEPDG. Thus, there was a need to study the data requirements for MEPDG and produce a centralized database system to aid designers. This paper describes the development of a comprehensive database that can be used to store and process climate, traffic, material, and performance data for the state of Arkansas. The tasks undertaken were to (a) identify all the necessary input and analysis parameters required, (b) develop the database structures for uploading the required data, (c) locate the available data sets and begin populating the database, and (d) develop a data interface to the MEPDG software. The completed database will improve the management and accessibility of the MEPDG input data, and its completion is a critical step before the calibration and implementation of MEPDG.
