Impact of Design Features on Pavement Response and Performance in Rehabilitated Flexible and Rigid Pavements

Appendix E. Performance and Input Database for MEPDG Analysis

This section is an electronic appendix and explains the electronic file structure and fields in the various tables in the database. Performance data of SPS-5 and SPS-6 experiments were compiled into this database for comparison with MEPDG analysis results. The database also contains the input data used in the MEPDG analyses. The data provided in this database were used during phase 2 of this project. Moreover, it allows for the creation of the input files for all sections in SPS-5 and SPS-6 experiments.

Performance Data

Performance data for all SPS-5 and SPS-6 sections are stored in the database. These data were used in phase 2 of this project. The performance data tables are labeled "Performance" followed by the distress type. The following lists the tables and respective fields:

Table name: Performance_Roughness

Table name: Performance_Rutting

Table name: Performance_Fatigue_cracking

Table name: Performance_Longitudinal_cracking

Table name: Performance_Transverse_cracking

Table name: Performance_Faulting

Table name: Performance_PCC_slab_cracking

MEPDG Input data

Data used to create the MEPDG run files are stored in two tables in the database. One table contains the data for SPS-5 sections, and the other contains data for SPS-6 sections. Additional input data could not be placed in the database file and were stored in folders to support the main database.

Traffic data for monthly adjust factors (MAFs) and axle load factors (ALFs) were stored in files already in the format required by MEPDG. These files are located in the folder called "Traffic-Supporting Files." Climate files are also stored in the "Climate-Supporting Files" folder. References to the files stored outside the database are located in the appropriate fields in the MEPDG inputs table in the database.

The following tables and respective fields were populated and stored in the database:
