Abstract:

Prior to this effort, Mississippi's MEPDG climate files were limited to 12 weather stations in only 10 countries and only seven weather stations had over 8 years (100 months)of data. Hence, building MEPDG climate input datasets improves modeling accuracy and geographic coverage.

The sensitivity analysis examined how the improved climate data input files impacted the pavement performance prediction. The analysis measured the impact of the three different climate input files (MEPDG, Historic, and Virtual) on three common types of pavements (jointed PCC, Thick HMA, and thin HMA) used in Mississippi. The analysis showed that repeating the limited data in the MEPDG climate input files to predict pavement distress over a typical 20 to 40 year analysis period resulted in significantly higher predicted distress in some cases. The sensitivity study determined that the resources used to build the improved climate files were an appropriate effort with a measureable long-term benefit.
