Sensitivity of Predicted Pavement Performance to Climate Characteristics
The analysis methodology in the new AASHTO mechanistic-empirical pavement design guide (MEPDG) places great emphasis on the influence of climate on pavement performance. However, the effects of climate properties on pavement performance have not been systematically and rigorously quantified to date. A suite of one at a time (OAT) sensitivity analyses spanning three climate regions and three traffic levels has been performed to evaluate quantitatively the influence of individual climate characteristics on flexible and rigid pavement performance as predicted by the MEPDG. Overall, the sensitivity analyses found that the average annual temperature and the average annual temperature range are the most sensitive inputs for both flexible and rigid pavements, followed by percent sunshine and wind speed. The sensitivity of JPCP slab cracking to average daily temperature range was also very high. The sensitivity of MEPDG predicted pavement performance to precipitation and relative humidity were found to be very small in all cases.
