Abstract: The M-EPDG (Mechanistic-Empirical Pavement Design Guide) is gradually accepted by pavement engineers in predicting pavement service life in many states. However, lacking of calibration data is one of the major barriers for the application of M-EPDG. Climate data is one of the important data for the M-EPDG implementation. Therefore, new sources of climate data need to be discovered. The LTPP (Long Term Pavement Performance) program climatic data could be a reasonable complement of the M-EPDG climatic database. In this paper, a method of predicting pavement service life using M-EPDG with LTPP climatic database is proposed.
