ABSTRACT
ABSTRACT: The objective of the paper is to present the results of the verification of the predicted rutting, alligator cracking, longitudinal cracking, thermal cracking, and roughness (IRI) using the Mechanistic-Empirical pavement design guide. In this study, nine Long Term Pavement Performance (LTPP) and sixteen non-LTPP sections in the state of New Jersey were evaluated. The level 3 material input and level 2 traffic input were used during analysis. The input data and measured field performance data were collected from multiple sources. The analysis showed that the average difference between measured rutting and the average predicted asphalt concrete layer rutting was statistically insignificant at 95% confidence level. The measured longitudinal cracking, thermal cracking and roughness (IRI) were statistically similar to the predicted values. In addition the difference between measured and predicted alligator cracking was reasonable considering the error of field measured data, and prediction error due to level 3 material input.
