The two pavement sections located in CA exhibited insignificant variation in thermal cracking, although one of them had an additional 1.5” (38 mm) dense-graded asphaltic concrete (AC) layer. The in-state analysis focused on comparing the pavement sections located in the same state. The performance of the pavement sections was evaluated in respect of thermal cracking and rutting resistance. Two levels of analysis-in-state analysis and cross-state analysis-were performed for these pavement sections to determine the impacts of traffic and climate conditions. Two of them are flexible pavement sections, whereas the other two are composite pavement sections. The study presented in this paper analyzed four long-term pavement performance (LTPP) test sections located in the states of New York (NY) and California (CA).
