This report documents the analysis of data collected through the Long-Term Pavement Performance (LTPP) program to characterize the effects of dowel misalignment on concrete pavement performance. The objective of this research was to measure the alignment of dowels at the transverse joints of in-service pavements. This report documents this information on a State-by-State basis. Data were used to evaluate typical distribution of various types of misalignment and analyze how misalignment relates to pavement performance factors such as cracking, faulting, and spalling.
