Figure A.14. IRI performance of Buchanan County W-45 County W-45 was found to have performed well at 13 years of service, featuring a PCI of 79 in/mi when last measured in 2014. Some distress was associated with random longitudinal cracking caused by failure to establish the longitudinal joint during construction. This project was initially selected for field review to investigate why PCI and IRI appeared to have rebounded significantly; between 2008 and 2011, PCI increased from 72 to 79 and IRI fell by nearly 20 in/mi.
