A 2020 Pavement Management Report for the University of Illinois at Urbana-Champaign campus streets, by Applied Pavement Technology, Inc., stated: 

“Overall, the 2020 area-weighted PCI of the university-maintained roadways is 65. Condition results from the previous [pavement] projects for the university can be compared to the results of this study to track how the pavement network is performing between PCI inspections. The overall area-weighted PCI was 59 in 2009, and 65 in 2016 and 2020 (excluding brick and gravel). It is interesting to note that the overall PCI remained unchanged from 2016 to 2020, despite annual spending of about $1.5 Million. …  The percent of pavement above a PCI of 70 has increased to 50 percent (it was 37 percent in 2009), while the percent of pavement with a PCI below 40 has remained near 25 percent for all inspection years.  Since the percent of pavement in the mid-range of the PCI scale (40 to 70) has decreased from 39 percent to 25 percent since 2009, it appears most of the major work that has occurred since 2009 has focused on improving pavements in this condition range.”
