Figure 1: Pavement Condition Index

Posted: Wednesday, August 15, 2012 4:10 pm

According to the International Slurry Surfacing Association's (ISSA) Pavement Condition Index (PCI), a road that receives three preservation treatments over a 25-year period at $2 per square yard will remain in good condition for a total cost of $6 per square yard. If the road is left untreated for 11 years and pavement preservation is used as reactive maintenance, the cost will be approximately $4 per square yard. Waiting this long to apply a treatment generally leads to a deteriorated road base structure, so the reactive maintenance treatment will only last about four years, when it will require yet another treatment. In comparison, if nothing is done for 12 or more years, a mill and fill or a full rehabilitation will be required at a cost upwards of $12 to $16 per square yard. The PCI was developed originally by the U.S. Army Corps of Engineers.
