Present Serviceability Index (PSI) The Present Serviceability Index (PSI), one example of a condition rating system, is a 0 to 5 scale that was originally based on a panel of raters who, between 1958 and 1960, rated various roads in the states of Illinois, Minnesota, and Indiana. Pavement quality evaluation by PSI (Present Serviceability Index) is based on the data of pavement roughness and damages However, PSI is affected by subjective factors as the determination of the proportions of cracks, repairs is analyzed through images or by directly surveying sites, while IRI is not affected by subjective factors when direct.

Pavement performance modeling or pavement deterioration modeling is the study of pavement deterioration throughout its lifecycle The health of pavement is assessed using different performance indicators Some of the most wellknown performance indicators are Pavement Condition Index (PCI), International Roughness Index (IRI) and Present Serviceability Index (PSI), but sometimes a single. The PSI is just a measure of the current overall rating of a section of highway based upon visual observation The scale goes from 5 (perfect) to 0 (awful) It is similar to the 100 point rating scale used in our CAMPRS program. The Iowa Department of Transportation has been determining a present serviceability index (PSI) on the primary highway system since 1968 A CHLOE profilometer has been used as the standard for calibrating the Roadmeters that do the system survey The current Roadmeter, an IJK Iowa DOT developed unit, is not considered an acceptable Roadmeter for determining the FHWA required International.
