The time it takes a pavement to return to the condition rating it had just prior to a treatment application. For example, before a treatment was applied, if a pavement was rated as a 60 PCI and it took 5 years to drop back to a 60 PCI, it can be said that the treatment provided 5 years of life extension.
The life extension of a given treatment varies greatly depending on roadway condition, quality of treatment, climate, and a number of other factors. Additionally, there are many best practices road owners can implement to achieve better than average life extension.
To provide conservative estimates, all calculator tools throughout the site use the median range of average performance. See the
section of the
Treatment Resource Center
for detailed Life Extension information on each treatment, and visit the
Best Practice section
to learn how to maximize the life of each treatment.
