Case Study: Developing a Surface Condition Indicator from Laser Crack Measuring System Data for Pavement Asset Management

The benefits of adopting the SCI for setting performance measures and communicating trade-offs in investing for pavement preservation projects. SMHI’s SCI values range from 0 through 100+ in a progression that reflects the amount and severity of pickouts and cracking that develops as pavements age. SCI60 values are categorized as good, fair or poor. Pavement segments with fair SCI60 are light treatment preservation candidates. Pavement segments in the poor category are too late for a light preservation treatment. SCI60 values over 45 require a heavy preservation treatment.
