PSI was selected to develop a pavement condition index (PCI) rating of 823 centerline miles of streets throughout the Municipality of Anchorage in fulfilment of the Governmental Accounting Standards Board Statement No. 34 (GASB 34).
The unique aspect of this project was the short timeline and narrow window in which PSI was able to complete the work. Pavement condition surveys are best performed in clear weather conditions when the roadway surface is dry and pavement distresses are clearly identifiable. PSI was authorized to mobilize to perform the survey in September, with only weeks before the Anchorage streets would be covered in snow. Always responsive to the needs of our clients, we deployed a team of four pavement raters and utilized the power of handheld tablets with GPS capability to record pavement distress data and develop PCI ratings directly in the field. Using a statistical sampling method according to ASTM D6433, Anchorage streets were assessed using standardized definitions for pavement distress type, quantity, and severity before the first snow fell.
