Pavement Condition Index (PCI) and Pavement Surface Evaluation and Rating (PASER) surveys have been utilized for nearly 50 years to rate the condition of a network of pavements and to efficiently plan maintenance and rehabilitation. Whether the surveys are conducted via foot-on-ground or by inspection of digital data, the process is typically reiterated from one network to the next and is largely straight forward. However, the US Forest Service has a network of pavements that is spread across the entire country with hundreds of thousands of miles in between their routes, so traditional methods are not economically practical or timely. Utilizing ARA’s newly developed, portable digital survey system, PaVision, and Rival Solutions Rubix software for PASER surveys, ARA traversed the remote areas of California, Oregon and Washington to successfully collect nearly 2,500 miles of the Forest Service’s network in just 3 months’ time.

With the goal of updating their pavement management program, the US Forest Service contracted ARA to conduct PCI surveys, PASER surveys, high-def imagery and video, and ride quality data in Regions 5 and 6 of their national network of forests. Region 5 includes all National Forests in the state of California and Region 6 includes all of Oregon and Washington. With approximately 15,000 miles of dead heading between all of the routes, a tremendous amount of planning and coordination, along with a modern approach to pavement management made this project a success.
