City of Lincoln
2005 Media Releases
Mayor Coleen J. Seng announced that the City is implementing a pavement management system to help extend the life of City streets. Applied Research Associates (ARA), a pavement engineering and management firm from Illinois, began surveying more than 1,500 miles of city streets this week with a specially equipped van. Over the next five to six weeks, ARA will survey all major arterials and residential streets.
“It is very important that we make the best use of the funds allocated for street maintenance and resurfacing,” said Mayor Seng. “This technology is a very valuable tool. Once implemented, the system will give us the information we need to extend the life of our streets.”
The assessment collects high-quality digital images of the pavement surface and measures the number and extent of defects. The van also will record the amount of roughness and rutting along each street surface. The van is equipped with navigation and global positioning systems (GPS) to map its position.
Once all of the digital images are processed for each of the 15,000 pavement sections in the street network, the street data are entered into a pavement management software program designed for the City of Lincoln’s unique combination of traffic, climate and paving materials. The software will then be used to select the most appropriate maintenance or repair method for each street to extend the life of the pavement.
In addition to the condition survey, ARA also will simultaneously capture high resolution digital images of sidewalks, curbs, gutters, handicapped ramps, street trees and fire hydrants. These images can then be analyzed for GPS coordinates and other key attributes to help the City maintain its entire roadway infrastructure.
The system will cost about $420,000 and will produce savings by helping to identify the best places to spend street maintenance funds. “We expect to recoup that expense fairly quickly because this system will tell us where we can make minor repairs now to avoid expensive major reconstruction later,” said Assistant City Engineer Karl Fredrickson.
