Mayor Chris Beutler today said updating the City's pavement condition survey will provide important data on how to prioritize street repair projects. A specially equipped van from IMS Infrastructure Management Services is now surveying arterial and other major streets to help the City update its pavement management system to extend the life of City streets.
"Pavement is one of the City's largest infrastructure investments," Mayor Beutler said. "It's estimated that the cost of rebuilding pavement in Lincoln would be more than $1.5 billion. The pavement survey now under way helps us determine those areas where repairs now will prevent more costly reconstruction down the road. The goal of our pavement management system is to make the best use of our limited funding to keep our streets in good condition."
A complete survey of all Lincoln streets was conducted in 2005 by Applied Research Associates (ARA), which also updated the survey of major streets in 2008. Thomas Shafer, Design and Construction Manager for the Public Works and Utilities Department, said the City's pavement management system calls for updates of major streets about every three to four years, and full surveys of all streets about every ten years. The survey now under way will cover about 582 lane miles of major streets at a cost of cost about $193,650.
IMS began the survey January 25, and it is expected to take about three to four weeks to complete depending on weather. The process collects high-quality digital images of the pavement surface and measures the number and extent of defects. The van also records the extent of roughness and rutting along each street surface. The van is equipped with navigation and global positioning systems (GPS) to map each street section surveyed.
Once all of the digital images are processed for each pavement section in the street network, the information is entered into a pavement management software program designed for the City of Lincoln's unique combination of traffic, climate and paving materials. Analyzing the data and uploading it into the City's system will take about two to three months.
The city now has nearly 2,800 lane miles of streets. Shafer said the City plans to spend about $35 million on street construction this summer, and previous condition surveys have helped the City prioritize that work.
