The goal of our pavement management system is to make the best use of our limited funding to keep our streets in good condition. Lincoln has about 2,800 lane miles of streets, and it is estimated that the cost of rebuilding pavement in Lincoln would be more than $1.5 billion. Maintaining an updated survey of pavement condition provides important data on how to prioritize street repair projects.
To conduct a pavement condition survey, a specially equipped van 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.

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.
