Abstract:There are an estimated 3.6 million road opening permits issued nationwide each year (Jarnecke and Pollock, 2017). While advanced planning and coordination with other planned roadway work can reduce impacts, open utility cuts are often unavoidable. As a result, local public agencies face the challenge of ensuring pavements are repaired properly after the installation or repair of subsurface utilities creates open cuts in the roadway. Repairs can result in weakening of the pavement foundation, decreasing the expected service life and leading to deterioration of the repaired area before the surrounding undisturbed pavement. Performance of repaired areas are influenced by several factors such as backfill materials, compaction of the backfill, season in which it was completed, and compaction of the asphalt surface. There is a need to develop a best practices matrix which can be used to improve the long-term performance of pavement repairs of open utility cuts, specifically in Northern Ohio.
