Best Practices for Level-Up Patching Operations
Level-up patching is a common corrective maintenance activity in Texas performed by most districts. It involves laying down a thin asphalt mix layer over an existing pavement in areas of sagging or rutting to improve the ride score and reduce pavement roughness. Level-up patching is used as a surface preparation step prior to another surface treatment operation or as a final exposed surface. This handbook describes in-detail the best practices of level-up patching, as established from a thorough literature review and information collected from various TxDOT districts through survey questionnaires and site visits. This handbook is intended for use by TxDOT field personnel as well as contractors that perform this work for TxDOT.
