Abstract:The Texas Department of Transportation does not currently have a formal maintenance strategy selection procedure for pavements that have semi-rigid or chemically stabilized layers. Researchers interviewed experienced TxDOT personnel in each district to determine the appropriate maintenance treatments and timing in that district for a variety of expected situations and conditions. The result of this project was a set of treatment assignments for each district and for airports, for a matrix of expected conditions including: distress type, severity, and quantity; traffic level or importance; rate of development; and purpose of the treatment. The research team developed a computer program and user’s manual to assist in treatment selection.
