Develop Maintenance Strategy Selection Procedures for Pavements Incorporating Semi-Rigid or Chemically Stabilized Layers (0-1722-2)

TxDOT does not currently have a formal maintenance strategy selection procedure for pavements which have semi-rigid or chemically stabilized layers. The approach used was to interview experienced TxDOT personnel in each district and to determine the appropriate maintenance treatments and timing in that district for a variety of expected situations and conditions.|The result of this research 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. A computer program and user's manual were developed to assist in treatment selection.
