Considerations for Rigid VS. Flexible Pavement Designs when Allowed as Alternate Bids: Technical Report

摘要

This report documents the research conducted for the Texas Department of Transportation (TxDOT) concerning the use of pavement alternates. The scope of the project includes reviewing the state-of-the practice in methods used for pavement type selection, interviewing TxDOT key personnel with experience in developing pavement structure alternatives, conducting a side-by-side comparison of current TxDOT pavement design methods, developing guidelines with a protocol for considering rigid versus flexible pavement designs when allowed alternate bids, and developing the Alternate Pavement Design Analysis Tool (APDAT) for pavement type analysis.
