• Abstract:
  Premature pavement failures have occurred on several widening projects, including shoulder widenings, conversion of two-lane roadways to Super 2 sections, and other safety enhancements. Repairing these early failures is time-consuming, expensive, disrupts traffic, and poses safety hazards. Key contributing factors include poor-quality materials, poor joint construction, and inadequate drainage. These issues could have been avoided through proper pavement condition assessment, design, and construction practices, but detailed guidance on which methods to employ and which can be project specific is not readily available to district personnel. Therefore, there is a need to document and implement better widening practices across TxDOT.
