Abstract
Virtual site visits and interviews of five key State Departments of Transportation (DOTs) plus the two Federal Lands Highway Divisions, along with material producers and paving contractors that served these agencies were conducted to learn more regarding successful use of cold asphalt and hot in-place recycling technologies. Practices investigated were project selection, recycling technology selection, structural pavement design, materials, mixture design, field construction and acceptance, quality control, curing and opening to traffic, lessons learned, pavement performance, contractor perspectives, and agency best practices were collected and synthesized in this report. Some agencies used a single recycling technique while others used multiple. The summary of this information includes practices used by State DOTs to implement cold asphalt and hot in-place asphalt recycling technologies. Examples of positive practices, lessons learned, and challenges from States and Federal Lands Highway Divisions are presented.
