This report documents the construction of hot in-place recycled (HIPR) pavement on SR 542. HIPR is a process by which rehabilitation of the existing HMA pavement occurs on site in one operation. HIPR project selection, mix design, construction and testing are described. The HIPR process successfully rehabilitated the pavement on SR 542 while using less new material than a traditional HMA mill and fill. HIPR was found to reduce initial project cost and traffic disruptions were less than with HMA paving. This project will be evaluated for five years at which time a final report documenting the HIPR performance will be produced.
