PERFORMANCE AND COST OF SELECTED HOT IN-PLACE RECYCLING PROJECTS
The objective is to summarize the extent of use and resulting performance of hot in-place recycled (HIPR) asphalt pavements. Most types of surface distress in an asphalt pavement can be corrected by HIPR provided the pavement has adequate structural integrity. When all factors are considered, a savings of up to 50% can be achieved when a 25-mm (1-in.) HIPR layer is compared with cold milling and placement of a new 25-mm overlay. Careful consideration must be given to preparing specifications that are relevant to the intended construction program. Specifications should clearly describe an acceptable finished HIPR product. In some cases, it may be necessary to describe certain elements of the equipment required to furnish the desired product. A telephone survey of all 50 state highway agencies was conducted to determine the extent of use of HIPR and type of processes being used. The survey revealed that fewer than 10 state agencies are routinely using HIPR. Most states have tried HIPR but only experimentally. Many states have no experience with the new remixing processes.
