The second Strategic Highway Research Program (SHRP 2) focuses for a short time on a small number of large problems that confront transportation agencies: congestion, crashes, and the need to rebuild aging infrastructure. The mission is to strategically advance innovative ways to plan, renew, operate, and improve safety on the nation’s highways. To achieve this, research focuses on four related areas, including driving behaviour, highway capacity, travel time reliability, and rapid renewal methods. Now transportation agencies can more confidently use advanced methods to deliver highway renewal projects. SHRP 2 Renewal research has evaluated technologies, developed missing or strengthened weak components, tested applications, documented strengths and limitations, described selection criteria, and developed guides and models so that transportation agencies can employ a range of advanced methods and technologies to achieve rapid renewal with minimal traffic disruption as a routine practice rather than only on special or large projects. SHRP 2 Renewal products include advanced methods for bridges, nondestructive testing techniques, pavements, project delivery, and underground utilities. Tools, guides, and other products of SHRP 2 research are the focus of this document. To support their best and broadest use, these products may be published, disseminated, or hosted by partner organizations whose mission encompasses implementation, including the Federal Highway Administration and the American Association of State Highway and Transportation Officials. The objectives and methods for each research project are documented in a numbered report published by TRB and available as noted. (Author/publisher)
