Accelerating solutions for highway safety, renewal, reliability, and capacity Pennsylvania Asphalt Pavement Association
What Is SHRP 2? – $232 million, federally funded research program to address critical transportation challenges Making highways safer Fixing deteriorating infrastructure Reducing congestion – Managed by TRB of the National Academies – Collaborative effort of TRB, AASHTO, and FHWA – Research phase: ; Implementation: – Aims to advance innovative ways to plan, renew, operate, and improve safety on the Nation's highways
Four Focus Areas Safety : fielding the largest-ever naturalistic driving study to reduce crashes and save lives through understanding driver behavior Renewal : making rapid, innovative construction possible for “ordinary” projects Reliability : Providing management and technical tools to reduce congestion through operations Capacity : Systematizing collaborative decision making to achieve better, faster project decisions
Renewal: Strategic Rationale Facilities are aging, users depend on them: –Renew infrastructure quickly –Have minimal impact on users –Produce long-lasting facilities We know how to do this—on special projects What keeps us from doing it consistently across the system? –Lack of standard methods, specs –Lack of reliable performance/usage information –Human/institutional challenges SHRP 2 seeks to overcome these obstacles
These products help agencies to address the need to design and construct long-lasting, durable infrastructure that requires minimal traffic disruption. B RIDGES R04.

R APID T ECHNOLOGY FOR Q UALITY C ONTROL D ATA ON A SPHALT P AVEMENTS (R06-C) Product: Model Specifications for Using Rapid Infrared and Radar Technologies for Quality Control of Asphalt Pavements During Construction. Recommendations for equipment and testing protocols and a basic training video that introduces how to use the technologies and interpret the data. Benefits: Accelerates project delivery by increasing the speed of inspection and quality assurance testing on asphalt pavements during construction. Detecting defect areas during construction allows the paving crew to adjust in real time, which avoids costly corrections and more reliably produces long-lasting pavements. Status: Research Complete. The final report, training material, video, and specifications for testing procedures are available. The model specifications are being piloted by two Transportation agencies. Revised model specifications available late 2013.

Core results with thermal profile
ADVANCED METHODS TO IDENTIFY PAVEMENT DELAMINATION (R06-D) Product: Guidelines for using two new technologies to detect subsurface delamination in asphalt pavement. Both ground- penetrating radar and impact echo and seismic analysis of surface waves accelerate data acquisition. Benefits: Accelerates assessment of pavement distress used for the selection of rehabilitation strategies. These NDT techniques improve the ability to detect a key cause of pavement failure faster, with less manual analysis, and less risk to drivers and technicians. Status: Research Complete. The final report and guidelines are available. Two prototypes are in development and pilot-test sites will be identified. Guidelines for using the technologies are being refined. The refined materials will be available late 2013.
