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: 2006-2015; Implementation: 2012-2017
– 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
Renewal Topics
• Bridges
• Project Management
• Utilities and Railroads
• Nondestructive Testing
• Pavements

and fatigue risk management practices and techniques; A toolkit
for managing workforce fatigue in the rapid renewal
environment; Model training and outreach materials to assist in
future implementation.
Benefits: Tools to manage workforce fatigue and increase
worker safety will help transportation agencies reduce the risks
of accelerated schedules, longer day shifts, night and weekend
work, and work conducted in protected zones adjacent to traffic
that are often associated with rapid renewal projects.

RAPID TECHNOLOGY FOR QUALITY CONTROL
DATA ON ASPHALT PAVEMENTS (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.

ADVANCED METHODS TO IDENTIFY
PAVEMENT DELAMINATION (R06-D)
Product: Guidelines for using two new technologies to detect
subsurface delamination in asphalt pavement. Both groundpenetrating 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.
