• May be applied individually or in combination with products from different programs.

• Are easy to learn more about through Websites, Webinars, demonstrations, and peer-to-peer programs.

• Are supported by funding and assistance opportunities that can help your agency quickly and confidently apply innovations to current challenges.

3


State-Based Transportation Innovation Councils

• Provides state-based leadership for the innovation strategies and solutions

• Helps facilitate deployment of innovation initiatives

• Engages all the key stakeholders in a state

4


What is SHRP2?(Second Strategic Highway Research Program)

• Products developed from objective, credible research

• Solutions that respond to transportation community challenges – safety, aging infrastructure, congestion

• Tested products, refined in the field

Save lives. Save money. Save time.

SHRP2 Solutions offer new technologies and processes to enhance the efficiency of transportation agencies

5


Why is SHRP2 Important?

SHRP2 Solutions have the power to change the way transportation agencies do business.

Tools for the Road Ahead

By providing new research-based tools and innovative products and processes…

That will create more efficiencies and a smarter use of state and federal investments of taxpayer dollars.

6


Safety: fostering safer driving through analysis of driver, roadway, and vehicle factors in crashes, near crashes, and ordinary driving

Renewal: rapid maintenance and repair of the deteriorating infrastructure using already-available resources, innovations, and technologies

Capacity: planning and designing a highway system that offers minimum disruption and meets the environmental and economic needs of the community

Precast Concrete Pavement – R05

ChallengeCongestion and traffic delays due to roadway repair and rehabilitation are a major source of irritation for drivers.Solution • The SHRP2 PCP Solution offers a

series of guidelines and model specifications to help agencies effectively design, fabricate, and install long-life PCP systems.

• Coupled with shorter construction-related closures and potential long-life performance, PCP offers transportation agencies many significant advantages.

15



Background Information on the Development of R05 • FHWA has conducted proof-of-concept pilots for PCP with highway

agencies since 2002.

• International, domestic, and entrepreneurial efforts have concurrently advanced interest in and use of PCP systems.

• SHRP2 Project R05 on PCP – Summarized currently available information and experience for PCP systems; Documented the performance of some 14 PCP projects constructed throughout the US; Facilitated improved PCP design and construction procedures for use by highway agencies; and, Assembled design procedures, model specifications, and guidelines for all PCP-related activities.

16



Benefits Derived from Use of PCP• Short-duration work zones – No on-site finishing and curing.

• Reduced user delays – PCP immediately ready for traffic.

• Improved safety/satisfaction – Workers and highway users.

• Long-life performance – High-quality precast concrete.

• Reduced maintenance – Strength and durability assured.

• Sustainability – Economic, social & environmental benefits.

SHRP2 Project R05 Report

FHWA’s activities to implement PCP are based on the report –“Precast Concrete Pavement Technology” [S2-R05-RR-1] http://onlinepubs.trb.org/onlinepubs/shrp2/SHRP2_S2-R05-RR-1.pdf

The R05 report presents Guidelines for both jointed and prestressed PCP systems, as follows:• PCP Design• PCP Fabrication• PCP Installation• PCP Project Selection• PCP System AcceptanceAlso, Model Specifications for both systems: http://www.trb.org/StrategicHighwayResearchProgram2SHRP2/Pages/R05-Model-Specifications-718.aspx

18



SHRP2 R05 Report Available PCP technologies are included in the report under topics of jointed systems and prestressed systems.

Jointed Panels (JPrCP) – Used for intermittent repairs and continuous rehabilitation activities. Load transfer between panels and to the existing pavement is achieved with dowels.

Prestressed Panels (PPCP) – Used singly or as multiple panels post-tensioned together on site in lengths of 150 feet or longer. Joint faces between panels provide load transfer. Longitudinal thermal movements are accommodated with expansion joints.

19



Applications of PCP Applications of PCP can include, but are not limited to:• Night-time work windows on high-volume traffic highway facilities to reduce traffic congestion, improve safety, and achieve long-life performance. • Full-depth repairs, rehabilitation, and/or new construction. • Replacement of mainline pavements, ramps, underpasses, bridge approaches, and high-volume urban intersections. • Overlays or inlays of existing pavement. • Increasing load capacity while maintaining existing pavement cross-sections (a feature of prestressed concrete).

Design of PCP Design Assumptions –• JPrCP behavior will be similar to a cast-in-place jointed

concrete pavement.• PPCP behavior will be similar to a cast-in-place prestressed

concrete pavement. Long-Life Performance –• Initial service life of 40+ years.• No materials-related distress or premature failures.• Reduced potential for cracking, faulting, and spalling.• Desirable smoothness and surface texture retained with

minimal need for intervention. Critical requirements – Load transfer and panel support.

24



Fabrication of PCP Precast concrete is an established technology long in use for bridges and other structures. For pavement applications, a check-list such as the following may be helpful:• Precast plant certification – National Precast Concrete

Association and Precast/Prestressed Concrete Institute. • Concrete requirements – Strength requirements typically are

exceeded; however, testing for entrained air and for alkali-silica reactivity may be additional requirements.

• Panel tolerances suitable for pavement application.• Surface texture as delivered from the precast plant. • Pre-tensioning and post-tensioning requirements (for

prestressed concrete panels). 25



Construction of PCP JPrCP – Installation staging and lane closures; removal of distressed concrete; base preparation; bedding placement; load transfer provisions; panel placement; dowel slot grouting or patching; subsealing and joint sealing; surface grinding.

PPCP – Panel–base interface treatment; panel placement; temporary and final posttensioning; expansion joint panel installation; temporary transition panel installation; subsealing and conduit grouting; anchoring; surface grinding.

26



Project Selection - While PCP can be used on any pavement project, typical warrants for its use are:

• High-traffic locations. • Long-life pavement performance is desired. • Work zones limited to short duration (e.g., overnight).• Roadway opened to traffic immediately following installation.

PCP System Approval - The approval process consists of two essential parts: • Submittal and review of fabricator shop drawings and

standard installation procedures.• Construction and evaluation of a PCP trial installation.

27


Assistance Opportunities

• FHWA with support from consultant:

– Webinars, presentations, and workshops.
