Renewal
The research objective of SHRP 2 highway renewal is to achieve renewal that is performed rapidly, causes minimum disruption, and produces long-lived facilities. A related objective is to achieve such renewal not just on isolated, high-profile projects, but consistently throughout the nation’s highway system. Projects that comprise the SHRP 2 Renewal Research Plan are shown in the Projects database, which is organized by project number. Click the project number for a description of the expected project activity.

Two weeks? That really is accelerated bridge construction
Posted October 26, 2011
Bridge designs developed in a SHRP 2 Renewal project are taking shape
over the Keg Creek in Iowa this week and next. The designs combine
several innovations into standardized approaches that can be easily
adjusted to meet the requirements for nearly any bridge project, making
the benefits of rapid renewal, economies of scale in manufacturing and
construction, reduced traffic disruption, and increased safety widely
available.
To demonstrate the design using accelerated bridge construction (ABC)
techniques, SHRP 2 is working with Iowa DOT to replace a three-span 210
ft x 47 ft bridge steel/precast modular structure with precast bridge
approaches on US 6. Using traditional construction methods would require
road closures for several months, but using the SHRP 2 design with ABC
techniques will limit the road closure to only two weeks. The Iowa DOT
is hosting a project website that
provides more information, including a live web camera of the
construction, photos, videos, plan drawings, and technical information.
SHRP 2 is also producing a documentary video to promote the innovations
being demonstrated on this project.

Preservation Approaches for High-Traffic-Volume Roadways (SHRP 2 Report S2-R26-RR-1)
Posted November 21, 2011
SHRP 2 Report S2-R26-RR-1: Preservation Approaches for High-Traffic-Volume Roadways
documents the state of the practice of preservation treatment on
asphalt and concrete pavements. Although the focus of the project was on
treatments suitable for application on high-volume roadways, this
report also discusses current practices for low-volume roadways. The
information presented is derived from a detailed survey of
transportation agencies and a review of national and international
literature. In addition, the report provides a general framework for how
best practices are identified. Finally, general guidelines were
developed for the application of preservation treatments on high-volume
roadways. Report S2-R26-RR-1 is available online as an Adobe PDF document and in hardcopy through the TRB bookstore. Presented as a separate document, Guidelines for the Preservation of High-Traffic-Volume Roadways considers traffic volume, pavement condition, work-zone requirements, environmental conditions, and expected performance.

Webinar: Part 2—Everyday Solutions: Application of SHRP 2–developed Tools in Case Studies
Posted February 1, 2012
TRB is co-sponsoring a web briefing or "webinar" on February 16, 2012, from 1:00 p.m.–2:00 p.m. EST that will explore a project conducted by SHRP 2 that focuses on accelerated bridge construction (ABC). Part 1 held in January 2012, discussed the Strategic Highway Research Program 2 (SHRP 2) ABC toolbox that was developed under project R04: Innovative Bridge Designs for Rapid Renewal. The February Part 2 webinar will describe how the toolbox was used in two bridge construction pilot projects. The first project, built in 2011, was the US 6 Bridge over Keg Creek in Iowa, which used prefabricated elements to conduct a bridge placement with only a 14-day road closure. The second project, to be let in 2012, is the I-84 Bridge over Dingle Ridge Road in New York, in which two adjacent bridges carrying I-84 will be laterally slid into place each over a weekend. Learn how the standard plans and details in the toolbox have been used to ensure success on these projects. There is no fee to register for the webinar, and one professional development hour will be provided. You can register for the webinar on the following page. Please direct questions about this webinar to abc@fiu.edu.
TRB Webinar: New SHRP 2 Tools for Underground Utility Location Data Collection and Analysis
Posted January 5, 2012
SHRP
2, in cooperation with the Federal Highway Administration (FHWA), will
conduct a webinar on February 15, 2012, from 1:00 PM to 3:00 PM EST that
will explore new tools for underground utility location data collection
and analysis. Four SHRP 2 research projects are developing innovative
tools for detecting the location and characteristics of underground
utilities and for utilizing these data. Three of these projects are
approaching significant milestones and the fourth has now been
completed. There is no fee to register for this webinar and no
professional development hours will be provided. More information is
available on the following page.

Time-Lapse Video of Keg Creek Bridge Replacement
Posted December 8, 2011
This time-lapse video shows accelerated bridge construction (ABC)
techniques being used by a local contractor with standard equipment to
replace a three-span bridge on U.S. 6 over the Keg Creek in
Pottawattamie County, Iowa. This demonstration was part of a SHRP 2
Renewal research project which created standard bridge designs that can
be adapted to a large number of bridge projects. The design scales ABC
methods to typical projects so that the benefits of faster construction
and advanced materials can be replicated wherever possible. The goal is
to make ABC techniques a standard part of bridge construction. The video
is available on the following page.
