The resulting safety, economic, financial, management, environmental, aesthetic, and technological challenges are formidable enough for an individual project; meeting these challenges on a nationwide scale will require the development of an entirely new way of approaching highway renewal. shrp 2 renewal research The strategic objectives of the SHRP 2 Renewal focus area address three needs: (a)

Full Road Closures Reduce Project Duration in Several States In certain circumstances, full road closure can be less disruptive than attempting to maintain traffic through a construction area: • The Delaware Department of Transportation (DOT) rehabilitated a 6.1-mile section of roadway between Wilmington, Delaware, and the Pennsylvania state line.

Bridges and roads that last longer mean billions of taxpayer dollars saved, as well as less frequent disruption from future renewal activities. Tactics Renewal time in the field can be defined as the time it takes to complete those on-roadway construction activities that affect traffic flow and the communities and businesses that rely on the roadway for services.

From page 48... ...
The SHRP 2 Renewal plan will address prefabrication, modular construction, and innovative installation strategies for bridges and pavements as part of this tactic. Rapid construction systems such as modular pavements and prefabricated bridges or bridge elements can help reduce traffic disruption by permitting elements of pavements, bridges, and other roadway infrastructure to be built off-site and then installed in assembly-line fashion.

Research conducted in support of this tactic focuses on developing performance-based specifications that afford the contractor greater construction control while managing agency risk, as well as on reexamining the allocation of risk inherent in the special nature of accelerated construction. Tactic 5: Improve Customer Relationships Planners of renewal projects must accommodate the needs and rights of utilities and railroads that share roadway rights-of-way to keep renewal projects on schedule and budget.

Products in the project delivery category support the three objectives of the Renewal focus area by addressing construction and asset management, quality control, and institutional arrangements between transportation agencies and their many partners. Products under each category are described below.

SHRP 2 will develop design procedures, standard plans, design examples, contracting tools, and training materials to facilitate the use of promising bridge innovations. While pavement and bridge technologies may be the most obvious elements of highway renewal, other less visible elements are just as important.

From page 52... ...
Prefabrication off-site in a controlled environment can improve con structability by reducing impacts of weather and can enhance construction quality by ensuring more consistent materials and procedures. Standardization of identi cal components can reduce initial construction costs, and higher quality lowers life-cycle costs.

From page 53... ...
Project Delivery Products SHRP 2 products in the project delivery category address barriers to rapid renewal that exist beyond the design and construction activities directly associated with a given renewal project. These barriers relate to management and institutional issues that must be addressed for rapid renewal to be applied more widely.

From page 54... ...
Use of some of the pavement, bridge, and geotechnical technologies described under the technology product category will require additional nontechnological support. For example, the benefits of composite and modular pavements and innovative bridge elements are predicated on their long-term performance.

From page 55... ...
Incentives for agency personnel to use the products of Renewal research include minimizing traffic disruption; providing better facilities; improving life-cycle costs; streamlining project delivery; and achieving better working relationships with utilities, railroads, and adjacent businesses and property owners. Agency personnel will not assume the risks of innovation unless they develop a high level of trust in the innovation and in those promoting it.

If efforts to implement SHRP 2 Renewal products do not recognize and accommodate the special role of standards, widespread implementation may founder. An intensive effort to develop consensus standards for the application of SHRP 2 Renewal products must proceed among standards-setting organizations in parallel with other implementation activities.

From page 57... ...
It may be helpful to describe alternative scenarios to highlight the benefits of differing strategies and to solicit their input into decisions closely affecting them. Other important potential users of Renewal products are teachers, professors, and researchers.

From page 58... ...
conclusion Incorporation of the SHRP 2 Renewal research products into standard business practices will be challenging but rewarding. What were once viewed as highly innovative measures employed for use only on special projects will become the normal way of doing business.
