Foreword

The purpose of the Highways for LIFE (HfL) pilot program is to accelerate the use of innovations that improve highway safety and quality while reducing congestion caused by construction. LIFE is an acronym for Longer-lasting highway infrastructure using Innovations to accomplish the Fast construction of Efficient and safe highways and bridges.

Specifically, HfL focuses on speeding up the widespread adoption of proven innovations in the highway community. Such “innovations” encompass technologies, materials, tools, equipment, procedures, specifications, methodologies, processes, and practices used to finance, design, or construct highways. HfL is based on the recognition that innovations are available that, if widely and rapidly implemented, would result in significant benefits to road users and highway agencies.

Although innovations themselves are important, HfL is as much about changing the highway community’s culture from one that considers innovation something that only adds to the workload, delays projects, raises costs, or increases risk to one that sees it as an opportunity to provide better highway transportation service. HfL is also an effort to change the way highway community decisionmakers and participants perceive their jobs and the service they provide.

The HfL pilot program, described in Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU) Section 1502, includes funding for demonstration construction projects. By providing incentives for projects, HfL promotes improvements in safety, construction-related congestion, and quality that can be achieved through the use of performance goals and innovations. This report documents one such HfL demonstration project.

16. Abstract

As part of a national initiative sponsored by the Federal Highway Administration under the Highways for LIFE program, the Utah Department of Transportation (UDOT) was awarded a $750,000 grant to demonstrate the use of proven, innovative precast concrete pavement system (PCPS) technology to deliver this project in less time and with less impact on motorists than conventional construction.

This report details the PCPS innovations used to replace the existing deteriorated concrete pavement during 7- to 10-hour nighttime lane closures. Traditional construction practices of cast-in-place full-depth repairs would have required closures of 7 to 10 days, greatly impacting traffic during peak hours on this urban belt route. Traditional construction practices would have resulted in delays of 3,608 vehicle-hours with one-lane closure and 122,704 vehicle-hours with two-lane closures per day on Monday through Thursday and 1,255 vehicle-hours with one-lane closure and 106,820 vehicle-hours with two-lane closures on Friday. Using PCPS and nighttime construction reduced vehicle-hours of delay to zero.

UDOT learned several valuable lessons on rehabilitation using PCPS. The project was completed with minimal disruption to the traveling public, improved worker and work zone safety, and substantial reduction in construction time that affected traffic. The experience gained on this successful project will help UDOT refine its accelerated pavement construction processes and use them in other situations where traffic impacts are a major concern.
