Pavement Replacement Using a Precast Concrete Pavement System on I-15 in Ontario

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 California Department of Transportation was awarded a $5 million grant to showcase and demonstrate the use of precast concrete pavement system (PCPS) technology for the replacement of concrete slabs on Interstate 15 in Ontario, CA. The project involved the rehabilitation of 4.7 miles of roadway including 696 PCPS slab installations. The rehabilitation project provided the opportunity to evaluate PCPS alongside traditional cast-in-place slab replacement methods. In addition, the project involved the use of other innovative technologies. The design phase of this project utilized CA4PRS analysis to optimize construction staging plans and Dynameq to characterize traffic flow during construction and rehabilitation activities. Also, a road safety audit was performed in the early stages of the construction to critically examine safety considerations in various design and planning elements.

This report documents the details of this project, including a description of the applied PCPS technology and its design, construction staging techniques and maintenance of traffic, slab installation, and performance evaluations and economic analysis. This report also contains other items relevant to HfL projects, including a description of HfL goals, technology transfer activities on the project, and a detailed analysis of data to evaluate if the HfL goals were satisfied.

This project serves as a great example of the successful use of multiple innovations on a large scale project. The project also demonstrates the key factors for success: vast breadth of knowledge and expertise required, the importance of planning and attention to details, and the significance of good communication across various divisions within an agency. Specifically, in the case of PCPS, this project achieved tremendously high production rates for slab installations in nighttime work windows. Besides the initial trial installations behind k-rails, all PCPS installations performed in nighttime work windows did not require closure of more than 2 lanes, which was compensated with the addition of two median lanes in the project. Given the construction staging plans and the lane closure patterns, the economic analysis shows no significant cost implications due to the use of PCPS technology for slab replacement.
