Guidelines for using existing pavements in rapid construction to extend pavement life and save money.
Pavement Renewal Solutions (R23)
Highway agencies need guidance to help better understand when and where it can be beneficial to use existing pavements to speed rehabilitation project delivery. Use of existing pavement can reduce cost; however, it is not always a viable solution. By being able to identify projects where this technique can be successful, highway agencies can apply the process with more confidence, and reap the benefits of lower cost, and more rapidly rehabilitated facilities.
An interactive web-based pavement design scoping tool provides much-needed guidance for deciding where and under what conditions to use existing pavement as part of roadway renewal projects. It includes approaches for employing existing pavements in-place to ensure longer service life for roads using asphalt, concrete, and innovative materials. The product also identifies new alternatives to renewal approaches; and examines the advantages and disadvantages of each approach, the circumstances under which each should be considered, different construction techniques, and methods for integrating recycled materials with adjacent materials and road structures.
This guide will help transportation agencies make better decisions with regard to pavement renewal projects by using existing pavement as part of the design. Transportation agencies, drivers, highway workers, contractors, and taxpayers will benefit from time savings based on rapid reuse of existing materials, reduced costs for new pavement, and an accelerated construction process. Washington DOT has utilized the recommendations offered in this guide, and has realized a 30 percent cost savings and a 50 percent reduction in user delay costs over the life of the new pavement. This approach delivers long-lasting value by promoting durable and dependable roads, while reducing the environmental footprint because less new pavement is required.
- Decreased use of new pavements.
- Shorter construction time, resulting in reduced exposure of travelers and construction workers to work zone hazards.
- A better return on investment based on longer pavement service life.
- Reduced environmental footprint, based on decreased use of new materials.
In the Field
|Arizona||Implementation Assistance Program – The Arizona Department of Transportation is applying Pavement Renewal Solutions to renew pavement assets quickly and cost-effectively and to minimize the impacts on road users, to lower the costs of owning these assets, to decrease the use of new pavement, and to reduce the environmental footprint.||Lead Adopter||
Arizona Department of Transportation
|California||Implementation Assistance Program – The California Department of Transportation is implementing the use of rePave software to more accurately scope the pavement strategy most appropriate for the situation and existing conditions for a variety of projects. Training and webinars are critical to implementation.||Lead Adopter||
|Kentucky||Implementation Assistance Program – The Kentucky Transportation Cabinet is conducting training to identify and prove the effectiveness of at least one technique or process that could be implemented in a programmatic manner throughout the State. The goal is the development of an ongoing program that utilizes the identified technique or process.||Lead Adopter||
