About the research
The Process Document was developed to help agencies manage and evaluate work zone activities and document the lessons learned. Its objective is to outline a structured post-construction evaluation process that uses a feedback loop to help evaluate and improve performance during the construction phase and generate lessons learned for future use.
The scope for the work was as follows:
- Define a structured review process that includes evaluation
- Define a feedback loop to document and mitigate project issues and generate lessons learned
- Develop a structure for lessons learned documentation
- Demonstrate the implementation of lessons learned in example projects
The four appendices (A through D) at the end of the Process Document were designed to be easily accessed at a later date. Appendix C provides a sample Lessons Learned form that readers can adapt and use on their projects.
The Discussion Facilitation Guide is a companion document to the Process Document, and the purpose is to provide resources to facilitate discussion during training. This document provides a training discussion outline with recommended steps for facilitation. Everything mentioned in this companion document is a suggestion and can be adjusted accordingly.

About the research
This project is a task order under the main Federal Highway Administration (FHWA)-sponsored project, “Infrastructure Research and Technology Deployment Program.”
The Utah Department of Transportation (UDOT) coined the phrase, “good roads cost less.” UDOT emphasized the long-term financial savings that agencies gain when they keep roads in good condition through timely preservation and maintenance.
The Center for Transportation Research and Education (CTRE) team proposes to demonstrate the effects of bridge and pavement conditions on a wide array of system performance objectives. The team will demonstrate how state departments of transportation (DOTs) can, in their transportation asset management plans (TAMPs), enhance performance in all areas by sustaining a state-of-good-repair (SOGR) for National Highway System (NHS) pavements and bridges. The CTRE approach also will show how a TAMP can communicate to stakeholders the linkages between the SOGR and achievement of system performance goals.

About the research
This project is a task order under the main Federal Highway Administration (FHWA)-sponsored project, “Technical and Support Services for the FHWA Construction Management Team.”
Whether a highway pavement is constructed using concrete or asphalt, the structure will deteriorate over time because of traffic loading and environmental factors. Technologies such as thin overlays, micro surfacing, slurry seals, and chips seals are some pavement preservation treatments applied to asphalt pavements. Technologies such as full depth patching, partial depth patching, dowel bar retrofitting/ cross-stitching, and diamond grinding are some pavement preservation treatments applied to concrete pavements. These treatments can be very effective in extending the performance life of pavements if applied at the right time on the right project with quality construction and materials.
The Every Day Counts Four (EDC-4) Pavement Preservation “How” initiative accelerates the national deployment of underutilized proven technologies and techniques to construct quality pavement preservation treatments with quality materials. This includes the use of sustainable quality materials and methods, construction equipment, and assuring a quality workforce to construct these surface treatments.
The objective of this task order is to assist in the peer-to-peer exchange of lead state and exploring state, to exchange knowledge about how to effectively implement Pavement Preservation “How”. The focus of the exchange will be based upon the concepts, capabilities, and applications of constructing pavement preservation treatments with quality materials for transportation agencies, contractors, consultants, and FHWA staff.
The objectives of the task order are:
- Develop and maintain a database of lead states approach, strategies, and strengths for Pavement Preservation “How” for the life of this task order;
- Identify the needs and desires of exploring states to learn how to implement Pavement Preservation “How”. Align the exploring agency needs with a lead agency strength. Organize, facilitate, and accompany a peer-to-peer exchange between the two agencies;
- Develop tech briefs for each peer-to-peer exchange that contain example guiding documents, specifications, work flows, and lessons learned to help other states adopt quality construction and materials for pavement preservation;
- Review and update the current Pavement Preservation Checklist series;
- Develop a modernized version of the Pavement Preservation Checklist series to include a smart phone app; and
- Produce and embed brief videos demonstrating the key components of each checklist treatment.

This Guide provides bridge engineers and owners with general information and typical details to help standardize orthotropic steel deck (OSD) bridge design/fabrication to make it more competitive. This document does not intend to set a national standard but to help inform the effort through reduced parametric variations.
OSD bridges can be either closed- or open-rib systems, and this Guide begins with background information regarding OSD bridge design.
General considerations with respect to OSD bridges are discussed, followed by specific instructions for closed- and open-rib systems including rib geometry, size, and fabrication methods. Suggestions for deck plate selection are provided followed by a discussion of wearing surface types and selection considerations. Lastly, suggestions for floorbeam/diaphragm design are provided.
Throughout the document, short summaries on the performance of several in-service OSD bridges are provided.

About the research
This project describes a methodology to evaluate the benefits and costs of objectives- and performance-based traffic signal operations and maintenance. The methodology includes a quantitative component supported by a subjective analysis. The intent of the methodology is to describe advantages and disadvantages of using a performance-based traffic signal monitoring process, executed through the automated traffic signal performance measures (ATSPM), when compared to the traditional approaches of monitoring and retiming traffic signals. The methodology is intended to validate the attainment of traffic signal program objectives and agency goals as articulated in a Traffic Signal Management Plan, Transportation System Management and Operations Plan, or other strategic planning document(s).
