About the research

The United States has approximately 600,000 bridges and 47,000 miles of interstate highways. More than 75% of bridges and 60% of highways are made of concrete. Concrete production consumes massive amounts of raw materials and energy, and US cement production emits about 67 million tons of carbon dioxide. A key to concrete decarbonization is using low-carbon cement. We propose to formulate, characterize, optimize, evaluate, and implement a new generation, low-carbon, energy-saving, and cost-effective cement made with calcined clay (CC)/natural pozzolan, Type I portland cement (I), and limestone powder (L), called CC·I·L cement. Implementation challenges will be addressed by (1) streamlining the testing process for characterizing raw materials and their blends, (2) using machine-learning techniques to optimize cement composition and predict performance, (3) developing prediction models for hydration and adiabatic temperature rise via software modification, and (4) conducting both laboratory and field investigations to comprehend performance. A roadmap will be developed defining goals, outcomes, and milestones for implementing CC·I·L in future transportation infrastructure.

About the research

This project is a task order under the main Federal Highway Administration (FHWA)-sponsored project, “Infrastructure Research and Technology Deployment Program.”

Past regional bridge load rating peer exchanges conducted by the FHWA from 2014 to 2019 proved effective to gain an understanding of the load rating practices used by state departments of transportation (DOTs). The exchanges helped make known the best practices and technologies being used for load rating bridges, posting bridges, and issuing permits. The success of these exchanges and the continual evolution of practices and technology coupled with newly imposed requirements provide reason for additional peer exchanges, which are intended to include representatives from all DOTs.

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:

  1. Develop and maintain a database of lead states approach, strategies, and strengths for Pavement Preservation “How” for the life of this task order;
  2. 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;
  3. 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;
  4. Review and update the current Pavement Preservation Checklist series;
  5. Develop a modernized version of the Pavement Preservation Checklist series to include a smart phone app; and
  6. Produce and embed brief videos demonstrating the key components of each checklist treatment.

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 FHWA’s transportation performance program and transportation asset management program represent major advancements for the stewardship of the nation’s highway system. The transportation asset management plans provide the first nationwide, consistent, and comprehensive summation of how state departments of transportation (DOTs) intend to manage the condition and performance of the National Highway System (NHS). Simultaneously, FHWA Transportation Performance Management (TPM) efforts have generated valuable performance measures and targets for safety, freight movement, traffic congestion, and the condition and performance of interstate and non-interstate NHS pavements and bridges.

This task order proposal allows for further advancement by providing additional guidance and training on how to better link asset management, transportation performance management, and performance-based planning and programming. To date, state DOTs may have developed their asset management plans in relative isolation from their long-range plans, in part because the development cycles for the two plans have not yet overlapped. Also, there has not been enough time for the gap analyses, risk assessments, or investment strategies to influence short-term transportation programs, which often are updated biennially.

This team will produce for the FHWA useful guidance documents and training that illustrate how performance-based planning and performance management enhance asset management. With this guidance and training, the potential of asset management, performance-based planning, and transportation performance management can be enhanced and be better aligned into a seamless way of doing business in DOTs.
