FHWA Resource Center

Technology Deployment

Technologies & Innovations By Department


Market-Ready Technologies
The FHWA, in conjunction with the American Association of State Highway and Transportation Officials (AASHTO), has selected "market-ready" technologies and innovations that warrant special focus and deployment within the transportation sector. Information about each of these hot technologies is provided.

Additional Technology and Innovations
The Resource Center's Technical Service Teams are currently working to deploy these market-ready technologies and innovations in their respective areas. In addition, each of the teams is deploying additional technologies and innovations, specific to their respective specialty areas. Information on these technologies is also provided, along with the names of individual team members who can be contacted for further details.

The FHWA top market-ready technologies and the priority technologies and innovations that the Resource Center teams are also promoting are not all-inclusive. Rather, these technologies and innovations are those considered ready for deployment. In addition to this effort, the Resource Center Technical Service Teams are also collecting, documenting and sharing information on innovative concepts and practices. Information on these best practices and success stories is available from each of the teams.

The technologies and innovations (T&Is) described below are those that the Federal Highway Administration (FHWA) believes warrant special attention. Candidates for this list were evaluated against criteria that included:

  • Do they, particularly the "vital few," which are marked with an asterisk (), support agency priorities, including strategic goals?
  • Is there a user need and likelihood of implementation?
  • Are they developed to the point of being truly market-ready, with a tool(s) available for the field to market?
  • Is expertise available to support deployment and implementation?

Brief statements for each T&I provide additional information in the form of an evaluation checklist.

This list is not intended to include all T&Is available. Numerous T&Is are being developed, but are not yet ready to be marketed in the field. In addition, many T&Is are considered good concepts, practices, and/or success stories that should continue to be shared. This initial list is intended to be a living list: A process will be developed for reviewing and updating these T&Is.

Contact: David Winter, 202-366-4631.

Geotech & Hydraulics

Augered Cast in Place (ACIP) and Continuous Flight Auger (CFA) Pile Foundations - This technology is characterized by the drilling of a hollow-stem auger into the ground, forming the diameter of the pile. Sand-cement grout or concrete is pumped into the hole as the auger is being withdrawn from the hole, eliminating the need for temporary casing. After the auger is removed, reinforcement is installed in the pile. For certain applications, these foundation systems can be constructed faster and more economically than other deep foundation alternatives such as driven piles or drilled shafts.

Pavement and Materials

Warm Mix Asphalt (WMA) is the generic term for a variety of technologies that allow producers of Hot Mix Asphalt (HMA) pavement material to lower temperatures at which the material is mixed and placed on the road. It is a proven a technology that can:

  • Reduce paving costs.
  • Extend the paving season.
  • Improve asphalt compaction.
  • Allow asphalt mix to be hauled longer distances.
  • Improve working conditions by reducing exposure to fuel emissions, fumes, and odors.

Safety EdgeSM - Pavement edge drop-off on highways has been linked to many serious crashes, including fatal collisions. To mitigate vertical drop-offs, FHWA advocates installing the Safety EdgeSM on pavements during paving or resurfacing projects. This technology allows drivers who drift off highways to return to the pavement safely.

Roadway departures account for over half of all fatal crashes. Not all of these crashes involve speeders and drunk drivers. Some could have been easily prevented if a vertical pavement edge drop-off had not been present.

Many of these tragedies might have been prevented by a cutting-edge technology known as the Safety Edge SM. This simple, inexpensive solution is a focus of the FHWA's Every Day Counts program.

Intelligent compaction (IC) rollers greatly improve the quality, uniformity and long-lasting performance of pavements today. Using vibration and a system to collect, process, and analyze the measurements in real time, IC rollers are able to compact greater amounts of pavement with fewer passes than the traditional static rollers sometimes in a much shorter time. IC efficiencies produce time, cost and fuel savings. With more efficient paving processes, production can increase and State Departments of Transportation (DOTs) can construct greater amounts of roadway daily.

High Friction Surface Treatments Maintaining the appropriate amount of pavement friction is critical for safe driving. In locations where drivers may brake excessively; for example, when going around curves, down hills or steep grades, or when approaching an intersection; the road surface can become prematurely polished, reducing the pavement friction and allowing vehicles to skid when the drivers brake. Drivers may also be speeding or distracted, contributing to the high-crash rates in critical locations. Wet road surfaces can also reduce pavement friction and cause skidding or hydroplaning.

Several high friction surface treatment products are available now and other, more cost-effective products are being developed. The HFS products use aggregates that are both polish- and wear-resistant and develop channels to prevent water buildup on wet surfaces. The bonding materials such as Epoxy and other available blends are designed to set quickly. HFS treatments can be applied by machine at a similar speed to other paving surface treatments, or applied with hand tools, but the road surface must be durable with few to no cracks and crumbling.

Highway Economic Requirements System, State Version (HERS-ST) - In the past, transportation agencies have had to rely on engineering applications for long-range planning and programming. However, many agencies are beginning to focus on system performance rather than simply on dollars spent or miles improved. This Transportation Asset Management approach has created a demand for planning tools that incorporate economic factors, especially user benefits and costs, in addition to traditional engineering considerations. Because existing engineering software packages were not designed specifically for managing transportation assets, they did not adequately address these agencies' changing needs. To address this problem, the Federal Highway Administration (FHWA) developed the Highway Economic Requirements System, State Version (HERS-ST) from the national-level HERS program that FHWA has used since the early 1990s.
