Exploratory Advanced Research Program (Brochure)
Publication No. FHWA-HRT-10-032
The Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU) established the Exploratory Advanced Research (EAR) Program with designated funding to conduct longer term, higher risk, breakthrough research with the potential for dramatic long-term improvements to transportation systems. This brochure provides an overview of the program, its primary focus areas, results, and how to become involved.
The EAR Program bridges basic research, such as academic work funded by National Science Foundation grants, and applied research, such as studies funded by State departments of transportation. The program strives to match opportunities from scientific discoveries with the needs of the highway industry.
The EAR Program also develops partnerships with the public and private sectors to apply ideas across traditional fields of research and stimulate new approaches to problem solving. Since its inception, the EAR Program has funded 25 projects, representing the investment of $22.6 million in FHWA funds and leveraging $12 million in matching funds.
Printed copies of the brochure are available from the PDC.
Nanoscale Approaches for Highway Research (Fact Sheet)
Publication No. FHWA-HRT-10-033
FHWA is working closely with government, industry, academic, and international partners to push forward a strategic investment in nanoscale research conducted in relation to highways. Nanoscale science, or nanotechnology, is the understanding and control of matter at dimensions between approximately 1 and 100 nanometers. This fact sheet discusses opportunities and challenges for nanoscale research in regard to highways, safety and system operations, environmental stewardship, and pavements.
In March 2009, FHWA's EAR Program held a workshop with experts from academia and other Federal programs to discuss nanoscale research and the role it can play in key highway research issues such as infrastructure, safety, operations, and environment. The workshop was a critical step in identifying opportunities for investment and assessing funding levels for nanoscale research that supports highway research needs. The workshop also provided the opportunity to inform the highway research community about nanoscale studies relevant to highways, inform nanoscale researchers about highway research needs, and identify potential opportunities for investing EAR Program funds within the nanoscale focus areas.

Integrity of Infrastructure Materials and Structures
Publication No. FHWA-HRT-09-044
Corrosion of bridges constitutes a major maintenance problem for the United States. Both steel and reinforced concrete structures face corrosion issues and require individual research and solutions. This report details current research and results for mitigating corrosion of bridges and structures.
For reinforced concrete bridges, recent research has focused on corrosion-resistant reinforcements. A component of this research addressed serviceability of 2304 stainless steel alloy (UNS S32304) as a cost-effective solid stainless steel grade that offers corrosion resistance comparable to more expensive solid stainless steel when used as reinforcement in concrete bridges. The research findings revealed no evidence of stress corrosion cracking and corrosion initiation occurring below 4.5 percent chloride solution under various conditions.
In the case of steel bridges, researchers developed an accelerated corrosion test for weathering steel with a range of exposure conditions that demonstrated sensitivity to chloride environments. The research findings confirm the field observations that indicate1 percent chloride is the maximum environmental exposure acceptable for unpainted structures fabricated from ordinary weathering steels.

Mapping the Future of Hydraulics Research: A Strategic Plan to Protect Highway Infrastructure (Fact Sheet)
Publication No. FHWA-HRT-10-034
As the Nation's highway infrastructure ages and the risk of bridge and culvert failures rises, the need to predict, detect, and prevent water-related damage grows more urgent. To stimulate advanced research in this area, FHWA's EAR Program convened the First International Hydraulics Research Forum in June 2007 to identify research priorities. This fact sheet highlights collaboration to develop a hydraulics research roadmap, ongoing cutting-edge hydraulics research, and efforts to develop a smart sensor network.
Forum discussion centered around three major areas of hydraulics research -- coastal, inland, and environmental -- and the need to establish communication, partnerships, and future direction. Two topics warranted special attention: advanced modeling capabilities such as physical, numerical, and supercomputing, and the implications of climate change for the field.
Forum participants also called for research into high-risk topics with long-term potential such as applications of smart materials (for example, integrated scour-monitoring systems). In addition, recommendations included developing hydrodynamic bridge pier and deck systems, and structures that can adapt to flow conditions using adaptive materials based on nanotechnology and biomimetic concepts.
