The United States has one of the most extensive transportation systems in the world, representing trillions of dollars of public and private investment. To fulfill its role as the guardian of this critical highway infrastructure, FHWA is engaged in forward-looking research that supports safety and environmental sustainability while modernizing bridges and roads through better materials, new construction techniques, and consistent quality control. This research increases the highway system's productivity and performance, reduces operational and replacement costs, and ensures a world-class highway system long into the future.
The strength of the infrastructure in the United States depends on quality materials, sound construction techniques, and reliable maintenance practices. Infrastructure research explores emerging technologies that will improve the safety and reliability, structural integrity, and longevity of the Nation's bridges and roadways. A strong infrastructure must also be sustainable and environmentally sound. New pavement materials will have fewer impacts on air quality and ambient noise levels.
Consistent quality assurance methods developed through FHWA research are enhancing design, materials testing, construction, and inspection procedures for roads and bridges. These methods improve how programs are delivered.
