The National Highway System

On December 9, 1993, at Union Station in Washington, D.C., U.S. DOT Secretary Federico Peña and FHWA Administrator Slater announced the submission of the National Highway System (NHS) plan to Congress. Peña also outlined his principles and goals for a National Transportation System (NTS).

Applied Research and Technology: New Guidelines for Accelerating the Use of Innovative Technology by the Highway Industry

by Richard A. McComb and Daniel F. Larson

The need to accelerate the integration of new technologies into the U.S. highway system has increased dramatically over the past decade as the Interstate Highway System has neared completion. Because Congress recognized the importance of technology application, it established the Applied Research and Technology (ART) Program.

Highway Innovative Technology Evaluation Center

by Louis Colucci and Robert Bryant

The Highway Innovative Technology Evaluation Center (HITEC), established in 1992 to serve as a nationally recognized service center and clearinghouse for evaluating innovative highway technologies, opened for business on January 4, 1994.

Modeling of Geotextiles and Other Membranes in the Prevention of Reflection Cracking in Asphaltic Resurfacing

by Luis F. DaSilva and Juan A. Confré

An analytic study on the use of membranes in asphaltic resurfacing of fractured pavements is presented in this article. Based on general laws such as Hooke's Law, Paris' Law, and the energy conservation law plus some reasonable hypotheses, the Fabric Effectiveness Factor (FEF) has been determined. This factor indicates the increment in the service life of an asphaltic overlay.

HYSIM: the Next Best Thing to Being on the Road<

by Elizabeth Alicandri

The Federal Highway Administration's (FHWA) Human Factors Laboratory has operated a Highway Driving Simulator (HYSIM) at the Turner-Fairbank Highway Research Center (TFHRC) since the early 1980s.

FHWA's Implementation Plan for SHRP Products

by Charles J. Churilla

Promising new equipment and improved materials, specifications, and tests are now becoming available as a result of the five-year Strategic Highway Research Program (SHRP). More than 100 new products and techniques were developed between 1987 and 1993 through the $150- million research program. SHRP research was targeted to improve highway technology in four specific areas: asphalt, concrete and structures, highway operations, and long-term pavement performance (LTPP).

Environmental Research: Helping Highways Improve the Quality of Life

by Ginny Finch

Over the past few years, technological advancements and protecting the environment have been catalysts for change in the policies and procedures of many federal agencies. "Environment" has become one of the most significant political buzzwords of the 1980s and 90s, but for the Federal Highway Administration (FHWA), environmental concerns are much more than a buzzword.

Looking for a Few Good IDEAs

by K. Thirumalai

The Innovations Deserving Exploratory Analysis (IDEA) Program of the National Research Council's (NRC) Transportation Research Board (TRB) is designed to nurture innovative concepts for technologies, systems, methods, and processes for application to highway and intermodal transportation practice.

The National Quality Initiative

by Donald Tuggle

Quality Management (QM) is a broad term for the overall process of ensuring quality products. Within the highway community, it encompasses such issues as contractor/consultant process control, owner acceptance issues, personnel qualifications and training, information management systems, performance-related specifications, innovative contracting practices to achieve quality, incentive/disincentive provisions, performance recognition, improved materials/tests/equipment, and quality improvement techniques.
