Preserving the Nation’s Roadways

This comprehensive report explores effective techniques and materials for managing national roadways while addressing the critical funding gaps faced by the U.S. transportation system. Highlighting historical legislation from the 1887 Act to the Interstate Highway System, it provides insight into current practices as documented by the ASCE 2009 Infrastructure Report Card. With over 47,000 miles classified as "poor" or "mediocre," this study evaluates innovative program delivery, user-paying systems, and recommendations for improving roadway maintenance and construction in collaboration with both public and private sectors.
