AASHTO Guidelines

AASHTO Guidelines are a set of standards created by the American Association of State Highway and Transportation Officials to ensure the safety, durability, and efficiency of transportation infrastructure like roads, bridges, and highways. These guidelines provide best practices and technical specifications for designing, constructing, and maintaining transportation systems across the United States. They help engineers and planners create consistent, reliable, and safe infrastructure that meets national quality standards. Essentially, AASHTO Guidelines serve as a comprehensive reference to support effective transportation infrastructure development.
