Standards, test methods, specifications and acceptance criteria
AASHTO Standards
The American Association of State Highway and Transportation Officials (AASHTO) is a standards-setting organization that develops and publishes standards for transportation infrastructure. These standards cover a wide range of materials, construction practices, and testing methods used in the construction and maintenance of highways, bridges, and other transportation facilities.
AASHTO standards play a crucial role in ensuring the quality, safety, and durability of construction materials and projects. By adhering to these standards, construction professionals can:
- Improve project quality: AASHTO standards provide clear guidelines for material specifications, testing procedures, and construction practices, helping to ensure optimal project quality.
- Enhance safety: AASHTO standards help to identify potential hazards and risks associated with construction materials and practices, allowing for proactive measures to be taken to protect workers and the public.
- Reduce costs: by promoting consistency and efficiency in construction practices, AASHTO standards can help to reduce project costs and minimize rework.
- Facilitate regulatory compliance: AASHTO standards are often referenced in federal, state, and local regulations, making them essential for compliance with building codes and other legal requirements.
