Learning Objectives:

• Identify common standard specifications used in civil engineering projects, including those developed by organizations such as ASTM, ACI, and AASHTO.
• Understand the structure and content of standard specifications, including material requirements, testing procedures, and acceptance criteria.

---

Test methods are standardized procedures used to assess the properties, performance, and quality of construction materials and products. They provide objective criteria for evaluating materials and determining their suitability for specific applications.

Standard specifications establish requirements and criteria for materials, products, and construction practices. They define the minimum acceptable standards that must be met for compliance with project specifications and regulatory requirements. Standard specifications are typically developed by industry organizations, government agencies, and professional societies, such as the American Society for Testing and Materials (ASTM), American Concrete Institute (ACI), and American Association of State Highway and Transportation Officials (AASHTO).
