Full title and description
ASTM D3666-26 — Standard Specification for Minimum Requirements for Agencies Testing and Inspecting Road and Paving Materials. This specification sets minimum personnel, facility, quality-system, and competency criteria used to evaluate and accredit agencies that perform testing and inspection of road and paving materials (including bituminous paving materials).
Abstract
This standard defines baseline requirements for field and laboratory personnel, quality management systems, and organizational capability for agencies engaged in testing and inspection of road and paving materials. It provides criteria for evaluating an agency’s technical competence to perform designated tests, and it is intended to be used as a basis for qualifying or accrediting public and private testing and inspection agencies.
General information

Scope
This specification covers minimum requirements for both field and laboratory personnel, requirements for establishing and maintaining a quality management system, and minimum qualifications for agencies engaged in testing and inspecting road and paving materials. It supplies criteria to evaluate an agency’s ability to perform designated tests and to establish guidelines for organization, personnel, facilities, and quality systems; it may be supplemented by project-specific or complementary criteria (for example, ASTM E329).
Key topics and requirements
- Minimum personnel qualifications and training requirements for field and laboratory staff.
- Requirements for a documented quality management system and associated records.
- Facility, equipment, and calibration requirements to ensure valid test results.
- Criteria and procedures for evaluating agency capability and scope of accreditation.
- Guidance on test-method competence, reporting, and data integrity for road and paving materials.
- References to complementary standards and accreditation practices (e.g., ASTM E329, internationally recognized laboratory competence frameworks).
Typical use and users
Used by state and local Departments of Transportation (DOTs), municipal public-works agencies, private testing laboratories, construction and paving contractors, owners’ representatives, and accreditation bodies to establish or assess the minimum qualifying criteria for agencies that test and inspect road and paving materials. It is commonly applied when pre-qualifying laboratories and inspection agencies for project bidding, contract compliance, or regulatory acceptance.
Related standards
ASTM E329 (Criteria for Inspection Agencies and Testing Laboratories) is explicitly cited as a complementary document in the scope and guidance of D3666. In practice, agencies qualifying under D3666 also align with international laboratory competence and accreditation frameworks such as ISO/IEC 17025 (general requirements for the competence of testing and calibration laboratories) and, where relevant, ISO 9001 for management-system alignment.
