About This Item
ASTM D140/D140M is the ASTM standard for sampling asphalt materials, providing a practical framework for obtaining representative samples for testing and quality assessment. As a standard practice, it helps support consistent sample collection so results can better reflect the material being evaluated. This matters in procurement, inspection, and laboratory workflows where reliable sampling is essential to meaningful comparisons, compliance checks, and product performance decisions.
Overview of ASTM D140/D140M
Standard Practice for Sampling Asphalt Materials outlines a recognized approach for collecting asphalt material samples in a manner suitable for subsequent examination and testing. The designation ASTM D140/D140M identifies the inch-pound and SI versions of the practice, making it useful across different measurement systems. In technical and quality control settings, the document is commonly used to support uniform sampling procedures and reduce variation introduced before testing begins. ASTM D140/D140M is therefore a key reference for consistent material handling.
Common use cases of ASTM D140/D140M
This standard is commonly used when asphalt materials must be sampled for laboratory evaluation, acceptance checks, or routine quality control. It is relevant to workflows involving asphalt shipments, storage containers, or other material forms where a representative sample is needed for testing. ASTM D140/D140M may also be referenced by contractors, producers, inspectors, and testing labs that need a consistent sampling practice before performing material analysis or documenting compliance-related results.
Benefits of using ASTM D140/D140M
Using ASTM D140/D140M helps improve consistency in how asphalt samples are obtained, which can support more dependable test results and reduce uncertainty in material assessment. It also provides a common technical reference for buyers, suppliers, and laboratories, helping align sampling methods across different teams and projects. For organizations focused on quality control and compliance, the standard can reduce avoidable variation, support better procurement decisions, and strengthen confidence in downstream testing outcomes.
