ASTM D8140

ASTM D8140 is the ASTM standard guide for the use of foundry sand in asphalt mixtures, offering technical direction for considering this recycled material in pavement applications. It helps users understand how foundry sand may be incorporated into asphalt mixtures while keeping the focus on material suitability, performance considerations, and practical use. For agencies, suppliers, and mix designers, the standard supports more consistent evaluation and informed decision-making.

What is ASTM D8140?

This standard provides a guide for using foundry sand in asphalt mixtures, which makes it a practical reference for selecting and assessing this material in pavement-related work. ASTM D8140 does not read like a prescriptive product requirement; instead, it serves as a technical guide that can help users understand how foundry sand may fit into asphalt mixture design and related evaluation steps. As a result, it is useful for comparing material options and supporting controlled use.

Where is ASTM D8140 used?

ASTM D8140 is commonly used in asphalt mixture development, material sourcing, and quality-focused decision-making where foundry sand is being considered as an ingredient. It is relevant to organizations involved in paving materials, mix design review, and project specifications that address alternative or recycled materials. The standard may also be used by laboratories and technical teams that evaluate compatibility, consistency, and handling characteristics before the material is included in asphalt mixtures.

Why is ASTM D8140 important?

This guide matters because it helps bring consistency to the evaluation and use of foundry sand in asphalt mixtures. ASTM D8140 can support compliance efforts, procurement decisions, and quality control by giving stakeholders a shared technical reference. That reduces uncertainty when comparing sources or preparing mixture designs. For projects that use foundry sand, a recognized ASTM standard can also help manage risk and improve confidence in material selection and application.
