ASTM C1097 is the ASTM standard for hydrated lime intended for use in asphalt cement or bituminous paving mixtures. It provides a technical basis for identifying material suited to these paving applications, helping buyers, specifiers, and quality teams evaluate consistency and suitability. As a specification document, it supports clearer communication between suppliers and users and helps reduce uncertainty when hydrated lime is selected for asphalt-related work. ASTM C1097 is therefore a practical reference for procurement and compliance.

What is ASTM C1097?

ASTM C1097 is a standard specification focused on hydrated lime used in asphalt cement or bituminous paving mixtures. Its purpose is to define expectations for the material so it can be described, purchased, and checked against a recognized ASTM document. In practice, this type of specification helps align material requirements with paving applications where hydrated lime is part of the mixture design or production process. ASTM C1097 serves as a technical reference for consistent product evaluation.

Where is ASTM C1097 used?

This standard is commonly used in asphalt cement and bituminous paving mixture workflows, especially where hydrated lime is incorporated as part of material selection or mix preparation. It may be referenced by producers, suppliers, purchasers, and testing or quality control teams that need a clear basis for specifying the lime used in paving materials. ASTM C1097 is most relevant when hydrated lime must be matched to an established specification for roadway or paving-related applications.

Why is ASTM C1097 important?

ASTM C1097 matters because it helps bring consistency to the specification and acceptance of hydrated lime used in paving mixtures. A recognized standard can support better procurement decisions, clearer supplier requirements, and more reliable quality control. It also helps reduce ambiguity when comparing materials for asphalt cement or bituminous paving use. For organizations that rely on technical documents to manage compliance and performance expectations, ASTM C1097 provides an important common reference.
