ASTM C1097 - 13

Overview

ASTM C1097 - 13 is the standard specification for hydrated lime intended for use in asphalt cement or bituminous paving mixtures. This standard outlines the requirements and testing methods necessary to ensure the quality and performance of hydrated lime in construction applications. Hydrated lime plays a critical role in enhancing the properties of asphalt mixtures, contributing to improved durability, workability, and adhesion.

Key Requirements

The standard specifies several key requirements for hydrated lime, including:

• Physical Properties: The hydrated lime must meet specific criteria regarding fineness, moisture content, and reactivity to ensure optimal performance in asphalt applications.
• Chemical Composition: The lime must contain a minimum percentage of calcium hydroxide and meet limits on impurities to maintain the integrity of the asphalt mixture.
• Testing Methods: ASTM C1097 - 13 outlines the procedures for testing hydrated lime, including methods for determining its physical and chemical properties.

Implementation Benefits

Utilising ASTM C1097 - 13 compliant hydrated lime in asphalt mixtures offers several practical benefits:

• Enhanced Performance: Hydrated lime improves the adhesion between asphalt and aggregates, reducing stripping and increasing the longevity of the pavement.
• Improved Workability: The addition of hydrated lime can enhance the workability of asphalt mixtures, making them easier to handle and apply during construction.
• Environmental Considerations: Using hydrated lime can contribute to more sustainable construction practices by improving the lifespan of pavements and reducing the need for repairs.

Compliance Value

Adhering to ASTM C1097 - 13 is crucial for compliance professionals in the construction industry. Compliance with this standard ensures that:

• Quality Assurance: By following the specifications outlined in ASTM C1097 - 13, companies can guarantee the quality of their materials, leading to safer and more reliable construction outcomes.
• Regulatory Compliance: Many jurisdictions require adherence to recognised standards like ASTM C1097 - 13 for materials used in public works and infrastructure projects, ensuring compliance with local regulations.
• Market Competitiveness: Companies that utilise compliant materials can enhance their reputation and competitiveness in the market, as clients increasingly demand adherence to recognised standards.

In conclusion, ASTM C1097 - 13 provides essential guidelines for the use of hydrated lime in asphalt mixtures. By ensuring compliance with this standard, construction professionals can enhance the quality and performance of their paving materials, ultimately leading to more durable and sustainable infrastructure.
