ASTM D6690 - 21

ASTM D6690-21: The Definitive Standard for Joint and Crack Sealants

ASTM D6690-21 is the industry-leading standard specification for joint and crack sealants used in civil engineering applications. This comprehensive standard provides detailed requirements and test methods to ensure the performance and durability of sealants, helping construction professionals deliver high-quality, long-lasting infrastructure projects.

Ensure Compliance and Quality with ASTM D6690-21

Adhering to ASTM D6690-21 is crucial for civil engineering projects, as it establishes the essential criteria for sealant materials and installation. By specifying this standard, you can:• Verify that sealants meet stringent physical and chemical requirements for strength, flexibility, and weathering resistance.• Ensure sealants are compatible with the materials they will be applied to, preventing premature failure.• Confirm sealants can withstand the expected movement and environmental conditions of the application.• Maintain consistent quality and performance across all sealant products used in a project.

Comprehensive Specifications for Optimal Sealant Performance

ASTM D6690-21 covers a wide range of sealant types and applications, including:• Hot-applied sealants• Cold-applied, self-leveling sealants• Cold-applied, non-sag sealants• Sealants for use in portland cement concrete and asphalt pavements• Sealants for use in bridge and highway structuresThe standard outlines detailed requirements for sealant composition, physical properties, and testing procedures, ensuring sealants can withstand the rigors of civil engineering environments. Key specifications include:• Tensile adhesion and elongation properties• Resistance to hardening, cracking, and weathering• Compatibility with pavement materials• Resistance to flow and self-leveling characteristics• Ease of application and toolingBy adhering to ASTM D6690-21, construction professionals can have confidence that the sealants used in their projects will perform reliably and maintain their integrity over the long term.

Ensure Durable, Long-Lasting Infrastructure

Proper joint and crack sealing is essential for the structural integrity and longevity of civil engineering projects. ASTM D6690-21 provides the comprehensive guidance needed to select and apply sealants that can withstand the stresses and environmental factors inherent in infrastructure applications.Whether you're working on highways, bridges, pavements, or other critical civil engineering projects, specifying ASTM D6690-21 will help you:• Prevent water intrusion and damage to underlying structures• Reduce the risk of premature sealant failure and the need for costly repairs• Maintain a smooth, safe surface for vehicle and pedestrian traffic• Extend the overall lifespan of the infrastructureBy investing in high-quality sealants that meet the rigorous requirements of ASTM D6690-21, you can deliver durable, long-lasting civil engineering projects that serve the community for years to come.
