ASTM C1491
Full Name
ASTM C1491 – Standard Specification for Concrete Roof Pavers
Scope
ASTM C1491 covers the requirements for concrete roof pavers used as ballast and protection for roof membranes. The standard addresses various aspects to ensure the suitability and performance of concrete roof pavers in these applications.
The scope of ASTM C1491 includes:
- Material requirements:
- Specifies the use of hydraulic cement, water, and suitable mineral aggregates in manufacturing concrete roof pavers.
- Allows for incorporating other materials as specified by the purchaser.
- Physical requirements:
- Establishes minimum requirements for compressive strength and flexural load resistance.
- Addresses the ballast weight requirements, which should be specified separately.
- Recommends assessing freeze-thaw durability for pavers used in regions experiencing repeated freezing and thawing cycles under saturated conditions.
- Dimensional requirements:
- Specifies permissible variations in dimensions and weight of the pavers to ensure consistency and proper fit during installation.
- Specifies permissible variations in dimensions and weight of the pavers to ensure consistency and proper fit during installation.
- Sampling and testing:
- Outlines procedures for sampling and testing to verify compliance with the specified requirements.
- References other ASTM standards for testing methods to be used for various properties.
- Finish and appearance:
- Addresses surface finish and appearance requirements based on the purchaser’s specifications.
It is important to note that ASTM C1491 primarily focuses on the properties and testing of individual concrete roof pavers. It does not cover aspects like the design of roof ballast systems for wind uplift resistance, which should be addressed by consulting building codes and other relevant standards.
