ASTM C1645
Full Name
ASTM C1645 – Standard Test Method for Freeze-thaw and De-icing Salt Durability of Solid Concrete Interlocking Paving Units
Scope
ASTM C1645 outlines the standard test method for evaluating the resistance of solid concrete interlocking paving units to the effects of freezing and thawing cycles. The test involves subjecting the units to repeated cycles of freezing and thawing while immersed in either water or a 3% saline solution, depending on the intended use of the units in service.
The main objectives of ASTM C1645 are:
- To determine the effects of freezing and thawing on concrete paving units: the test assesses the durability of the units by measuring any deterioration, such as cracking, scaling, or loss of mass, that occurs during the freeze-thaw cycles.
- To evaluate the performance of paving units in different environments: the use of water or saline solution simulates the exposure conditions the units might encounter in real-world applications, allowing for an assessment of their suitability for different climates and de-icing practices.
- To provide a standardized test method: the standard ensures consistency and comparability of results across different laboratories and manufacturers, promoting fair evaluation and selection of concrete paving units.
However, ASTM C1645 does not:
- Provide a quantitative measure of service life: the test results do not directly predict the actual lifespan of the paving units in service, but they offer valuable insights into their relative durability under freeze-thaw conditions.
- Cover other aspects of paving unit performance: the standard focuses solely on freeze-thaw durability and does not address other factors like wear resistance, skid resistance, or structural performance.
Overall, ASTM C1645 serves as a valuable tool for assessing the freeze-thaw durability of concrete interlocking paving units, helping to ensure their long-term performance and suitability for various applications.
