Why is it important to keep the conditions of core storage cool?

Keeping the conditions of core storage cool is essential to preserve the core material and prevent degradation. When asphalt cores are stored in cooler environments, this helps to inhibit any chemical reactions that may lead to the breakdown of the asphalt binder and the aggregate within the core. Warm temperatures can accelerate oxidation and other degradation processes, potentially affecting the integrity and properties of the material.

Maintaining a controlled, cooler environment ensures that the cores remain representative of the in-place material, which is crucial for accurate testing and evaluation of the asphalt's performance. This is particularly important for quality control and assurance, as the results derived from these cores will inform decisions about the pavement's durability and longevity.
