What is the frequency of performing a gradation test of fine/course aggregates?

The frequency of performing a gradation test on fine and coarse aggregates is crucial for assessing the quality and performance of the materials used in construction, particularly in asphalt mixtures. Conducting this test once a day ensures that any variations in aggregate size distribution are detected promptly. This regular testing helps in maintaining desired specifications and ensures that the materials are consistent and suitable for the intended application. By monitoring the gradation daily, you can make timely adjustments to the processes or materials used, which is essential for achieving optimal performance in paving applications.

Daily testing allows for a proactive approach to quality control, identifying potential issues before they affect the final product. Consistent gradation contributes to the stability, workability, and overall durability of asphalt mixtures, making frequent testing a best practice in quality assurance during the asphalting process.
