What procedure is followed when performing the wash test?

The correct procedure for performing the wash test is ITP11. This test is crucial for determining the amount of fine material, such as clay and silt, present in aggregates. The wash test involves washing a sample of aggregate with water to remove these finer particles, which can affect the performance of materials in construction applications.

ITP11 provides detailed instructions on how to properly conduct the wash test, including the necessary equipment, sample preparation, and steps for obtaining accurate results. Understanding and following ITP11 ensures consistency in testing and reliable results that can inform aggregate quality assessments.

In this context, the other procedures listed, ITP10, ITP12, and ITP13, focus on different tests or aspects of aggregate evaluation and would not be appropriate for the specific process of conducting the wash test. This highlights the importance of knowing the correct procedures associated with standard testing methods in aggregate technology.
