AASHTO T 219-87 (2018) provides a testing procedure to determine the chemical limits and particle size requirements of hydrated lime (specifically Type I and Type II) on a routine basis. This test aims to be reasonably accurate and quick, allowing for the assessment of lime quality in a timely manner.

It is important to note that this test procedure is based on hypothetical assumptions and focuses only on the principal constituents typically present in lime products. This simplification of the test procedure may result in a slight loss of accuracy. All test values are to be reported rounded off to the first decimal place.

While this test procedure is deemed adequate for routine quality control purposes, it is essential to acknowledge its limitations. A thorough understanding of the test's object and intent is necessary for proper evaluation, as it is just one approach to addressing the challenges of quality control for lime products.
