ASTM D6933-18 PDF Download

ASTM D6933-18 is a standard test method that determines the presence of oversized particles in emulsified asphalts through a sieve test. The retention of an excessive amount of particles on the sieve is an indication of potential problems in handling and application of the material. These particles can result from the agglomeration of the dispersed phase, as well as various factors such as storage, pumping, handling, temperature, and contamination from the tank, transport, or hose.

It is important to note that the accuracy and reliability of the test results are dependent on the competency of the personnel conducting the test and the calibration and maintenance of the equipment used. The standard does not guarantee reliable results solely based on compliance with Specification D3666. However, following the suggestions of Specification D3666 or similar guidelines can help evaluate and control some of the factors influencing the test results.
