<div><a href="/blog/streamlining-aggregate-gradation-tests-tips-and-tricks"><img loading="lazy" src="/Content/Images/uploaded/blog/aggregates/streamline-aggregate-tests.jpg" alt="Streamlining Aggregate Gradation Tests: Tips & Tricks" style="display: block; margin-left: auto; margin-right: auto; width: 100%; max-width: 715px;" /> </a></div><p>Sieving for particle size distribution is the primary test requested for construction aggregate samples. Whether field samples are being tested to evaluate a new aggregate source or just coming in as part of day-to-day quality control of production, particle size distribution is a primary consideration. If processing and sieving is not handled efficiently, it creates a backlog.</p>
