Nov 5, 2015 . Gradation and Loss by Wash of Aggregate.
The test can be run on either dry or washed aggregate. The washed sieve analysis takes longer but produces a more accurate gradation, particularly the percent passing the No. 200 (0.075 mm) sieve since the washing helps remove these small particles from the larger particles. The dry sieve analysis procedure is often.
AASHTO T 85 when used in Grading CW mixes. After drying in the plant, the aggregate retained on the 4.75 millimeter (No. 4) sieve shall have a loss of not more than 1.00 percent by weight when washed over a 2.36 millimeter (No. 8) sieve in accordance with the coating test in Subsection 407.03. (b) Fine Aggregate.

Nov 1, 2017 . All tabulations of these gradation data should clearly indicate whether washed or unwashed testing was used. 8-60.9.3 Procedure for Mixtures of Fine and Coarse Aggregates for Base Course. 1. The unwashed test sample must be thoroughly dried. Materials containing portions of reclaimed or recycled.
Use Part I to determine a weight-based, dry-sieve analysis for an aggregate sample. 1.3. Use Part II . a washed sieve analysis. 1.4. Use Part . used in the bituminous mixture being produced, then combine and sieve to yield the combined aggregate gradation. 3.7. Reverse Sections 3.2–3.6 when this proves more practical.

Sand Equivalent Test indicates relative proportions of undesirable clay-like fines in aggregates and granular soils. Test equipment is sold in complete kits or as individual components. Aggregate Washers prepare samples for gradation or measure fines content by washing away fines. They reduce labor cost and eliminate.

Asphalt aggregate gradation and size testing becomes much more efficient with an industrial scale. Discover how you can improve . How a Gradation Test Works. While the test can be run on either dry or washed aggregate, a washed sieve analysis is more accurate—even though it may take longer than a dry one.
Dec 1, 2014 . Aggregate is the main ingredient in Portland Cement Concrete and Asphalt Concrete. All aggregate used for construction purposes must be tested, physically and chemically, to verify its suitability for these uses. Every potential production site must be tested to ensure that the materials meet specifications.
