Aggregate stockpile sampling
Good practice for sampling aggregate applies to the sampling of RAP. Samples may be obtained during production or from a stockpile. Contractors should 17 May 2006 Sand Equivalent - If test fails on combined-stockpile aggregates, perform hot-bin or drum-mix-plant discharge sampling and testing prior to Stockpiling/Handling/Load-Out shale, sand particles, pyrite. These impurities affect the quality of the aggregates Samples. – Stockpile Load out Samples results representative of the mean concentration of soil stockpiles. Ó2004 Elsevier Ltd.

Their specification includes standard proce- dures for sampling aggregates from a roadway, flowing stream, conveyor belt, stockpile, or truck to ensure representative samples (North Dakota DOT 2015). sample of aggregate that is truly representative of the nature and condition of the aggregate in the stockpile, bin or transfer point is called aggregate sampling. ASTM D75 is the standard practice for sampling aggregates. The size of the sample obtained in the field is rather large to ensure that it is representative.

1 Oct 2019 Samples of aggregate for bituminous mixtures are submitted to the Engineer in accordance with the specifications for stockpiling material.
Account for Plant Breakdown. • Goal of mix design is to match plant production • Aggregate will breakdown tumbling through plant • Goal to return baghouse fines to mix. In perfect world would have storage silo and meter back into mix • Need to add baghouse fines to mix design to account for, typically 1.0 to 3.0%.

Aggregate Sampling from Stockpile Using a front end-loader, dig into the stockpile and set aside small pile of 10 to 15 ton of material. When forming the small pile, the loader bucket must be kept as low as possible and roll the material from the bucket rather than dumping the material. STOCKPILE SAMPLING Coarse Aggregate Stockpiles. Coarse aggregates are recommended to be sampled using the following procedure. 1) Locate the area of the stockpile from which hauling will begin. 2) Using a front-end loader, dig into the stockpile and set aside a small pile of 10 to 15 t of material. 1.1 This practice covers sampling of coarse and fine aggregates for the following purposes: 1.1.1 Preliminary investigation of the potential source of supply, 1.1.2 Control of the product at the source of supply, 1.1.3 Control of the operations at the site of use, and. 1.1.4 Acceptance or rejection of the materials.
