Equipment to determine the soundness of coarse aggregate

3. Batch Soundness Loss of Coarse Aggregate. a. The “batch soundness loss” is the combined loss of each primary size of coarse aggregate being used in the mix. b. The “batch soundness loss” may be used only when the loss for one primary size exceeds the maximum allowable loss by not more than 2 %. c. Calculate the batch soundness loss using the weighted average basis shown
