Tests to Identify Poor Quality Coarse Limestone Aggregates

TxDOT specifications allow a coarse aggregate stockpile to have a five-cycle magnesium sulfate soundness (MSS) loss as high as 30 percent and still be acceptable. Hotmix asphalt concrete produced one day may have a MSS loss of 30 percent coarse aggregate and the next day may only have a MSS loss of 5 percent coarse aggregate.

Aggregate Moisture in Concrete Concrete Construction

May 31, 2013· In practice, aggregates in stockpiles, plants, and in the mixture are rarely, if ever, at these moisture conditions. The absorption of the aggregate indicates the quantity of water which will be absorbed into the pore structure. Most commonly, aggregates will have a moisture content that is either below or above this absorption limit.
