TOTAL MOISTURE CONTENT OF AGGREGATE BY DRYING AASHTO

The moisture content in aggregate is used to determine the binder content for HMA during production of the mixture in a plant. The procedure requires that a known amount of aggregate be obtained, the aggregate heated to remove the moisture, and the percentage of moisture determined. Ovens, hot plates, heat lamps or microwave ovens are used for heating the sample.

Determining Moisture in Aggregate for Mix Proportioning

01/03/1986· For making batch calculations it is handiest if moisture has been calculated as percent of the SSD weight of the aggregate. The total moisture measured in the test represents both the free moisture and the moisture that the aggregate absorbs. Only the free moisture becomes part of the mix water. The absorbed water, usually about 1 percent, remains within the aggregate. If the coarse aggregate

Aggregate Moisture Content| Concrete Construction

16/12/2010· A: The term is one of four used to describe the moisture content of the aggregate prior to mixing, and refers to a condition where all pores in each particle of aggregate are filled with water, but no excess water appears on the surface of the particle. The other terms are “ovendry” for aggregate that contains no moisture, “air dry” for aggregate that has absorbed some moisture but less than its potential absorption, and “wet” for aggregate

HOW THE MOISTURE CONTENT AND WATER

The aggregate absorbs water in concrete and thus affects the workability and final volume of concrete. The rate and amount of absorption within a time interval equal to the final set of the cement will only be a significant factor rather than the 24 hours absorption of the aggregate. It may be more realistic to consider that absorption capacity of the aggregates which is going to be still less

Moisture Content Pennsylvania State University

The moisture content of aggregates in the field is much closer to the SSD state than the OD state. The bulk specific gravity (BSG) of aggregates is more accurately determined by the displacement method in the SSD condition. The moisture content can be calculated directly from measurements of (BSG) using the displacement method.

Measuring moisture content: It’s more complicated than

Unfortunately, moisture content is often reported only as a percentage, without any indication of which method was used. Though it is easy to convert between wet and dry basis, confusion and potential problems occur when comparisons are made between moisture contents reported on a different basis. In addition, moisture content reported on a dry basis can actually result in a percentage value
