Aggregate - Pavement Interactive

Aggregate " is a collective term for the mineral materials such as sand, gravel and crushed stone that are used with a binding medium (such as water, bitumen, portland cement, lime, etc.) to form compound materials (such as asphalt concrete and portland cement concrete). By volume, aggregate generally accounts for 92 to 96 percent of HMA and about 70 to 80 percent of portland cement concrete.

The Effect of Aggregate Properties on Concrete

The moisture content of an aggregate is an important factor when developing the proper water/cementitious material ratio. All aggregates contain some moisture based on the porosity of the particles and the moisture condition of the storage area. The moisture content can range from less than one percent in gravel to up to 40 percent in very porous sandstone and expanded shale. Aggregate .

Aggregate Test - Northstone Materials

Polished stone value (PSV) - This is a most important test that an aggregate can undergo if it is to be used as a road surface course. If an aggregate polishes too much under the polishing effect of vehicle tyres, the road surface becomes very slippery, especially when wet, and the number of skidding accidents can increase. For the test, 10 mm chippings are placed face-down in a curved ...

- Aggregate Moisture and Making Adjustments to Concrete

The moisture content of an aggregate when batched in concrete mixtures is an important consideration. Aggregate particles have internal pores that absorb water. Aggregate stored in a stockpile or bin is typically in a wet condition, meaning it contains absorbed water and moisture coating the surface, called free or surface moisture. The total moisture content of an aggregate sample is the sum ...
