P amp Q University Lesson 9 Washing amp Classifying Pit amp Quarry

Sep 10, 2015018332Washing and classifying of aggregate can be considered in two parts, depending on the size range of material. Coarse material Generally above 38 in. sometimes split at 14 in. or 4 mesh. In the washing process it usually is desired to remove foreign, objectionable material, including fine particles. Fine aggregate From 38 in. and smaller.

Aggregate

An aggregates particle size distribution, or gradation, is one of its most influential characteristics. In HMA, gradation helps determine almost every important property including stiffness, stability , durability , permeability, workability , fatigue resistance , frictional resistance and resistance to moisture damage Roberts et al., 1996.
