Aggregates 101

regions of NW and NE PA, aggregate is often mined glacial till, or pit-run gravel. In general, limestone is the hardest of the rocks, with shale being the softest, while pit-run varies widely in its usefulness as a road aggregate. Gradation: Gradation is t he distribution of different sized stones comprising an aggregate by percent of weight.
