Aggregate sources: Aggregate can come from either natural or manufactured sources .Natural aggregate come from rock, of which there broad geological classifications. a. Igneous Rock: These rocks are primarily crystalline and are formed by the cooling of molten
be an indicator of asphalt absorption. A highly absorptive aggregate may lead to a low durability asphalt mix. In Portland Cement Concrete the specific gravity of the aggregate is used in calculating the percentage of voids and the solid volume of aggregates in computations of yield. The absorption
Gravel is made up of a variety of rock fragments that vary in size. Contrary to popular belief, gravel does not necessarily consist of tiny, powdery rock particles, but can range from granule to boulder in terms of size. Gravel is traditionally used to make roads, paths, and .

coarse aggregate and cured we then shape it back into a rock, but this time a shape that we want it to look like. We build highways, bridges, and structures. However this new rock, or concrete is heavy and is limited because of it's composition to protect from heat and cold. It protects us somewhat from the elements: rain, wind, and fire.

Clean or course aggregates consist of chips, 1" clean (#57), 2" clean, and 3" clean. Clean aggregates are typically used in the production of ready mix concrete or hot mix asphalt, chip and seal, pipe bedding, septic systems or to stabilize wet ground conditions. Smaller clean rock is .
Overview. The fine aggregate (mineral filler) is used to fill in the voids between the coarse particles, which increases the density of the asphalt concrete and provides load transfer between the larger particles. The asphalt binder is typically 56% of the mixture, and serves to bind the aggregates together.
