Aggregate Packing

Aggregate packing concepts developed in the field of high-performance cement concrete, were transposed to the field of asphalt concrete. These concepts, associated with the use of the gyratory compactor on aggregates only, enabled the development of a new laboratory design procedure of dense high-modulus asphalt concretes (HiMAs).

The Complete Guide to Crushed Stone and Gravel

 · Crushed stone: If you hear the generic "crushed stone" term, it usually refers to stone that has a mixture of stone dust in it. This type of stone is best used for a base when heavy compaction is needed. As a result, it is typically used for the base of concrete and paving projects, foundations of structures, and driveway bases.

Tips to maximize crushing efficiency

 · Efficiency can be defined by the ratio of a machine''s work to the energy supplied to the machine. To apply what this means to your crusher, operations produce the exact sizes in the reduction process that their market demands. In the past, quarries produced a range of single-size aggregate products – up to 40 mm in size.

How much volume is lost after compacting 3/4" crushed stone?

The loose drop weight of a relatively uniform (all the rocks are similar size and shape) 3/4" stone will be about 80-90% depending on the stone (angularity and phi). Presuming that you are compacting to of some form of "proctor density", because you''re awesome at compacting and have a monster machine (and thin lifts), that''s 100/80=125%.

Notice that in the passive case, if the wall is pushing into clean crushed stone, the K p value is 5.8; however, we allow K p = 3 to be used when Expanded Polystyrene Foam (EPS) is present to cushion the movement. This value can be further reduced as follows: K p (mobilized) = (Thermal Movement/(0.05 * Wall Height)) * K p; Provided K p >= 0.5 The minimum value of K p (mobilized) that we allow ...

Aggregates for Concrete

Crushed stone is produced by crushing quarry rock, boul-ders, cobbles, or large-size gravel. Crushed air-cooled blast-furnace slag is also used as fine or coarse aggregate. The aggregates are usually washed and graded at the pit or plant. Some variation in the type, quality, cleanli-ness, grading, moisture content, and other properties is expected.
