In the world of construction and landscaping, crushed stone materials are always in extremely high demand. Although there are different types of aggregate products available, crusher run remains one of the most frequently sought-after for a number of different applications.
On the other hand, crushed aggregates, defined as granular materials produced by human related activities such as blasting, crushing and so on, have rougher surface and more angular shapes comparing to natural sands. In that sense, the aggregates can be classified into two main categories: natural and crushed.

aggregate properties are considered in improved subgrade thickness determination. The results also indicate aggregates with certain properties are not appropriate for improved subgrade applications, even though they are not currently restricted by IDOT
Granular B Type I does not require crushing. Granular B Type II is crushed and hence may only be obtained from quarried rock, blast furnace slag, or nickel slag. Maximum size of Granular B Type II may be 150 106, or 75 mm. Granular B Type III is similar to Type I except it does not allow the use of uniform or poorly graded fine sands.
