Strength characteristics of crushed gravel and limestone ...

As for the aggregate materials, crushed limestone and crushed gravel, commonly used in Illinois in base/subbase applications, were considered. Illinois dense graded base specifications allow aggregate materials with a maximum particle size of 25 mm for the CA 6 specification and 50 mm maximum particle size for the CA 2 aggregate.

The Effect of Stone Content, Size, and Shape on the ...

Three size gradations of limestone aggregate (#10–#4 sieve, #4–1/2 in., and 1/2 in–3/4 in.) were each admixed with dried clay in 10 percent by weight increments from 10–80 percent. Limestone aggregate, subrounded in an abrasion apparatus, was mixed with the same clay in similar proportions to study the effect of stone shape.
