AASHTO #57 Crushed Stone


AASHTO #57 Aggregate

 

AASHTO #57 aggregate is a crushed stone grade that is gravel-like and made from a blend of stones five, six and seven. It comes from natural rock, so the pieces are jagged and angular.

 

 

What Is #57 Crushed Stone?AASHTO #57 Washed aggregate stone type

 

AASHTO #57 consists of many common kinds of rocks, including quartzite, washed gravel, granite, argillite, limestone and traprock. At Union Quarries, we exclusively mine limestone for our #57 stone size as well as our other aggregate options.

 

It has remained a popular aggregate choice in agriculture, landscaping and construction. The main benefit is that it is large enough to use in rugged applications, and these stones tend to be more porous, so they allow for drainage.

 

AASHTO #57 will not compact, yet with vibratory compacting equipment, it will have slight vertical compaction that’s necessary for certain applications. When buried, there are enough gaps between and within the stones that air and water can pass through, keeping trees, other vegetation and groundwater healthy. This drainage also prevents pooling and flooding.

Stones in AASHTO #57 blend are detected with a 1.5-inch sieve, which is why the #57 stone size is around 1 to 1.5 inches. Its size makes it useful for weight-bearing applications such as foundation beds and driveways.
