AASHTO #67 Crushed Stone

The American Association of State Highway and Transportation Officials (AASHTO) defines the sizes of crushed stones. AASHTO #67 crushed stone is used mostly on construction and landscape projects as an aggregate, decoration or in a mix for concrete.

What Is #67 Crushed Stone?

AASHTO #67 stone is similar to 2B stone in size. In some applications, #67 gravel might be used with other stone types, such as sand or other smaller aggregates to achieve the desired compaction and drainage. The material is produced by breaking rocks down into varying sizes, #67 being just one of them.

The process involves mining suitable rock deposits and then crushing them down into different-sized products, which are all used for different applications. Crushed rock is often made from different rock types, including limestone, granite and trap rock, depending on where it is quarried. The stone’s angular shape and rough texture help it lock together for foundations but still allow water to drain through.

The advantages of crushed stone include:

  • Durability: Crushed stone is a natural, durable material, making it ideal for high-traffic areas.
  • Versatility: You can use AASHTO #67 for a multitude of applications in construction and landscaping. The use will vary depending on the dimensions of the stone.
  • Drainage: Crushed stone allows for easy draining of water and moisture. This makes it ideal for layering and using it for foundations.


AASHTO #67 Stone Size

The stone can be as small as ¼ inch with a 1-inch topsize. The material is well-graded, which means it includes a mix of stone sizes within the specific range. The variety of #67 stone allows for it to compact well and give a stable base while also providing good drainage capabilities.


AASHTO #67 Uses

AASHTO #67 is commonly used in a premix for ready-mixed concrete. But you often find it used in other ways, mostly in drainage, foundation, as a road base and as an asphalt aggregate. Other uses include:

  • Backfilling for retaining walls
  • Foundation drains
  • Septic fields
  • Base layers for roads
  • Decorative uses
  • Flower beds and walkways
  • Railroad ballast overlayer

AASHTO #67 stone is also used as a foundation material for construction projects in residential, commercial buildings and other structures. Because it compacts well, AASHTO #67 gravel can be used under concrete slabs and sidewalks or as a utility pipe bedding.
