Aggregate Selection

Interlocking Pavement

 We present different aggregates that can be used in an interlocking pavement installation.

We recommend a visual of lab testing of the aggregates you wish to use for a project.

Here are the aggregates that can be chosen for an interlocking pavement construction:

• Densely graded stone: ¾ inch angular stone, down the fines.

• Washed concrete sand: Coarse angular sand without fines. It has a good drainage ability.

Here is a cross section of an interlocking concrete pavement that illustrates every component of that system:

Permeable Pavement

Here are different aggregates that can be used in a permeable pavement installation.

The types of aggregates you should keep in mind for a permeable pavement are the following:

• Granite based hard stone. If you can’t find this type of stone, the aggregate you replace it with should be hardness tested.

• 2 to 3-inch clean stone for the subbase

• ¾ inch stone for the base

• #8 stone, ¼-inch clean stone. It is 2 inches thick and less than 5% passing a 200 sieve. It will act as a pre-filtration.

Here is a cross section of a permeable pavement, illustrating all its components in full infiltration conditions:

And partial infiltration conditions:
