tion or gradation within a given aggregate size. With aggregate size number 6 of rounded stones, for example, 20–55 percent of the sample (measured by weight) should pass through a 1/2inch sieve. And, with aggregate size number 7 of crushed stones, 0–15 percent of the sample (measured by weight) should pass through a No. 4 sieve.
1. The listed AASHTO designations are for gradations only. The stone must also be clean, crushed, angular. For example, a specification for #4 stone would state: "Clean, crushed, angular No. 4 .

#67 Gravel is a crushed bluegray granite that is dryscreened to measure roughly 3/4″, meaning the actual size of any particular piece will be from 1/2″ to 1″ long. Stone dust and pea gravel are screened out, giving you an attractive landscaping material with superb drainage qualities.

Size 1/41/2 used mainly for the base, the first layer before pavers s and or as great also for pathways. can use as top layer for driveways if having smaller compact vehicles, a little easier to walk on too.
Aggregates Base (DenseGraded Base Coarse) Aggregate base course is an engineered mixture of coarse and fine aggregate designed to support heavy loads and is used in many applications such as foundations for highways and buildings as well as support of equipment on unpaved surfaces such as job site roads and oil well pads.
STONE #1. 3⁄4″ X 3⁄16". Washed 1 Stone is a very clean, washed clear gravel graded from 3/16″ to 3/4″, but predominantly above 3/8" and designed to meet the Wisconsin DOT spec for Coarse Concrete Aggregates #1 (AASHTO No. 67). We stock Washed 1 Stone at our Lisbon Pit/Quarry.
The particle size distribution, or gradation, of an aggregate is one of the most influential aggregate characteristics in determining how it will perform as a pavement material. In HMA, gradation helps determine almost every important property including stiffness, stability, durability, permeability, workability, fatigue resistance, frictional resistance and moisture susceptibility (Roberts et ...

Jan 24, 2013· The maximum aggregate size is defined as the smallest sieve size that requires passing. For example, in the following gradation: By the CT 382 definition, the maximum aggregate size is 3/4" and the nominal maximum aggregate size is 1/2".
Once packed, this stone will be as hard as concrete, and than you can spread a washed stone over the top. #78 or Pea Gravel Mainly gray in color with some tint of blue, however this stone averages 1/4 ". The small size has lead to the nick name of Pea Gravel, and is very easy to walk on making it great for walkways and sidewalks.
