Laurel Aggregates supplies a variety of high quality crushed stone aggregates, CO2 absorbtion stone, and rip rap material that meets any specification.
Pea Gravel The basics: Pea gravel is a small, rounded rock that got its name because the rocks are about the size of a pea. In reality pea gravel comes in different sizes — 1/4 inch, 1/2 inch and 5/8 inch are common sizes.
Aggregate sizes Fine aggregate is material that will pass through a 4mm sieve. Generally fine aggregate is a naturally occurring sand material, crushed rock material, or a combination of both.
Our aggregate products range in size from Rip-Rap, where each stone may weigh several tons, to manufactured sand for use in concrete and asphalt products. The numerous sizes and gradations are determined by their intended use and each complies with the specifications established by governmental agencies or our customer's requirements.

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 ...
Our Gray Tan Crushed Stone is a blend of gray, tan and brown stone crushed to various sizes. The earth tone color range works well with many natural settings. There are many uses including; Driveways, walk and pathways, tar and chip applications and exposed aggregate concrete.

The sieve analysis determines the gradation (the distribution of aggregate particles, by size, within a given sample) in order to determine compliance with design, production control requirements, and verification specifications.
Choosing Decorative Aggregate. The color palette of an exposed aggregate surface is largely determined by the type of decorative stone that's used. Aggregate selection can also have a big impact on the total cost of the project. ... Aggregate size and shape vary, too. The size, which can range anywhere from 3/8 inch to 2 inches or more in ...
· LCruiser: The coarse aggregate size number designation comes from ASTM C 33 Table 2. It takes into account MSA and grading characteristics. No 1 is the coarsest with largest MSA and No. 8 is the finest and has the smallest MSA.

Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete.
A coarse aggregate which has the sizes of particles mainly belonging to a single sieve size is known as single size aggregate. For example 20 mm single size aggregate mean an aggregate most of which passes 20 mm IS sieve and its major portion is retained on 10 mm IS sieve.
For asphalt pavements, different size rocks are crushed and aggregates are blended into graduated sizes to provide the strongest, best packing structure while allowing enough extra space for the asphalt binder and some "breathing" space (air voids).
EFFECTS OF AGGREGATE TYPE, SIZE, AND CONTENT ON CONCRETE STRENGTH AND FRACTURE ENERGY By Rozalija Kozul David Darwin A Report on Research Sponsored by THE NATIONAL SCIENCE FOUNDATION
Classification of Aggregates Based on Size. Aggregates are available in nature in different sizes. The size of aggregate used may be related to the mix proportions, type of work etc. the size distribution of aggregates is called grading of aggregates.
The coarse aggregates should be properly graded, and the gradation becomes more and more important as we increase the maximum size of coarse aggregate because of greater voids, which needs to be filled to attain the desired compressive strength.
