Aggregate Gradations for Concrete Pavement Mixtures
stone, Sr. is an empirical approach to aggregate proportioning based on his experience in producing lean concrete mixtures with acceptable workability and reduced segregation [11, 12]. The Coarseness Factor Chart plots two different parameters that help divide a combined aggregate gradation into coarse, intermediate, and fine aggregate sections.
Understanding Crushed Stone Grades
Crushed stone #8 includes stone between 3/8" and ½". This is the most common stone used for concrete mixes. #10. Crushed stone #10 is known as screenings or dust.

A Review of Concrete Aggregate Gradations
Aggregate Grading. The aggregate gradation and content can impact several properties of a concrete mix: Finishability, workability, pumpability, strength, permeability, and shrinkage. Aggregates having a smooth grading curve size will generally produce mixtures with fewer voids between particles.

A Simple Guide to Aggregate Gradation & Sieve Analysis
This gradation contains a wide range of different sizes of aggregates. Voids created by larger rocks are filled by smaller rocks and fines. As a result there are fewer vois and the material compacts well. This type is typicalls used for recycled concrete aggregates, roadbase, and concrete & asphalt stone products.

AASHTO #10 Crushed Stone
Crushed stone is a popular choice for underground pipe bedding. The aggregate helps level and support the pipe. 6. Concrete Block Production. In addition to constructing concrete pathways, #10 crushed stone is a great option for concrete block manufacturing. Because concrete is inherently porous, it absorbs any moisture it comes into contact with.
