Gravel Size Gradation Chart which stone to choose
Products in this range are notably more compactible and suited for creating a base layer -such as Crusher Run, Screenings, Sand and Soil. For support of heavy vehicles – choose our #3 or #4 stone. For standard driveways – choose our #57 or #67. For more elaborate driveways – choose our 1/2” to 2” river gravel.

Maupin (7) has reported a laboratory investigation of the effect of particle shape on the fatigue behavior of an asphalt surface mixture. Three aggregates: round gravel, crushed limestone and slabby slate were used in that study.

Evaluation of Recycled Base Aggregates
Analysis of the particle size distributions for the investigated crushed stone aggregate (CA), RCA, and RAP base materials indicated high sand size fractions in both RCA and RAP base materials compared with CA base materials. The RCA base materials exhibited the highest absorption and high percentages of mass loss in Micro-Deval test.

addition, aggregate resistance to degradation is important in mixes such as Stone Matrix Asphalt (SMA) and Open Graded Friction Course (OGFC) that rely on stone-to-stone contacts among coarse aggregates. Some aggregates in these mixes fracture due to the high stresses at contact points.

The Complete Guide to Crushed Stone and Gravel
Unlike crushed stone, gravel is usually sold and used in its natural state. If it is crushed, gravel loses its unique smooth rounded texture and becomes crushed stone. It is important to note that some contractors refer to any stone in certain size ranges as “gravel,” even if it is crushed stone.

The aggregate criteria for SMA are more stringent than for Superpave and Marshall mixes. Crushed stone aggregates are required with stricter flat and elongated, sand equivalent and fine aggregate uncompacted voids requirement. SMA gradation and VMA requirements are different and minimum asphalt contents are specified for SMAmixes.

Crushed stone is a type of medium-sized gravel that is formed by mechanically crushing stone. Most commonly, limestone, dolomite, or granite is crushed to form the crushed stone. In certain definitions of the term, crushed stone is not considered gravel since it is a processed rather than naturally-occurring rock fragment.

Crushed Stone Aggregates
Crushed stone aggregates are produced by crushing quarried rock, then screening it to sizes appropriate for the intended use. Production of crushed stone has three stages: Primary crushing to break down the stone to a manageable size; secondary and tertiary crushing to render the rocks into sizes specific to their applications; and screening to separate the crushed stone for further processing
