Aggregate Sales

Earth Work Solutions is a supplier of many types of aggregate that will suit your needs. We sell, deliver, and place the following aggregate resources:

  • Granite
  • Limestone
  • Scoria
  • River Gravel
  • Sand
  • Natural Calcined Bauxite

Our New Aggregate Source – Lake Ranch Pit

We are proud to announce a new aggregate source in Northeast Wyoming. Our aggregate is an Natural Calcined Bauxite which is similar, but structurally and chemically superior, to granite. This rock is extremely hard and durable and has a very rough surface. The sales yard is located near Carlile, WY, 3 miles west on Cabin Creek county road (48 miles from the Garner Lake Road exit on I-90). Its location will substantially decrease your freight costs to the Powder River Basin.

The properties of this premium aggregate make it the hardest, cleanest, most durable, and best performing aggregate within the market area.

Toughness and Abrasion Resistance

Los Angeles Abrasion Test (ASTM C 535)

The Los Angeles Abrasion Test, or L.A. Wear, is designed to measure the ability of an aggregate to resist crushing, disintegration, or degradation over time. The results are expressed as a percentage of loss with a lower percentage representing a more durable and wear resistant material. Earth Work Solutions Bauxite has a Los Angeles Abrasion of 18%, making it an extremely durable and resilient aggregate affording less wear, longer life, and less dust.


Compressive Strength

Earth Work Solutions Bauxite has a compressive strength of approximately 25,000 psi which is significantly higher than our nearest competitor.

Durability and Soundness

Soundness Test (ASTM C 88)Before-and-After-Soundness-Testing-Example

Aggregates must be resistant to disintegration or breakdown due to weathering (freeze/thaw or saturation/drying) or they may prematurely wear. A soundness test determines an aggregate’s resistance to weathering and, therefore, is an excellent indicator of long-term durability. The results of a soundness test are expressed as a percentage of loss or percentage of material broken down by the process. A lower percentage indicates lower breakdown and more durable, longer lasting material. Our Bauxite exhibits a soundness loss of between 0.00% and 0.04%. This extremely low value means that our aggregate will outlast competitive aggregates such as limestone, scoria, and river gravel by at least 3 times.Soundness-Loss

Particle Shape and Surface Texture

Percent Fractured Face (ASTM D 5821)

Earth Work Solutions Bauxite contains 100% fractured surfaces having a rough texture. This allows for excellent binding characteristics and more consistent compaction.

Flat or Elongated Particles (ASTM D 4791)

Flat or elongated particles can cause problems in HMA because they tend to break or reorient due to compaction. Our aggregate contains less than 0.5% flat or elongated particles for more consistent and longer lasting concrete and asphalt.

Cleanliness and Deleterious Materials

Sand Equivalent Test (ASTM D 2419)

A sand equivalency test is used to determine the amount of fine dust or clay-like material contained in an aggregate. A higher sand equivalence represents less dust particulates contained in the sample. Our aggregate has a sand equivalency of over 85% which means it will provide excellent cohesion when used in HMA or PCC and will create less dust on gravel surfaced roads and while handling.

Specific Gravity

Specific Gravity Test (ASTM E 12)

The specific gravity of our aggregate is lower than that of our competitors and therefore will require less tonnage for the same amount of road or rail coverage or to produce a cubic yard of concrete.


Our Bauxite has an absorption of 0.05% which translates into less AC for the same tons of mix with less water absorption resulting in a more stable and consistent mixture.

Polishing and TractionInsoluble-Residue

Insoluble Residue Test (ASTM D 3042)

An Insoluble Residue Test determines an aggregate’s ability to resist polishing. Aggregates which polish excessively will become slippery over time resulting in loss of traction. The results of the insoluble residue test are expressed as a percentage where a higher percentage means that the material is more resistant to polishing. Earth Work Solutions Bauxite has 98% insoluble residue resulting in a long-lasting, slip-free surface.

Chemical Properties

Alkali-Silica Reaction

Alkali-Aggregate reactions occur between the alkali contained in cement and elements in the aggregate. The most common reaction of this type is between alkali and silica. This reaction causes map or pattern cracking in PCC. Our aggregate has an Alkali-Silica Reactivity of less than 0.01 after a 28 day test. This makes our phonolite very well suited for highly stable concrete which can mitigate ASR problems without the use of fly ash or lithium.
