Blacksburg Quarry

IMG_1863In Cherokee County, near Blacksburg, South Carolina, lies a type of granite which is an essential building component for roads, bridges, homes and schools in communities throughout the Carolinas.

In 2011, Sloan Construction received all local, state and federal permits to begin mining this granite at the Blacksburg Quarry for use in construction projects along the I-85 corridor in North and South Carolina. The quarry is estimated to produce about one million tons a year of construction grade-aggregate, and will be both North Carolina and South Carolina Department of Transportation-certified.

The material being mined has a Los Angeles (LA) abrasion test in the mid 30’s, signifying the long term durability and soundness of this material meets or exceeds the needs of our customers.

The Sloan Blacksburg Quarry covers an area of approximately 54 acres within a 314-acre tract, and is strategically located along I-85, southwest of the SC-198 interchange.

Asphalt Mixes

In our design laboratory and through our association with parent company, Colas, we have the ability to provide conventional asphalt mixes as well as the most technical applications which address properties such as skid resistance, noise levels, high durability, and even “warm asphalt,” which is a new concept in environmental design.

Cold Mix Asphalt

Cold Mix Asphalt combines emulsified asphalt with aggregate. While in its emulsified state, the asphalt is less viscous and the mixture is easier to compact and work with. Cold Mix is commonly used as a patching material on lower traffic volume roads.

Hot Mix Asphalt

Hot Mix Asphalt is a combination of aggregates, hydrated lime, and a bituminous binder called asphalt cement. Sometimes additives are used, i.e. rubber from old car tires or rejuvenators, and, increasingly, reclaimed asphalt from old roads called RAP (recycled asphalt pavement). The aggregates that are added are crushed stone and sand mixed in a predetermined proportion to obtain the desired properties.

DSC_0044Warm Mix Asphalt

Warm Mix Asphalt is the generic term for a variety of technologies that allow the producers of hot-mix asphalt pavement material to greatly decrease the temperature at which the material is produced and placed on the road. Such drastic reductions have the obvious benefits of cutting fuel consumption and reducing the production of greenhouse gases. In addition, to the environmental benefits warm-mix offers better compaction on the road, and the ability to haul paving mix roughly 50% further than traditional methods.

Crumb Rubber Mix

Crumb Rubber Mix is produced by crushing rubber tires into fine granules and incorporating it into an asphalt mix. The blended rubber improves the performance aspects of asphalt, such as thermal susceptibility, elastic behavior, fatigue cracking resistance and aging stability.
