Modern asphalt facilities are located throughout North and South Carolina, capable of producing a variety of asphalt mixes for use in Sloan Construction Company projects.
In our design laboratory and through our association with parent company, Reeves, 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”, a new concept in environmental design.
Cold Mix Asphalt mixes 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 (HMA) is a combination of aggregates, hydrated lime, and a bituminous binder called asphalt cement. Sometimes additives are used (for example 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.
Warm Mix Asphalt is the generic term for a variety of technologies that allow the producers of hot-mix asphalt pavement material to lower the temperatures at which the material is mixed and placed on the road. Such drastic reductions have the obvious benefits of cutting fuel consumption and decreasing the production of greenhouse gases. In addition, potential engineering benefits include better compaction on the road, the ability to haul paving mix for longer distances and the ability to pave at lower temperatures.
Southeast Emulsions produces asphalt emulsions and polymer modified emulsions, which are used in virtually every type of pavement preservation including surface treatments, cold mixes, recycling and tack coats. They hold AASHTO (American Association of State Highway and Transportation Officials) accreditation for Emulsified Asphalt testing. They formulate new products using select raw materials and then test them extensively in their in-house laboratories and testing facilities. From there, they manufacture them using state-of-the-art plants and equipment.
Examples of product development include FastTack®, which is used to aid asphalt pavement adhesion to underlying surfaces, and FiberMat®, a fiberglass-reinforced binding layer used with a traditional chip
Once extracted by drilling and blasting, granite is crushed to various sizes to produce aggregate. Aggregates are essential components used in the manufacturing of asphalt and concrete. Aggregates are also commonly used on construction sites as a base to cover the subgrade and for the installation of best management practices for erosion control. The production of aggregate products allows us to meet all construction needs. With the strategic location of our quarry, we supply to both North Carolina and South Carolina.
