Asphalt

Modern asphalt facilities are located throughout the states of Missouri, Arkansas and Illinois, capable of producing a variety of asphalt mixes for use.



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”, a new concept in environmental design.

Cold Mix Asphalt

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

Hot Mix Asphalt (HMA) paving mixtures consist of combining liquid asphalt, construction aggregates (crushed stone, gravel or sand), additives and modifiers. 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 exact mix of ingredients is customized for each project based on a number of factors, including local weather patterns and expected traffic conditions. When expert assistance is required, our Certified Lab Technicians work with customers to optimize mix designs. Asphalt is the preferred paving surface US roads and highways. Asphalt also remains a popular surface for parking lots, walking trails and bike paths.

Delta Companies has state of the art asphalt plants that are DOT Certified. Each region has quality control laboratories and certified lab technicians.

Warm Mix Asphalt

Warm Mix Asphalt paving mixtures – is a newer paving product – growing in popularity.  It consists of combining liquid asphalt, construction aggregates (crushed stone, gravel or sand), additives and modifiers. Warm-mix is produced at lower temperatures, thereby reducing energy consumption during production and minimizing fumes during laydown. 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.
