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