COLD MIX ASPHALT
Mixes are designed for purpose and climate.
Cold emulsion mixes are basic aggregate-asphalt emulsion mixes classified by their use, composition and storability. Mix designs are required to determine the grade and percent of emulsion used, as well as the workability, stability, strength and moisture susceptibility. Mixes are designed for purpose and climate.
Features and Benefits
- Tailor-designed for optimum performance of varying raw materials and climates
- Control over characteristics such as set time, mix time and strength
- Economical: eliminates the need to dry or heat aggregate
- Safety: cold emulsions are safer than super-heated asphalt cements
- Option to mix in place or plant mix and stockpile
- Wide choice of processes to meet your paving needs (repair, restoration, and base and wearing courses)
- Suitable for new construction or rehabilitation
- Processes to meet secondary or primary road demands
- Utilization of standard paving equipment (paver or blade laid)
- Cost effective way to maximize the life of the road
Open graded mixes are high air void mixes that result in quick drainage, improved skid resistance and reduced hydroplaning and spray. Open graded mixes reduce road noise and are an economical alternative to sound barriers, while the increased durability improves rut resistance.
Dense graded mixes are medium air void mixes that are high in strength and use affordable crusher-run aggregates. Low water impermeability greatly improves freeze/thaw characteristics.
Mixes can be made with 100% recycled asphalt pavement (RAP). These mixes are economically and environmentally friendly. RAP mixes can be crushed, graded, mixed and laid on-site using custom-engineered rejuvenating emulsions.
All forms of cold mix can be stockpiled. Mixes are specially formulated to meet the desired life of the stockpile. Their uses range from maintenance to base and wearing course paving and will allow for flexibility around unforeseen delays and varying weather conditions.
