Asphalt Manufacturing – Commitment to Innovation
Since January 2006, we have continuously invested in a 7-acre facility devoted to producing sustainable pavement materials. Our experienced team created a new crushing and screening operation to produce high quality crushed concrete in a clean and efficient manner. In addition, we installed a custom built pugmill.
Sustainable aggregate products use resources as efficiently and effectively as possible. They are also:
- Environmentally conscience
- Economical
- High Quality Base material for the value-focused customer
Crushed Concrete
RC-6 is an excellent recycled product that can be used as base material for roadways, sidewalk, curb, etc. We also offer RC-2 for construction entrances, stabilization, etc. These products have good performance over time.
Recycled Aggregate Blends
This product is a blend of RC-6 and screened millings. It has excellent stability, compactibility, and load bearing characteristics. The blending takes place in our plant, where moisture content is controlled for optimal compaction. It has superior stability to crushed stone / concrete products. The mix gains stability as the cement in crushed concrete and the asphalt in the millings cure.
Foamed Asphalt
This product will replace both a stone base course and the asphalt base course. It is 40% screened millings and 60% crushed concrete blended in a pugmill where 7% water and 3% foamed asphalt are introduced into the mix.
Using a specialized manifold to force water and air through conventional PG 64-22 liquid asphalt produces foamed asphalt. The high temperature of the asphalt causes the cool water to expand rapidly.
This expansion causes the asphalt to form miniscule air bubbles, in other words “foam”. During blending, the foamed asphalt’s volume is ten times the size that the liquid asphalt alone would be.
The benefit of the foam formation is that the liquid asphalt has a much greater surface area and much lower viscosity. Th0is causes it to bind more readily with aggregates.
The mix will not compact until the air bubbles have been driven from the liquid which allows stockpiling of the material for up to forty days.
Foamed asphalt base is placed in a conventional paving operation. It bonds extremely well. The joints are nearly impossible to detect. Its stability is similar to asphalt and its load bearing is similar to concrete. Due to 14% air voids in the mix, it is not suitable as a surface course. Foamed asphalt is a stable and extremely strong base material. There is no heating or drying of the aggregates.
