Asphalt and Concrete

Asphalt

When asphalt enters the landfill, it is kept out of the active cell and reused in roadways and in areas where the public drive, making our landfill more accessible in wet weather.

Concrete

The concrete that enters the landfill is kept separate until a grinder is brought in to grind it into an aggregate.

Uses for Recycled Concrete

Aggregate base course (road base)

The largest application of recycled concrete aggregate (RCA) is for aggregate base course in road construction. This is the center laver of the road bed. A cross-section of pavement would show dirt, or subgrade, as the lowest of three levels, layered on top by aggregate base course, and finally capped on top by pavement, either concrete or asphalt. Use in aggregate base course is a relatively simple process, and one most widely accepted for recycled concrete by Departments of Transportation. RCA can be used in ready mix concrete. This approach is still in its still in its infancy.

Soil Stabilization

Where soil stability is an issue, the load bearing capacity of that subgrade can be improved through the incorporation of recycled aggregate, lime or fly ash. The process changes the water susceptibility of subgrade, thereby increasing stability.

Pipe Bedding

Recycled concrete can serve as a stable bed or firm foundation in which to lay underground utilities.

Landscape Materials

Recycled concrete has been used in various landscape settings, including paving stones, boulder/stacked rock walls, underpass abutment structures, erosion structures, water features, retaining walls, and other uses.
