• Aggregate Base Course vs. Crushed Concrete Aggregate

    Crushed concrete aggregate base course is made from recycled concrete aggregate, which is created by grinding concrete that’s been reclaimed from demolished highways, buildings and other structures. The concrete from these sites is then processed to remove metals, and screened to appropriate sizes.

    What is crushed aggregate base? Crushed Stone ReAgg

    When doing structural foundations or base course under concrete slabs and asphalt pavement roadways, Aggregate Base is in use. It can be placed by attentive spreading then compacting. The sub-base if formed by dust and small chipped aggregate layers, typically Crushed Fines. The crushed aggregate base lays on heavy traffic or driveways areas.

    Crushed Gravel Base Course ad-diffusion.ch

    While aggregate base course is typically made from materials mined directly from the earth, aggregates can also be made from recycled concrete, called crushed concrete aggregate.

    Crushed Aggregate Base Course Specifications for

    Aggregates are materials such as gravel, sand and crushed stone that provide an important ingredient in concrete. An aggregate base course is the layer of soil installed between the surface pavement layer and the foundation soils of either asphalt or concrete pavement.

    Development of a 3/4-Inch Minus Crushed Base Course

    Crushed and processed aggregate are typically a cost effective means of carrying loads and reducing the thickness of the asphalt layer in paved roads—but, for some projects (such as in Montana), obtaining materials that meet the current specifications for crushed base course is becoming uneconomical due to declining resources. Could a more attainable ¾-inch minus gradation serve infrastructure?

    Crushed stone comprises 30% of the aggregate produced in the area and plays a major role in regional aggregate resource needs. Broken glass or cullet are sometimes used in aggregate base courses.
