Potential Use of Crushed Concrete and Recycled Asphalt

Potential Use of Crushed Concrete and Recycled Asphalt Pavement as Backfill for Mechanically Stabilized Earth Walls Mechanically stabilized earth (MSE) walls (Figure 1) have been used throughout the U.S. since the 1970s. The popularity of MSE systems is based on their low cost, aesthetic appeal, simple construc-tion, and reliability. To ensure long-term integrity of MSE walls, select backfills

Recycled Concrete: The Pros and Cons Crushed Stone,

Concrete recycling plants, like the one operated by Braen Stone, work to crush the recycled concrete and screen it down to size. Any metal pieces, contaminants, or debris are removed from the concrete aggregate so that it is pure in its composition. In order to ensure that you get the highest quality RCA, it’s imperative that you buy from a reputable source that takes pride in excellent

Strength and stiffness of compacted crushed concrete

In Japan and many other countries, a great amount of crushed concrete aggregate (CCA) is being and will be produced by demolishing old and/or out-of-service concrete structures. The use of CCA as the backfill of soil structures, such as embankments and retaining walls, replacing costly selected natural backfill soil (i.e., well-graded gravelly soil) is highly required. This is because (1

What is crushed aggregate base? Concrete Recycling

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 Stone vs. Pea Gravel: What’s the Difference

Many contractors prefer to use ½” or ¾” crushed stone as a subbase material before laying concrete. Since it’s durable, it is also regularly used for backfill, drainage solutions, or pipe bedding. Larger crushed stone, such as CA6 or CA5, is typically used for parking lots, driveways, shoulder stone, or railroad ballast. While it is typically found in underground applications, there
