Rubblization is the process of fracturing the worn-out concrete into small, typically 2- to 6-inch, pieces and converting it into an interlocked but flexible base material. The rubblizing process breaks the bonds between any reinforcing steel and the concrete, eliminates slab movement, and nearly eliminates the possibility of reflective cracking.
Hydraulic breakers are the oldest hydraulic attachments for carriers. The first serial manufactured rock breaker was the Krupp HM 400 in 1967 and the patent was secured in 1963. Excavator jack hammers are impact devices designed to break any kind of rock or concrete with any hardness or physical property. They have a wide range of applications ...

Abstract. When stress in concrete exceeds certain threshold value, microcracks are nucleated, these microcracks can propagate and coalesce forming macrocracks, resulting in the gradual decay of the mechanical properties of concrete and eventual failure of the concrete structures. For safety concerns, one needs to develop …
