 Specialized equipment is used to rubblize the concrete pavement and separate it from reinforcement. Each pass of the breaker shoe must overlap the previous pass by a minimum of 1 inch for resonance frequency breakers. Each pass of a multi-hammer breaker typically completes an entire lane width. Throughout the rubblizing process, it is imperative to ensure the broken pavement does not exceed 10 inches as its greatest dimension. Any large segments of broken concrete pavement exceeding this dimension must either be eliminated or further broken down to achieve a smaller dimension. The Contractor must monitor the condition of the breaker shoe and replace it as necessary when it shows signs of wear. The pavement breakers should operate at a speed of 0 to 3 mph.

 When exposed reinforcement is encountered, it must be marked, cut off below the surface, and removed. Embedded reinforcement can remain in place.
