Fracturing concrete then rolling it removes existing pavement distresses and eliminates future slab action delivering a structurally sound base that prevents reflective cracking in the overlay.

“Modified rubblisation” describes the process of producing larger broken particle sizes that compensate for a weak subgrade/base.

Cracking concrete slabs to reduce their effective length, then seating the cracked slabs to re-establish support between the sub-base and the slabs.

This minimises the occurrence and severity of reflection cracks in the overlay caused by slab action.

Some specifications require the road be opened to traffic soon after the crack process to accomplish the seating prior to paving the overlay. Other specifications require a proof roller be used to seat the cracked concrete.

This method employs more energy than crack & seat in order to sever any reinforcing steel thus causing more spalling of the concrete surface.

Specifications typically require several passes with a proof roller to seat the broken concrete.

We break concrete pavement down to a size that meets your removal, hauling and crushing needs saving you time and money.

This is typically a faster, more efficient means of breaking concrete than traditional methods.
