What does rubblizing concrete involve?

Rubblizing concrete refers to the process of breaking existing concrete pavement into smaller pieces or fragments. This technique is commonly used in road rehabilitation projects where the existing concrete surface is too damaged or unsuitable for continued use. By cracking and fracturing the concrete, the material is then transformed into a more manageable and workable form. This allows for an improved base for new pavement layers to be placed over, ensuring better bonding and stability.

The end result of rubblizing creates a solid base that can absorb stresses and prevent reflective cracking in the new overlay, thereby extending the lifespan of the pavement structure. This is critical in maintaining road safety and performance without the need for complete removal and replacement, which can be time-consuming and costly.
