Groove Cutting is the technique to provide control joints in Concrete to guide cracks along a predetermined line and to help accommodate the movement of the concrete and avoid Cracking of Concrete and long-term damage.
Concrete expands and contracts constantly with changes in the temperature, the moisture content of the air and due to drying of cement which results in shrinkage. The movements result in stress that can cause cracks in the concrete and destabilization of the base..
Concrete roads are durable and safe. They are considerably less prone to wear and tear defects like rutting, cracking, stripping, loss of texture, and potholes that can occur with flexible pavement surfaces. This low maintenance requirement is one of the principal advantages of concrete pavements. There are well-designed concrete pavements that have required little or no maintenance well beyond their 40-year design lives. Less maintenance also means fewer traffic delays, a huge advantage on some of our already congested highways.
