Paving Quality Concrete

The material, techniques / System for repair the PQC cracks should be such which will have durability of minimum 10 – 15 years or as per the designed life of pavement. Otherwise water may penetrate from these cracks and reach sub-grade and embankment level causing settlement. This will ultimately damage the pavement. Hence it is necessary that a methodology and guidelines for the repairs & rehabilitation of such cracks in PQC be developed. Normally the repair material should remain flexible enough to accommodate anticipated expansion & contraction, water-tightness etc.
