Cracks in Pavement Quality Concrete (PQC)
unevenness in the pavement which affect the riding quality. Diamond grinding is usually done to restore the pavement if the average faulting reaches 4 mm. Diamond grinding is nothing but removal of thin top layer of hardened PQC (4 to 6 mm) by means of closely spaced diamond saw blades so as to improve the pavement ridability.
