Grinding:

Diamond grinding is a concrete pavement restoration technique that corrects irregularities caused by construction curling, slab warping, faulting, and roughness and restores rideabliity.  Partial-depth repair may be used to repair spalled areas at joints and cracks.  The most immediate effect of diamond grinding is a significant improvement in the riding smoothness of a pavement. Another very important effect of diamond grinding can be the significant increase in surface macro-texture and consequent noise reduction and safety improvement. Safety can be improved by a temporary increase in skid friction resistance and a reduction in the potential for hydroplaning. 

Grooving:

Grooving consists of cutting deeper channels that provides better drainage of water between the tires and the pavement surface and thus preventing skidding and hydroplaning.  On highway pavements grooves are sawed in the longitudinal direction to improve the directional control of vehicles, especially on curves.
