What is the objective of pavement grooving?

The objective of pavement grooving is primarily to minimize loss of friction. When grooves are cut into the pavement surface, they help channel water away from the tire-pavement interface, which improves traction. This is particularly important in wet conditions, as it reduces the likelihood of hydroplaning and enhances vehicle control. By improving friction between the tires and the pavement, grooving contributes positively to vehicle safety and operational efficiency on runways and taxiways.

While enhancing aesthetics and improving durability are also considerations in pavement design and maintenance, they do not directly relate to the primary function of grooving. Cost reduction is an important aspect of any infrastructure project, but the main focus of pavement grooving is specifically on enhancing surface performance and safety through improved friction.
