If you have increased accident rates or vehicles have experienced hydroplaning on either concrete or asphalt pavements, you need to perform:
Automobile accidents tend to increase when there is a loss of friction between the tire and pavement surface due to slippery
conditions. Highway departments have found that the best way to decrease accidents during inclement weather is to remove water from the surface and increase the traction between the tire and the road.
Experience has shown that grooving a pavement’s surface is a very effective method to increase traction, reduce hydroplaning and minimize splash and spray as well as provide a more effective braking surface. This easily constructed and economical surface treatment provides the superior traction needed for vehicles to maintain control while driving in wet, dangerous conditions.
Municipalities and departments of transportation world wide are finding that grooving has a two-fold benefit: it increases a driver’s safety while driving in wet conditions and at the same time, saves on the costs of replacing or overlaying the pavement surface.
