Hydroplaning
on Pavements
If you have increased accident rates or vehicles have experienced hydroplaning on either concrete or asphalt pavements, you need to perform:
Longitudinal Grooving
​
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.

Asphalt Diamond Grinding
Road owners increasingly see benefits of diamond grinding and grooving both new and existing asphalt pavements. Safety grooving, another diamond saw-cut surface texture, is being applied to asphalt pavement.

During Adverse Conditions, Decelerating to Stop Demands More From Crew and Aircraft
Decelerating an aircraft to a stop on a runway becomes significantly more critical in adverse conditions like heavy rain, marginal visibility, and gusting crosswinds. The U.S. National Aeronautics and Space Administration (NASA) and the Federal Aviation Administration (FAA) conducted specialized tests confirming that hydroplaning occurs at substantially lower speeds than previously noted. Despite technological advances like runway grooving, anti-skid braking devices, and high-pressure tires, several major runway overrun accidents still occur annually due to unsuccessful braking.

Diamond Grinding: A Safe, Sustainable, Quiet and Cost-Effective Solution to Better Roadways
This white paper presents several case studies demonstrating the benefits of diamond grinding for maintaining and improving roadway conditions in Arkansas, California, Kentucky, and Phoenix. The importance of managing slurry/concrete grinding residue (CGR) for environmental compliance is also emphasized throughout the various case studies.
