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.

The Next Generation Concrete Surface (NGCS)
Construction for The Finish Line, also known as Section 6, includes 27 miles of new interstate highway, as well as work on the heavily traveled I-465 between I-70 and I-65 on Indianapolis’s southwest side. It entails either replacement, rehabilitation or new construction for 42 bridges. Concrete paving will be used on all of them, and many will be surfaced using Next Generation Concrete Surface (NGCS).

Revolutionizing Rut Repair with Calcium Sulfoaluminate Cement (CSA)
The challenge of repairing wheel ruts on concrete pavements is a persistent issue for infrastructure maintenance, particularly in regions with heavy snowfall and tire chain usage. A promising rut repair method calcium sulfoaluminate (CSA) cement, was chosen as a cost effective, easy-to-use and longer-lasting repair material for a project executed by ACME Concrete Paving Inc. in collaboration with the Washington State Department of Transportation (WSDOT), to remediate pavement ruts.

Study of the Effect of Grooving on Motor Vehicle Accidents
Diamond grooving has proved to be one of the most cost-effective safety programs of the Department of Public Works. Motorcycle accident reports were reviewed from both grooved and ungrooved sections. The Department of Public Works' accident experience reveals that grooving has yielded a 10% reduction in total accidents, 50% reduction in fatal accidents and 70% reduction in wet pavement accidents.

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.

Performance of Grooved Bituminous Runway Pavement
Diamond grooving of flexible (and rigid) pavements is a technique performed to reduce hydroplaning and to improve friction on all runways that serve turbojet aircrafts. Despite their widespread application, grooves in hot-mix asphalt (HMA) runways are prone to several distresses that limit their longevity at the desired level of serviceability.
