Corrective or Bump Grinding
The Department of Transportation (DOT) has accepted and approved this method to improve the ride quality and to meet stringent profile specifications. The application is available for both concrete and asphalt pavement used in the construction of roadways, airports, and bridges.
Aside from that, it is commonly performed on isolated portions of pavement or continuous methods, depending on job requirements. The corrective or bump grinding practice is used to avoid possible ride quality penalties and in some cases, contractors may achieve ride quality bonuses.
Diamond Grinding Concrete Pavement Restoration (CPR)
This continuous grinding method extends the existing pavement life by restoring ride quality. The process removes all joint curling, slab faulting, rutting, and leaves a new skid-resistant surface. It is also performed with other CPR techniques such as slab repair, dowel bar retrofit, and joint resealing. The method has been the most commonly used method for extending and improving pavement life and safety.
Diamond Grinding New Pavement
This grinding method is used to improve the ride quality and meet strict conditions. It also adds a corduroy skid-resistant texture, which is a proven process in extending pavement life with major safety benefits.
Transverse Bridge Deck Grooving
Grooving is an alternative for tining. Transverse safety bridge deck grooving forms several drainage channels that help dissipate water rapidly. Some states have adopted this practice to reduce hydroplaning, freezing and wheel spray by increasing traction. The grooving patterns and other specifications may differ from state to state. In addition, the random patterns created are commonly used to reduce tire noise.
Runway and Taxiway Grooving
This has the same general safety principles as in transverse bridge deck grooving. The Federal Aviation Administration (FAA) has adopted this process. Grooving patterns are typically .250 wide x .250 deep on 1.5-inch center spacing.
Longitudinal Pavement Grooving
The same general safety principles are still applied in this method, but the grooving pattern is cut longitudinal. This is often performed on larger quantities of highway pavement when surfaces are worn. It’s more productive and is a cost-reducing approach. Diamond grinding is the best alternative.
Other Grooving Applications
Some of the grooving methods we provide can be applied to parking decks and parking lots. Grooving is also a standard process applied to livestock and agricultural roads to increase traction.
Utilizing our high-speed inertial profilers we are able to produce profile traces which show the actual shape of the pavement surface. This then can be analyzed to determine ride quality. Using established specifications for each project, we are able to measure the ride quality results, produce pay adjustments schedules and identify localized roughness.
