Grooving & Grinding
Diamond Coring provides grooving and profile grinding services to restore riding quality to concrete roadway/runway surfaces and enhance safety on walkways such as ramps and loading docks. Profile Grinding is cost effective for resurfacing concrete pavement and helps to ensure it remains skid-resistant. Grooving provides improved drainage on roadways/runways and increases friction which reduces hydroplaning and enhances overall road safety. Grooving on ramps is especially helpful in reducing or even eliminating hazards often associated with speed.
Contract Grooving Services for Bridges, Runways, Roadways
Diamond Coring has an entire division which specializes in pavement grooving and runway grooving services. Grooving is particularly helpful in significantly improving skid resistance and overall safety on roadway/runway surfaces by enhancing drainage and reducing pavement drying time.
Among our specialized grooving services, Diamond Coring offers
Bridge Deck Grooving
Recognized by Departments of Transportation as an effective method to reduce hydroplaning, increase water drainage, and enhance vehicle control especially in inclement weather, bridge deck grooving is the process of creating patterned grooves that allow for the displacement of water between the deck surface and the vehicle tire tread. Diamond Coring's trained professionals will ensure you meet the highest safety standards for your newly constructed or re-constructed bridge deck.
The purpose of runway grooving is to eliminate hydroplaning on wet runways, resulting in shorter braking distance of aircraft on wet pavement. The FAA has observed that transverse-grooved surfaces drastically reduce all types of skids on wet or flooded runways and provide positive nose-wheel steering during landing roll-out. Grooved surfaces also prevent the onset of drift and weathervaning. Pilots find overall ground handling and stopping characteristics on grooved surfaces a dramatic improvement over un-grooved surfaces. Grooved surfaces also prevent the onset of drift at touchdown in flooded areas due to high cornering forces. From the pilot's point of view, the overall airplane ground handling and stopping characteristics on grooved surfaces show remarkable improvement over other surfaces.
Restore runway friction with runway re-grooving. Diamond Coring offers airports with grooved, rigid and flexible pavements an innovative technique to extend the longevity, performance and functionality of those pavements.
Re-grooving is an alternative for runways with groove deterioration. Types of groove distress include normal wear, groove closure, rubber deposits, rounding and erosion. Groove collapse commonly occurs in wheel line rutting areas. This innovative technique consists of re-grooving the existing groove profile in bituminous HMA or concrete runway surface by using existing grooves and alignment.
Structural maintenance of the macro texture is essential for proper drainage and skid resistance:
"3-5. GROOVE DETERIORATION. Periodically, the airport operator should measure the depth and width of a runway's grooves to check for wear and damage. When 40 percent of the grooves in the runway are equal to or less than 1/8 inch (3 mm) in depth and/or width for a distance of 1,500 feet (457 m), the grooves' effectiveness for preventing hydroplaning has been considerably reduced. The airport operator should take immediate corrective action to reinstate the 1/4 inch (6 mm) groove depth and/or width."
Diamond Coring can evaluate your runway macro texture condition and provide you with a survey necessary to improve critical groove failure areas. We have the equipment, knowledge, and experienced personnel which ensures our clients maintain the acceptable friction value mandated by the FAA for runways and high speed turn offs.
Contract Profile Grinding Services
Grinding provides a smooth riding surface that is often as good as or better than new pavement. Diamond Coring's grinding equipment is capable of corrective (bump) grinding or continuous grinding depending on the job requirements.
Utilizing diamond profile grinding, a concrete pavement restoration (CPR) technique used in conjunction with other CPR techniques, a variety of surface imperfections on concrete pavements can be corrected. Diamond highway grinding is a proven and cost effective means of restoring vehicle ride quality, extending pavement life and enhancing skid resistance.
