Airfield grooving is used to increase the friction of a wet surface by removing surface water. Jointline have many years experience at the installation of anti-skid grooving to asphalt and concrete runways at airfields both in the UK and Worldwide. It is also possible to install antiskid grooving on highways to give additional surface grip.

Grooving is always transverse to the direction of travel, and usually to within ten feet (three meters) of the runway edge to allow for the maneuvering of the equipment. The FAA standard is ¼" wide by ¼" deep on 1-1/2" centers (6mm x 6mm x 38mm). Other international standards include 4mm x 4mm x 25mm. Grooving can occur day or night.

In the mid 1980s, tests were performed on 12 different concrete and asphalt runways, grooved and nongrooved, including dry, wet, and snow, slush and ice-covered surface conditions. Over 200 test runs were made with two transport aircraft, and over 1,100 runs were made with different ground test vehicles.

Submit grooving sequence and method of placing guide lines to control grooving operation. Cut grooves in the [asphalt] [portland cement] areas as indicated on the drawings. Begin the grooving at one side of the usable [runway] [taxiway] and continue for the full width of the area.

Runway grooving can be used on both Portland Cement Concrete (PCC) and Hot Mix Asphalt Concrete (HMAC) pavement surfaces. 4.0 RUNWAY SURFACE TEXTURING For asphalt surfaces, the provision of surface texture may be achieved by the selection of the appropriate aggregate in terms of size, gradation, resistance to polishing and wear, and shape.

Grinding is often utilized for correction in longitudinal directions on asphalt, concrete pavements and bridge decks. Grooving involves multiple diamond blades moving in a transverse direction on a bridge deck to produce a mechanically tined surface for skid resistance and traction. Grooving & Grinding are ideal for: Bridge decks; Airport runways

An area of potential concern with the use of WMA on the surface of airfield runway pavements is the material response to surface grooving. If the asphalt binder in WMA is softer than that of comparable HMA because of reduced binder aging during production and placement, the WMA mixture may be more likely to experience groove closure or collapse.

The grooving machine is one of the Worlds largest and most efficient. We install 2/3 lights for runways, stop-bars and centerlights on taxiways. Saw-cut slotting in asphalt or concrete surface is performed with a special saw, driven by the same machine we are using for grooving.

Diamond Grooving & Bridge Deck Grooving. When it comes to grooving, our primary focus is safety. Grooving is designed to improve vehicle traction and reduce accidents. Patterned grooves in your roadway will displace water and significantly reduce the risk of hydroplaning. Our method will highly increase the friction and drainage of the roads.

Grooving. With this process, originally developed in the USA, a special device (BumpCutter) is used to cut narrow grooves, e.g. 3 x 3 x 20 mm, in concrete or asphalt pavements, thereby improving the drainage of water between tires and the roadway surface.

Grooving is undertaken on runways to avoid aircraft skidding incidents during wet weather conditions, as well as satisfying regulatory skid resistance requirements. Closure of the grooves is a common distress experienced at airports surfaced with DGA in Australia and has led to the investigation of stone mastic asphalt (SMA) as an alternate ...

Concrete Grinding & Grooving. Removing imperfections and enhancing the safety and ride of roadways and runways, that's what our diamond grinding and grooving services are all about. Penhall can provide every concrete solution you need to complete your project on time, on scope, on budget, and most importantly, safely. DIAMOND GRINDING.

Grooving production is contingent on many factors including type of material to be grooved (asphalt or concrete), the type of aggregate, dimensions of the runway, slurry disposal requirements, etc. but a reasonable expectation is from 400 square yards (330 square meters) to 700 square yards (585 square meters) per actual production hour in asphalt and about 60% of that in concrete for non ...

Runway grooving significantly improves macro texture and drainage on airfield runways and reduces the risk of hydroplaning, making it easier and safer for pilots to control and brake the aircraft in wet weather. Take a look at the images below to see how effective grooving is.

We have grooved more runways than any other company in the world with over 40,000,000 square yards in the last ten years alone in both asphalt and concrete. Unlike most of our competition, Cardinal's sole focus is the grooving and grinding of airport runways.

Airport Grooving. Grooving is used to increase surface adhesion and prevent aeroplanes aquaplaning on runways by removing surface water. It is believed to be the most cost effective way to increase the co-efficient of friction in the wet whilst improving safety. …

Runway friction is currently highly topical due to the debate over the wish to specify mandatory grooving of the surfacing balanced against the high cost of grooving, reduced expected life and environmental impact of noise created by the grooving process.

As mentioned above, asphalt runways arent ideal to grooving, especially up here in Canada. The airport that I work at in central-western New Hampshire has grooved asphalt runways. One if the bigger drawbacks that I have noticed is that when there has been a large accumulation of ice, it can be difficult to remove, this could be a result of the ...

Pavement groovings, especially transverse pavement groovings, have been used in practice to reduce the occurrences of hydroplaning. This paper presents the development of a three-dimensional finite-volume model to simulate the hydroplaning phenomenon on pavements with and …

Asphalt and concrete surfaces, transversely grooved and ungrooved, were selected for testing since most airport runways use these surface materials. As illustrated in figure 3, both grooved surfaces employed a widely used grooving pattern: 0.63 cm

To address these issues, coupled with a desire to avoid runway grooving, some engineers have revisited the mix design, specification and construction of airport asphalt surfaces. Alternate asphalt mixture types, such as Stone Mastic Asphalt (SMA) and Open Graded Friction Course (OGFC) have also been adopted by some airports [12] .

Nobody grooves runways as quickly and efficiently as Cardinal/International Grooving and Grinding of Conshohocken, Pennsylvania. With over fifty patents in the grooving and related fields, Cardinal is the recognized world leader in airport grooving quality and production.

13. Should it be determined that the primary runway requires grooving, in accordance with Clause 6.09(1)(c), grooves must be perpendicular to the RWY centreline and extended as close as possible to the runway edge, with the exception of: a. Asphalt threshold (THR): Grooving …

Runway surface grooving is often required to provide high skid-resistance for aircraft braking, particularly in wet conditions where hydroplaning must be minimized. An area of potential concern with use of WMA on the surface of airfield runway pavements is the material response to surface grooving. If the asphalt binder in WMA is softer than that of comparable HMA due to reduced binder aging ...

Our Cold Milling Fleet. ABSL Currently owns a large fleet of cold milling machines fully operated and maintained. Cold planning usually removes from 1" to 4" of surface asphalt, but also our equipment allows us to remove up to 12" inches of paving material on a single pass for full roadway reconstruction.
