The German company RCS · Contracting GmbH offers one of the most technically advanced equipment and vehicle fleet in the world. With economic, environment-friendly systems and more than 35 years’ experience of the management the following services are offered worldwide:

Jetport pavement & runway rehabilitation is a necessity in today’s aviation industry. The continual increase in air traffic necessarily leads to increased tyre rub off on runways. The danger of skidding resulting from slippery runways is familiar to airport safety experts, for this reason friction tests are conducted regularly.

To ensure the highest possible degree of safety during landing, it must become standard practice to remove tyre rubber deposits before the surface reaches the critical limit.

RCS use water without the addition of chemical agents or any abrasive additives. Cleaning with water under high pressure is the least abrasive way to remove rubber deposits and runway markings.

Surface Treatment

→The problems associated with dirty runways are well documented. Rubber and other residues built up, lead to reduced traction (lower friction values). If the friction value falls too low, it is out of the range accepted by the FAA (US Federal Aviation Authority).

The surfaces treated by RCS can be immediately opened to traffic after treatment, i.e. runways can be used completely. Depending on the assignment the following average surface treatment rate achievements can be obtained.

The most important success in stripe removal – pavement or road marking – is to remove the markings from asphalt or concrete without inflicting damage to the surface.

Traditionally, the markings are removed with grinders which use carbide or steel teeth and remove paint to the lowest level, causing grooving damages in average depths of 5 – 10 mm.

The RCS · Contracting system can remove fast and efficiently even the most durable pavement markings (e.g. thermoplastic lines) whether on roads or runways. The RCS system maintains the integrity of the surface and avoids any danger for motorists from grooving damage.

With the RCS system all parameters can be set individually according to the treatment requirements.

THE FOLLWING PARAMETERS TO BE SET: · Working pressure (1,000 – 2,750 bar) · Flow rate (15 – 30 litres per minute) · Speed of the nozzle bar (surface cleaner) · Working speed of the truck (100 – 6,300 m/h) · Distance between nozzles and surface

The highly trained and skilled operators of RCS know how to set these parameters correctly to achieve the best possible line removal results with the lowest possible effect on the treated surface.

The rubber deposits on runways and road markings are re-moved solely by water that is entirely withdrawn by suction along with all residues. On the vehicle, all essential compo-nents are hydraulically driven. The required power is taken by two sources: First, via the direct auxiliary drive system and second, via a gear, which is built into the drive shaft, with a hydrostatic drive. The 1,000 mm Ø surface cleaner (300 mm Ø for line marking removal), located between the first and the second axle, can be lifted up and swivelled back into the chassis within three seconds. In case of an emergency, the vehicle can be driven off the runway within 10 seconds.

The water level in the fresh water tank is monitored continu-ously. If the level reaches the lower point, the operator is warned visually.

If the level drops even further, the system switches auto-matically to the pressureless mode avoiding dry running of the high pressure pump. To ensure that the surface being treated is not damaged, the high pressure system shuts off the moment the driver steps on the clutch or brake.

The high pressure system can only be activated when the vehicle is actually in motion. Even at the full load (2,750 bar and 30 l/min, at a vehicle speed of 4.8 km/h) the water and debris is entirely sucked off the surface and drawn off into the waste water tank.

The ARC·1000® – a further example of our modern techno-logy which more than meets today‘s demands for environ-ment-friendly, innovative and economical products.

RCS Runway Friction Tester, type Mu · Meter FT256, is a continuous surface friction measuring and reporting system for testing airport runways, taxiways and road surfaces. The equipment consists of a small three-wheeled trailer incorporating electronic measuring systems which operate in con-junction with a computer, carried in a special towing vehicle that is equipped with a recommended water tank, water pump and nozzle bar.

RCS operators are trained and skilled to do requested frictiontests as well as full classification runs in accordance with both:

· ICAO FAA Annex 14, Volume 1, Attachment A, Section 7, Para. 7.1 of the International Civil Aviation Organisation Airport Services Manual Part 2 (Third Edition – July 1999).

· Civil Aviation Authority CAP 683, Procedures for Runway Friction Classification & Monitoring.
