Alderney Airport - UK

For more information visit www.asisolutions.co.uk Alderney Airport - UK Alderney Airport is operated by the States of Guernsey. The runway was heavily oxidised and routine FOD sweeps were collecting on average over 400kg each month. The States of Guernsey sought a detailed solution for redeveloping Alderney’s runway. Treatment with RHiNOPHALT® would provide a major improvement in the surface quality of Alderney Airport’s runway, aprons and taxiway for aircraft. Ü Airfield Preservation The fine Rhino-Dust enables immediate The Challenge friction recovery on the treated surfaces. Built in 1935, Alderney Airport was the first airport in the Channel Islands (UK). A line laser was also used for appliying The main runway, 08/26 is 880 m RHiNOPHALT® in smaller areas, and for (2,887 ft) long and is asphalt.

The Solution Using a Findlay Irvine MK2 Grip Tester the 100m section was recorded at 0.93, An application rate of 0.45 litre/m2 was compared to pre-application grip level recommended for all surfaces. This was of 0.83 determined by spraying 1m2 panels at various application rates on the different asphalt surfaces.
