Runway, Taxiway and Apron Pavement, Year 2040
Aprons
Cement concrete will be used in the con- struction of apron areas. With the possibility of oil spillage on aprons, where refuelling and minor maintenance takes place, the use of asphaltic conereje could lead to rapid deterioration of the apron surface. The con- crete will be laid in panels, to minimize crack- ing due to movements induced either by settlement of the underlying reclamation or by changes in temperature.
Aircraft guidance fighting and marking will be provided and the aprons will be floodlit to permit night operations. Fuel will be delivered to the aircraft via underground fuelling facilities, with fire hydrants, clectri- cal power supply and other necessary ser- vice utilities being provided close to the
aircraft stands.
Infrastructure
Airside Roads
0 300 600 900 m
Access to aircraft and the runways and taxiways will be provided by a network of airside roads. Many of them will be delineated by marking the aprons, but the remainder will be of flexible construction, generally 7.5m wide. Perimeter roads will also be of flexible construction and will be
4m wide. To permit rapid deployment of fire service vehicles, special egress roads will lead from the fire stations to the runways.
Vehicular Service Tunnels
There is a requirement for large numbers of vehicle movements between the cargo
terminal and the catering facilities, located south of the runways, and the passenger terminals located between the runways.
These movements will occur via two tun-
nels beneath the southern runway.
Each tunnel will be approximately 800m long and will contain dual two-lane car riageways at a maximum gradient of 5% and separate services tunnels. Each tunnel will be provided with longitudinal ventila- tion. lighting, signage and firefighting equipment. Drainage will be via a sump from which water will be pumped into the
sewerage system.
Landside Roads and Railway Reserve
The landside roads which provide access to cach of the facilities are shown on the Air- port Layout Plan. They will be designed to territory standards and will be provided with lighting, signage, fire hydrant's and bar- riers, and will be constructed with a flexible
bituminous running surface.
Structures for the grade separated inter- changes will be comprised of pre-stressed concrete decks supported by reinforced concrete columns, which will in turn be sup- ported by reinforced concrete caissons or spread-footing foundations.
The railway reserve, located adjacent to the North Lantau Expressway, will pass under
the road in a tunnel near the end of the
southern runway. The tunnel will be con- structed of reinforced concrete by the cut- and-cover technique, and will be provided with a smoke extraction ventilation system and firefighting hydrants. It will be drained by pumps which will discharge into the sur face drainage system.
Marine Structures
A ferry complex will be located at the east- ern end of the airport. The full range of ferry services to be provided is yet to be determined, however, initial provision will be made for a domestic ferry service. probably connecting with Tuen Mun.
This facility will be a single pier, with a berth
cach side and with two levels to cater for
double decked conventional Hong Kong ferries. Other piers may be added later. either to accommodate different types of
