Thursday, February 26, 1970.

The filling will be completed to near final levels and allowed

to settle for about six months before the work of constructing the new

runway pavement begins.

The filling between the seawalls on the extension will be

bottom dumped decomposed

formed with layers of different materials

rock; end-tipped decomposed rock; under paved areas, compacted decomposed

rock sub-grade; sand sub-base and asphalt.

The by-pass area and a section of runway at the sea-end of the

extension will have a rigid pavement. Instead of crushed stone and

asphalt, dry lean concrete and reinforced dewelled concrete will be

used to form the top two layers.

Ancillary Works

new approach lights,

Ancillary works include lighting

Strobe lights, taxiway lights, perimeter lights, runway edge lights,

threshold lights and takeoff lights, day markings and fire mains.

Meanwhile, selected stretches of existing pavements are being

grooved for tests to compare skid resistance of the surface to that

of the existing runway's surface.

Should the tests prove satisfactory, the entire runway may be

grooved to improve surface skid, resistance.
