GM1 ADR-DSN.L.520 General – Colour and conspicuity

(a)Where there is insufficient contrast between the marking and the pavement surface, the marking should include an appropriate border.

(1)This border should be white or black;

(2)It is preferable that the risk of uneven friction characteristics on markings be reduced in so far as practicable by the use of a suitable kind of paint; and

(3)Markings should consist of solid areas or a series of longitudinal stripes providing an effect equivalent to the solid areas.

(4)Guidance on reflective materials is given in the ICAO Doc 9157, Aerodrome Design Manual, Part 4, Visual Aids.

(b)At aerodromes where operations take place at night, pavement markings should be made with reflective materials designed to enhance the visibility of the markings.
