Note   Average means the average of results within a test area, and not results averaged across multiple test areas.

    (2) Tests that satisfy paragraph (1) (b) must be carried out in accordance with ICAO Airport Services Manual, Part 2, Pavement Surface Conditions, triggered by any of the following:

(a) as soon as possible after a newly constructed or overlayed surface is completed;

(b) as soon as possible after the application of a surface treatment or surface enrichment to any part of the runway;

(c) in accordance with a written direction from CASA;

(d) so that not more than 10 years elapses between any 2 tests.

Note   For ICAO documents, see section 1.07.

    (3) Tests that satisfy subparagraph (1) (b) (i) must be carried out as follows:

(a) at intervals along the full length of the runway;

(b) at locations no more than 10% of runway length apart;

(c) at successive test locations on alternating sides of the runway centreline;

(d) at locations offset 4 m from the runway centreline except that the third test location on each side must be 1 m from the runway edge.

       (4) Grooving may be omitted within 100 m of the runway end provided paragraphs (1) (a) and (b) are both satisfied for the sections where grooving is omitted.

       (5) Despite paragraph (1) (b), for an aerodrome used for scheduled international air transport operations, the runway surface friction level must continuously achieve whichever of the following is applicable:

(a) for a new, renewed or reconstructed surface — unless impracticable, at least the preferred friction level specified in column 7 of Table 6.09 (1)-2, applied in accordance with subsection (6);

(b) for the maintenance planning of an existing surface — unless impracticable, at least the preferred friction level specified in column 6 of Table 6.09 (1)-2, applied in accordance with subsection (6);

(c) for any surface where it is impracticable to achieve the level specified in paragraph (a) or (b) — at least the minimum friction level specified in column 5 of Table 6.09 (1)-2, applied in accordance with subsection (6).

Note   Subsection 1.08 (3) relevantly provides that a reference in a Table to a value that is preferred means that, as far as practicable, the use of the value is required in priority to another value expressed in the Table although the other value expressed must be used or observed if the preferred value is not used because it is impracticable to do so. Where the preferred value is not complied with, the aerodrome manual must contain a statement to that effect, the reasons for non-compliance, and the alternative value that is complied with.
