14Performance criteria#

14.1Dry retroreflectivity#

The Contractor must undertake testing of dry retroreflectivity in accordance with AGPT-T800 and provide certificates for all testing undertaken to the Administrator within 28 days of testing. Record

The Contractor must test the pavement marking at the time periods and frequency specified in Annexure MRTS45.1. If nothing is specified, the time periods and frequency in Annexure B apply.

The minimum values of dry retroreflectivity must comply with the values specified in Annexure MRTS45.1. If nothing is specified, the values in Annexure B apply.

Dry retroreflectivity of white audio tactile lines must be assessed as follows:

1. a)where the audio tactile ribs are placed on top of the longitudinal line, the rib will be measured for retroreflectivity
2. b)where audio tactile ribs are installed adjacent to the longitudinal line, the retroreflectivity of the line and ribs will be measured separately and the line must be assessed in accordance with the requirements in Annexure MRTS45.1. If nothing is specified, the time periods and frequency in Annexure B
3. c)where the audio-tactile ribs are installed without longitudinal line marking, the ribs must be measured for dry retroreflectivity.

The minimum dry retroreflectivity of the audio-tactile ribs must not be less than 150 mcd/lux/m² for the life of the rib.

Wet retroreflectivity#

The wet retroreflectivity of any white pavement marking, when measured in accordance with AGPT-T800 must be a minimum of 80 mcd/lx/m² at any time after application.

Colour#

If requested by the Administrator, the Contractor (at its own cost) must prepare a sample pavement marking material panel in accordance with AS 4049.4 Appendix F.

White markings must be whiter in appearance than the colour ‘Y35 Off White’ as specified in AS 2700.

Yellow markings must be equivalent to ‘Y12 Wattle’ or ‘Y15 Golden Yellow’ as specified in AS 2700, or any colour which falls between these colours.

When non-white colour pavement markings in the wheel path are assessed for colour change against a reference sample in accordance with AS 4049.4 Appendix G, the grey scale rating must be 3 or greater.

Luminance#

When white pavement markings in the wheel path are tested for the luminance factor in accordance with AS 4049.4 Appendix H, Method 2, the test marking must be lighter than Natural Colour System (NCS) swatch S 2500-N (see SS 01 91 02).

If requested by the Administrator, the Contractor must test a sample prepared in accordance with Clause 14.7 in accordance with the equipment and procedure specified in AS 4049.3 Appendix H. The luminance factor must exceed the following when measured in accordance with AS 4049.3 Section 6.1.9:

1. a)80% for white markings, and
2. b)in the range of 45–50% for yellow markings.

Concrete or light coloured aggregate spray seal pavements may reduce the perceived visibility of markings due to the lack of contrast between the luminance of the pavement and the markings. It may be necessary to utilize black or coloured markings in conjunction with or adjacent to white or yellow markings to enhance visibility.

Skid resistance#

The average skid resistance value (SRV) of any pavement marking, excluding audio tactile lines, must be ≥ 45 BPN or equivalent when measured in accordance with AS 4049.4 Appendix J. Skid resistance testing must be undertaken in accordance with the test periods and frequency stated in Annexure MRTS45.1, if any.

The average skid resistance of the beaded base material of an audio tactile line, must be ≥ 45 BPN or equivalent when measured in accordance with AS 4049.2 Appendix L. Skid resistance testing must be undertaken in accordance with the test periods and frequency stated in Annexure MRTS45.1, if any.

Degree of wear#

When pavement markings are tested for the degree of wear in accordance with AS 4049.4 Appendix L, the pavement marking tested must be ‘70% of area intact’ or better, in accordance with AS 4049.4 Appendix M.

Thickness#

Except where specified for tactile purposes, the thickness of (non-profile) pavement marking material must not exceed 5 mm.
