6Equipment for the application of pavement marking#
Longitudinal line marking machinery must:
- a) be capable of applying the pavement marking paint or long life material to achieve the required dry film thickness and application of the surface applied anti-skid media and/or glass beads in accordance with the requirements of this Specification
- b) be fitted with automatic pattern control
- c) be capable of applying lines up to and adjacent to traffic islands and kerbing
- d) be capable of marking a set of two lines forming a double one-way or double two-way barrier line concurrently
- e) be capable of accurately applying a continuous line with gaps at specified intervals if required
- f) be capable of accurately superimposing succeeding coats of paint or long life material upon the first coat and/or on existing pavement markings, and
- g) consist of a rubber tyred vehicle which is manoeuvrable to the extent that straight lines can be followed and normal curves can be painted in true arcs.
Where the configuration or location of a longitudinal line cannot be painted with the longitudinal line application machine the pavement marking paint, surface applied glass beads and/or anti-skid media can be applied by hand-sprayed means.
All paint marking vehicles must have an application system to provide coverage of both paint and glass beads that produces similar retroreflectivity in both directions (to within 15%), such as dual angled spray guns and static bead drop systems.
All pavement marking vehicles must have been tested and calibrated to achieve the required rates of application of pavement marking materials.
Stencils, boards and hand-spray equipment must be used to paint transverse markings. Stencils must conform to the dimensions shown on the design documents or be marked in accordance with Queensland MUTCD.
