Road markings – General

Before permanent reinstatement, temporary road markings may be made using quick drying, durable paint, adhesive strip or like materials of similar colour and dimensions to the original markings.
Road markings removed during the works must be permanently reinstated using materials of equivalent colour and dimensions.
Except where otherwise specified by the authority, the retro-reflectivity and skid resistance of all yellow and white lines must comply with BS EN 1436, as follows:
  1. Dry retro-reflectivity to Table 3:
    • Yellow – Class R0
    • White – Class R2
  2. Wet skid resistance to Table 7:
    • Yellow – Class S1
    • White – Class S3
Unless otherwise agreed by the authority, all white thermoplastic road markings must be treated with surface-applied glass beads to achieve the performance requirements in S11.1.7.
Hot-applied thermoplastic road marking materials with synthetic resin binder must be laid to the following thickness:
  1. Screed lines – 3.5 mm ± 1.5 mm
  2. Sprayed yellow edge lines (No Waiting, etc.) – 0.8 mm minimum
  3. Sprayed lines, other than yellow – 1.5 mm minimum
  4. Extruded lines – 3.0 mm ± 0.5 mm
Cold applied road markings (e.g. methyl methacrylate) may be used as an alternative to hot-applied thermoplastic materials provided that they at least match the appropriate BS EN 1824 durability and BS EN 1436 performance requirements as set out in this section.
The performance requirements for permanent road marking materials must have been established from road trials in accordance with BS EN 1824. The material used to reinstate road markings must be in accordance with Table S11.1.
