Research Report 615 Maintaining the effectiveness of audio tactile profiled roadmarkings for their full life cycle

Published: | Category: Activity management , Research programme , Research & reports | Audience: General

This research considered maintenance of the audio, tactile and visual effects of ATP roadmarkings including for situations where the road surface was to be resealed while the ATP roadmarkings had remaining effective life. The ATP roadmarkings studied are formed with raised ribs of thermoplastic or two-part reactive cold-hardening material laid on a chipseal road surface.

Measurements and observation indicate the audio and tactile effects of the ATP roadmarkings are long-lasting and effectiveness can be retained with resealing ‘in lane’ adjacent to the ATP roadmarkings. Visual effects of ATP roadmarkings need to be considered and maintained separate from the audio and tactile effects. Overall, ATP roadmarkings should be considered an asset and their performance monitored accordingly. The report proposes an approach to monitoring using a subjective rating system.

Keywords: audio tactile profiled (ATP) markings/roadmarkings, chipseal, inverted-profile line markings, maintenance, noticeability, raised-profile markings, reseal, rumble strips, visibility
