The variety of pavement marking materials and products available to the traffic engineer today is vast and continues to grow! This is the challenge facing Brisbane City Council (BCC) today. With over 5,400 kilometres of sealed road, ranging from residential cul-de-sacs to major arterials, the choice of pavement marking material is critical to ensure longevity of the product and value for money for Council whilst maintaining safe and clear guidance to the road user. BCC has established two pavement marking test decks containing in excess of twenty-two different products or materials. The decks contain samples of the four major types of pavement marking materials cold-applied plastics, waterborne paint, thermoplastics and linemarking tapes. The materials are used in combination with glass beads and anti-skid material. The trial also includes examples of raised retro-reflective pavement markers and adhesives. Since being established in August 2005, the decks have been tested on a regular three monthly basis for visual signs of wear, retro-reflectivity and skid resistance. We wish to share these results and revised processes as examples of an applied engineering techniques addressing practical implementation issues.
