【Drum Method】Test for Surface Damage and Retroreflectivity Decay of Glass Beads It’s very difficult to evaluate the durability of road markings on site owing to being too many factors that could cause impact on it. Many researchers have been trying to find a suitable attenuation model that can predict its retroreflectivity A known alternative to on-site assessment is the use of turntables where, u...

The Relationship Between the Embedment Depth of Glass Beads and the Retroreflectivity of Road Markings Bead Embedment Depth: The depth to the embedment of glass beads can be assessed by close-up visual inspection. Beads should be embedded into the pavement marking material at 60 percent of the bead diameter for maximum retroreflective performance. For the material that is "behind" the bead is the ...

The Harm of Unclear Road Markings Road accidents are one of the leading causes of death in the world. According to statistics，25,047 people died on EU roads in 2018 alone. It is estimated that about $2 billion is spent annually on road marking in the United States only. Road safety is improving in most European countries, but progress remains slow and far from the targets set. Progress is slow in ...
