Are Higher-Performing Road Markings a Cost-Effective Investment in Safety? Road markings play an important role in road safety and optimizing the use of road space. They help provide information that cannot be easily conveyed using mounted signs. Moreover, signage applied directly to the road surface offers a form of continuous messaging which can be observed when a verge-mounted sign is concealed...

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 ...

【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...

History of Glass Beads for Road Markings Glass beads have always been used to make reflective road signs. If properly embedded in the marking material, the glass beads are able to collect the incident light and reflect some of it back to the light source. It's this ability that makes these small, spherical glass particles unique. 1952: Pocock and Rhodes first studied the principle of glass ...

Influence of Construction Temperature on Hot-Melt Markings The construction temperature of hot-melt marking paint generally refers to the temperature of the marking car hopper, which usually requires that the material in the hopper should be maintained at 180-220 ° C. When the melt temperature of hot melt marking paint is too high, the volatilization of additives in the paint is accelerated. At th...
