The impact of insufficient glass bead scattering during road hot-melt marking construction

In modern traffic management, the setting of road markings is one of the important measures to ensure driving safety and improve traffic efficiency. Especially at night or in adverse weather conditions, the visibility of markings is particularly critical. Glass beads, as an important material used to enhance the reflective performance of road markings during construction, have a direct impact on the quality and effectiveness of the markings due to the amount of scattering during the construction process. TOP ROAD road marking paint manufacturers will conduct in-depth discussions on the consequences of insufficient glass bead scattering during road marking construction.
1、 The role and importance of glass beads
The main function of glass beads during road marking construction is to increase the reflectivity of the markings. Glass beads reflect light from car lights, making road markings more prominent at night or in low visibility conditions, thereby reducing the risk of traffic accidents. The transparency of glass beads can effectively improve the recognition of drivers, enabling them to better judge the direction and speed of travel during the driving process.

1.1 Physical properties of glass beads

Glass beads are small and round optical materials, usually made of colorless or colored glass, with good reflective properties and high wear resistance. The diameter, density, and coating of glass beads can vary according to different needs. Sprinkle an appropriate amount of glass beads on the surface of the marking paint to create a reflective effect when the marking is exposed to light. This reflective principle is an important foundation for achieving safe driving.
1.2 Classification and Application of Markings
Road markings are divided into solid and dashed lines, and different markings have different meanings, covering lane separation, parking instructions, direction guidance, etc. The visibility of road markings directly affects the smoothness and safety of traffic flow in different road sections and situations. If the scattered glass beads are insufficient, it may cause the marking to fail to achieve the expected reflective effect, resulting in serious traffic hazards.
2、 The consequences of insufficient dissemination of glass beads
2.1 Decreased visibility
Insufficient scattering of glass beads can make road markings almost unrecognizable to drivers in low light conditions. This issue is particularly prominent during nighttime, rainy or foggy weather conditions. Drivers are prone to making misjudgments when they cannot clearly see the markings, which can affect driving safety. When vehicles are driving at high speeds and cannot recognize markings in a timely manner, the probability of traffic accidents significantly increases.
2.2 Impact on Traffic Flow
One of the main functions of road markings is to guide the direction of vehicle travel. If the markings are blurred due to insufficient glass bead scattering, it is easy to cause traffic congestion. Especially at complex road sections such as intersections and roundabouts, vehicles may repeatedly change lanes due to unclear visibility, increasing the risk of traffic conflicts and affecting the overall road capacity.

2.3 Increase the incidence of accidents

According to road traffic safety research, when the visibility of markings decreases, the probability of vehicles from different directions colliding at intersections significantly increases. The summary data shows that a certain proportion of traffic accidents are caused by the loss of reflective effect of markings, and insufficient scattering of glass beads is one of the main reasons. Therefore, the appropriate amount of glass bead scattering not only affects the visual effect of the marking, but also directly relates to the serious issue of life safety.
2.4 Increase post maintenance costs
The construction of road markings is a systematic project, and the quality is guaranteed during the construction process. If the poor marking effect is caused by too few scattered glass beads, the relevant departments will have to carry out additional maintenance and inspection. This not only wastes manpower and material resources, but also increases the economic burden. For example, the additional costs incurred by the construction unit for repainting markings and supplementing glass beads will affect the city’s transportation budget.
In summary, the importance of glass beads in road marking construction cannot be ignored. Insufficient sowing amount not only leads to poor reflective effect of markings, thereby affecting driving safety, but also has a negative impact on overall traffic flow. To ensure traffic safety, relevant units must attach importance to construction standards and process control, ensuring that every marking can play its due role.
