In the daily travel, we can often see the road studs, they are like loyal guards, in the guidance of the traffic, to protect the road safety plays an important role. However, in recent years, many places have been removed from the phenomenon of road studs, which hides the reason behind what? Next, let us find out.
Road studs, although small, but shoulder many important mission. In the indication of the direction of the road, whether it is a straight road or a curved road, road studs can be arranged through their own, clear for the driver to indicate the route forward. In lane delineation, different colors and shapes of road studs, clearly distinguish between different lanes, to prevent vehicles from changing lanes at will, to maintain traffic order. At the same time, at night or in bad weather, the reflective properties of road studs can attract the attention of drivers, play an effective role in warning and reduce traffic accidents.
With the rapid development of science and technology, road construction is also constantly innovating. In new road projects, some new technologies are beginning to emerge. For example, intelligent road lighting systems not only provide more adequate and smarter lighting, but also realize the regulation of traffic flow through intelligent interaction with vehicles, which is far more functional than traditional road studs. In addition, the emergence of new marking materials, such as hot melt marking with super reflective properties and durability, can clearly display lane information in a variety of environments, gradually replacing some of the functions of road studs.
At the same time, road widening, re-planning layout and other projects will also lead to the location of road studs and new design conflicts. When a road is widened, the existing pins may no longer be in the appropriate lane boundaries, making them ineffective and potentially misleading to drivers.
The impact of climate and environment on roadway studs should not be underestimated. In extremely cold regions, road studs undergo frequent freeze-thaw cycles due to drastic temperature changes. During the day, the temperature rises, the moisture around the stud melts, and at night the temperature plummets, the moisture freezes and expands, and this repetitive process easily loosens and damages the stud. In rainy areas, continuous rainfall will gradually lose the fixing material around the studs, leading to loosening of the studs. Moreover, in the waterlogged road surface, the reflective effect of the road stud is greatly reduced, and can not effectively play a warning role.
Road studs are exposed to the outdoors for a long time, subjected to the wind and sun, the repeated crushing of vehicles. For solar road studs, its solar panels are exposed to ultraviolet radiation for a long time, will gradually aging, the efficiency of solar energy conversion is reduced, which in turn affects the luminous effect of LED lights. At the same time, the LED light itself also has a certain service life, with the increase in the use of time, the brightness will gradually weaken, can not clearly indicate the road. In addition, the shell of the stud in the long-term mechanical wear and tear, there may be rupture, deformation and so on, affecting its overall performance.
Traffic accidents are also an important cause of damage to road studs. When the vehicle collided with the stud, the huge impact will make the stud instant deformation, displacement or even broken. These damaged road studs not only can not continue to perform its instructions and warnings, but also become an obstacle on the road, bringing safety hazards to the subsequent vehicle driving.
Road studs were originally designed to ensure traffic safety, but when they fail, they can cause damage to vehicles instead. Road studs usually have sharp edges, so if a tire accidentally runs over a loose or damaged stud while the vehicle is in motion, it can easily be scratched, resulting in air leakage or even a flat tire. In addition, loose studs in the vehicle driving under the action of airflow, may be involved in the vehicle chassis, damage to the vehicle's suspension, brakes and other key components.
Damaged studs protruding on the road are a great threat to vehicles traveling at high speeds. Once the vehicle is crushed into such a stud, it is likely to instantly burst the tire, resulting in the vehicle out of control, causing serious traffic accidents. At night, unlit road studs cannot provide drivers with accurate road information, and drivers may deviate from the normal driving route due to errors in judgment, increasing the probability of accidents.
Due to the harsh environment in which roadway studs are located, the damage rate is relatively high. In order to ensure their normal operation, regular inspections and repairs are required. This requires a lot of manpower, maintenance personnel need to check the condition of the road stud along the road section by section. At the same time, it is also necessary to equip the corresponding transportation and inspection equipment, all of which increase the cost of material resources. Moreover, once the stud is found to be damaged, it needs to be repaired in time, which further increases the financial investment.
For solar road stud, its core components such as solar panels, batteries, etc., the replacement cost is high. Solar panels are relatively expensive, and the replacement process requires professional technicians to operate, which in turn increases labor costs. Battery as an energy storage device, with the growth of the use of time, the performance will gradually decline, the need for regular replacement, which has also become a considerable expenditure. Taken together, the overall cost-effective maintenance of the stud is low.
Transportation departments will formulate new regulations out of consideration for traffic safety, environmental protection and many other factors. For example, some types of road studs in the production process may use some environmentally harmful materials, with the improvement of environmental requirements, these road studs may be restricted or prohibited. In addition, from the point of view of traffic safety, the new regulations may put forward higher standards for road markings and safety facilities, and some non-compliant road studs will face the fate of being removed.
In the construction of cities, urban planning policies are also being adjusted. Nowadays, many cities pursue a more beautiful and smooth road surface effect to enhance the city image. Road studs are gradually removed because they protrude from the road surface and may affect the overall smoothness and aesthetics of the road surface, which is not in line with the new concept of urban planning.
As technology advances, new road marking technologies continue to emerge. Reflective marking has been widely used in recent years, which is made of special reflective materials that can reflect vehicle lights at night or in low light conditions, clearly showing lane boundaries and road contours. Intelligent road marking system even integrates advanced sensors, communication technology, etc., which can adjust the marking information in real time according to the traffic flow, weather conditions, etc., and provide drivers with more accurate and comprehensive road guidance.
In addition to the new road marking technology, there are some other traffic safety facilities that have also replaced the function of road studs to a certain extent. Roadside warning lights can draw the attention of drivers at night or in inclement weather through flashing lights, and play a warning role. Electronic guidance screens can display a variety of traffic information, such as road conditions ahead, speed limits, etc., to provide drivers with more information to help them better plan their driving routes.
Thorough preparation is key before embarking on the removal of damaged studs. First, you need to carefully inspect the damage to the cat's-eye road reflectors (i.e., the studs) to confirm the need for replacements, identifying the location of the studs and the number of studs that need to be replaced. This step provides clear direction for subsequent work and avoids blind operations.
Next, prepare the tools needed to replace the solar studs. The types of tools include, but are not limited to, cutters, power hammers, chisels, glue guns, and so on. These tools will play an important role in the removal and installation process, and different tools are suitable for different work scenarios to ensure smooth construction. At the same time, prepare brand new solar studs, installation materials and safety signs. Safety signs are crucial in the entire replacement process, and setting up a construction cordon can effectively protect the safety of construction workers and passing vehicles, and prevent accidents from occurring.
When removing old road studs, first cut or chisel away the damaged studs along with the residual adhesive using a cutter or an electric hammer. Take extra care to ensure that the surface of the ground is clean and free of residue after the stud has been removed. If the old studs have already fallen off by themselves, it is also important to thoroughly remove the original adhesive or debris to ensure that the construction surface is level. Because the uneven surface will affect the installation of the new solar studs, and may even lead to the installation of the new studs are not strong.
After removing the old studs and cleaning up any residue, sweep the floor with a broom to remove any dust or debris and ensure that the construction area is clean and dry. This is to allow the new stud to adhere firmly to the ground. If the road surface is wet at the time of construction, you can use a hair dryer or dryer to dry the treatment, to create good conditions for the installation of new pins.
According to the stud installation specifications, the bottom of the new stud evenly coated with epoxy resin glue. The amount of glue should be moderate, too little to ensure that the stud and the ground firmly affixed, too much may overflow, affecting the appearance and waste. Place the new stud in the designated location, gently compacted, so that the bottom of the stud and the road surface in close contact. At this point, you need to carefully check whether the orientation of the solar road studs is correct, to ensure that the reflective surface is facing the direction of vehicle travel, so as to maximize the warning effect of the road studs. Once the installation is complete, apply moderate pressure to the stud and let it sit for a few minutes to allow the adhesive to initially set.
The curing time of the stud usually takes more than 2 to 4 hours, during which time it is important to ensure that the adhesive is fully cured. When curing is complete, remove any excess adhesive and check for any missing or loose studs. Only after confirming that all studs are securely installed can the construction warning signs be removed and the roadway restored to normal traffic. This not only ensures the installation quality of the new stud, but also ensures the safety of the road.
In summary, the removal of roadway studs is the result of a combination of factors. Changes in road conditions, damage to the stud itself, consideration of safety hazards, the pressure of maintenance costs, the guidance of regulations and policies, and the emergence of alternatives, have prompted the relevant departments to adjust the road stud. In the future, with the continuous development of science and technology, we have reason to expect the emergence of more advanced, safe, environmentally friendly road safety facilities, to provide more reliable protection for people's travel. At the same time, it also reminds us that in the process of road construction and maintenance, we should continue to explore and apply new technologies to meet the needs of traffic development and create a safer and more efficient road traffic environment.
