When we talk about road studs, we are mainly referring to road studs for highway use. It is also called raised road marking. It is a kind of traffic safety facilities. It is mainly installed in the middle of the road marking or the middle of the double yellow line, through its retro-reflective properties to remind drivers to drive according to the lane. There are several types of road studs, each with its own advantages and disadvantages. Proper installation and maintenance of road studs is essential to ensure their effectiveness. Here are some guidelines for installing and maintaining road studs:
Chapter 1 The Types of Road Studs
There are several types of road studs to choose from, according to the material of aluminum road studs, plastic road studs, ceramic road studs, solar stud sa kalsadas; according to the color points are white, red, yellow, green and so on. Each type of road studs have their own advantages and disadvantages, take the solar road studs, the advantage is that it can be self-luminous, without the need to lay cables, energy saving and environmental protection; but it is costly, need to be cleaned and maintained, if the solar panels are covered with dust and spoils, it will affect the performance of its luminescence. Therefore, when choosing road stud products, should consider the road situation, the road environment assessment, and then choose to install which kind of road stud lights.
Chapter 2 Road Stud Installation
- Preparation tools and materials: road studs, drilling tools, epoxy adhesive or asphalt adhesive, wrenches or screwdrivers, markers or chalk used to mark the location, tape measure, safety equipment
- Installation steps:Installation is divided into the following steps: marking the location, drilling, cleaning the holes, applying adhesive, placing the road studs, adjusting the alignment, cleaning up the excess adhesive, curing, testing, for more details, you can see the previous article point 3
- Common Problems During Installation
A list of common problems in the installation process:
- Installs road studs on rough surfaces. This phenomenon will directly lead to the unbalanced force on all parts of the road stud, and it will be easily damaged after being run over by a large-tonnage vehicle.
- Road studs are installed in poor condition. The firmness of the road studs depends on the road studs, glue and road surface of the three between the degree of precision, more dirty installation site dust will absorb most of the adhesive force of the glue, so that the road studs and road surface bonding force is not stable, easy to fall off.
- Installation glue is applied too much or too little. Applying too little glue will directly reduce the firmness and service life of the road studs; applying too much glue will cause the glue to ooze out and spread to the reflector, affecting the brightness of the reflector.
- Installation glue is not evenly applied. In addition to applying the right amount of glue, the operation of applying glue should also be uniform to ensure the balance of the force applied to the various parts of the road studs, to avoid damage to the road studs due to the imbalance of the force.
- Glue curing time is not enough, the installation of new road studs generally need 6 – 8 hours to fully cured and fixed on the road surface, in many cases people tend to install less than 2 hours to remove the isolation facilities, so that when the road studs by the vehicle crushed or impact will occur deformation, dislodgement.
And the following practices can effectively avoid the occurrence of the above problems:
- In place the installation of isolation facilities, determine the installation location and ensure that the installation road is level.
- Clean the installation position with a brush, and at the same time ensure that the installation position is dry;
- Apply the appropriate amount of glue evenly on the road studs;
- Press the road stud firmly onto the installation position to ensure the correct direction and to remove excess glue;
- Check the road studs within 2 hours after installation to ensure that they are not incorrectly installed, bent or pressed out of shape.
- Road studs need to be installed after the completion of 6-8 hours or more to remove the installation of isolation facilities.
Chapter 3 Road Stud Maintenance
Road stud maintenance involves a number of aspects, the first is a regular inspection and special inspections to ensure that day and night are monitoring the road studs and record the results.
Regular inspection at least once a week, and encountered typhoons, rainstorms, holidays, line anomalies, fault tripping and other situations require special inspections, general safety hazards should be dealt with within 24 hours and recorded, special safety hazards need to be reported immediately and take measures to solve. At the same time, the weekly road stud monitoring system, equipment, distribution room (box), tools and the environment for cleaning, and regularly brush anti-rust paint to prevent rusting road studs.
In accordance with the road studs facilities maintenance requirements overhaul, should be a comprehensive inspection of lamps, light source electrical appliances, cables and other equipment, the use of temporary power cords connected to the light panel on the power plug energized overhaul needs to be added to ensure the safety of electric shock protector. In the process of putting away the wire rope, should check the appearance of the wire rope, pay attention to whether there is no overlap, distortion, corrosion, fracture, serious stress and so on, check whether the sliding parts are flexible and reliable. For the damaged road studs, light source electrical appliances, cables, etc. need to be replaced in a timely manner, check whether the fixed bolts are loose, firm, safe and reliable, whether the positioning pins, automatic hooks are flexible and reliable, and serious corrosion of the parts should be replaced. Fixed at the bottom of the road studs of the motor, gearbox and other transmission mechanism should be as airtight as possible to cover, to prevent the coil from moisture leading to insulation damage, check whether the oil in the gearbox is sufficient, whether the oil is blackened or contains impurities, the activity of the motor transmission mechanism should be placed in a dry place, and before running with a vibrator to test its insulation resistance (not less than 1MΩ).
The control electrical appliances in the control circuit such as AC contactors, thermal relays, travel switches and command controllers need to be thoroughly inspected before operation, and the electrical components should be replaced if they are found to be faulty. Before the rainy season comes every year, the grounding protection device and lightning protection device of the road lighting facilities need to be inspected and the grounding resistance tested, if the grounding resistance fails to meet the corresponding requirements (less than 10Ω), it should be dealt with in time. All the maintenance contents need to be recorded in detail in the book for subsequent tracking and management to ensure the long-term stability and safety of road stud facilities.

Proper installation and maintenance of road studs is critical to ensuring road safety. The effectiveness and durability of road studs can be ensured by choosing the right type of road stud, following installation guidelines, and performing regular inspections and maintenance. These measures help to maintain clear lane markings and improve overall road safety.
