1. What Are Road Studs?
Road spikes - commonly called road studs or pavement markers - are metal or composite fixtures used in the laying and maintenance of road traffic facilities. Their main function is to mark lane boundaries, edge lines, curves and hazard zones, and to reflect vehicle headlights at night, helping drivers maintain lane discipline and reducing the risk of accidents. Road studs must withstand repeated tyre loading, water, de-icing chemicals and temperature cycles, so both the stud body and the fixing system must be selected for the specific pavement type and traffic class.
2. Method A - Direct Ground Fixing (Retrofit Installation)
The direct ground-fixing method is used to install road studs on existing asphalt or cement pavement. The operation steps are as follows:
- Use a drill or other suitable tool to make a round hole with a diameter matching the stud base and a depth of 5-10 cm at the fixing position.
- Apply a pavement-grade adhesive (epoxy or bitumen-based compound) to the base of the stud, insert it into the hole, and drive it firmly with a hammer or installation tool until it is level with the road surface.
- Clean any excess adhesive from the surrounding surface and allow the recommended curing time before opening the lane to traffic.
- Notes: choose an adhesive rated for the pavement temperature range; do not install in wet or frost conditions; protect the freshly installed stud with temporary traffic control until the adhesive has fully cured.
3. Method B - Installation Base Method (Installation During Paving)
The installation base method fixes the road stud through a base plate and is suitable for installing studs at the same time as paving the road surface. The operation steps are as follows:
- Before the road surface is paved, drill a hole with a diameter matching the stud and a depth of 10-15 cm at the location where the stud is to be installed.
- Place the stud into the hole with the top exposed above the ground, and fix the stud with the installation base at the bottom of the stud.
- Finally, place the sign or roadblock to be installed on top of the stud.
Notes: ensure the base is level and fully embedded so the stud top sits flush with the final wearing course; verify verticality before the surrounding material sets.
4. Method Selection Guide
| Condition | Recommended method |
|---|---|
| Existing asphalt or concrete pavement | Direct ground fixing with adhesive |
| New road construction / resurfacing | Installation base method during paving |
| High-speed or heavy-traffic lanes | Base plate + mechanical anchorage for higher pull-out resistance |
| Temporary worksites | Removable studs with adhesive pads or magnetic bases |
5. Maintenance and Safety
- Inspect studs periodically; replace damaged, faded or missing units immediately.
- Keep adhesive storage and application within the manufacturer's temperature limits.
- Follow local traffic-management regulations during installation, curing and replacement work.

The appropriate road spike installation method depends on the road surface, load conditions, and application requirements. Direct fixing provides a simple installation method, while base plate mounting offers additional stability where required. GNEE RAILWAY RAILWAYL supplies road spikes and related fastening components for different installation conditions.
