The Light Dome MK8A road stud is installed on every National Primary, Secondary and Motorway throughout Ireland. Repeated tyre action facilitates self cleaning due to the depressible rubber insert. A proven product for over many years – rubber inserts are quick and easy to replace, while the metal castings are suitable for re-use.
TYPICAL USES
The Light Dome MK8A road stud is designed for use on all major roads where a bright durable road/lane delineation product is required. Unlike other embedded road studs, the Light Dome MK8A road stud is suitable for use on bituminous and surface dressed road.
BENEFITS
- Depressible and Self cleaning
- Large footprint reduces traffic stresses transferred to the road pavement
- Snow Ploughable
- A long life embedded road stud; proven performance for many years
- Will facilitate a single layer of surface dressing without any significant reduction in performance (provided tar masks are used)
- Rubber inserts are quick and easy to replace
- Stud castings can be fully cleaned and reconditioned for re-use
INSTALLATION
Using traditional vehicle mounted milling equipment with transverse and depth controls shape an appropriate slot in the carriageway.
Dispense sufficient stud grout adhesive at the recommended temperature for the stud to be placed evenly. Install the Light Dome MK8A road stud housing at the correct level into the carriageway. Carefully pour more adhesive material around the outside of the housing to seal the edges completely in the recess.
The road can be opened to traffic as soon as the adhesive has set.
