The Light Dome MK100A road stud is a new type of depressible road stud. It consists of a circular metal casting and a unique design of depressible rubber insert. Repeated tyre action facilitates self cleaning due to the depressible rubber insert. The technology used to develop this product has been used for over many years on other types of embedded depressible road studs. The rubber inserts are quick and easy to replace, while the metal castings are suitable for re-use.
TYPICAL USES
The Light Dome MK100A 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 MK100A road stud is suitable for use on bituminous and surface dressed road.
BENEFITS
- Depressible and Self cleaning
- 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
- Quick as easy to install
- 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.
