Road Marking

Road marking is any kind of device or material that is used on a road surface in order to convey official information. They can also be applied in other facilities used by vehicles to mark parking spaces or designate areas for other uses.
Road markings are used on paved roadways to provide guidance and information to drivers and pedestrians. Uniformity of the markings is an important factor in minimizing confusion and uncertainty about their meaning, and efforts exist to standardize such markings across borders.
Road markings are mechanical, non-mechanical, or temporary. They can be used to delineate traffic lanes, inform motorists and pedestrians or serve as noise generators when run across a road, or attempt to wake a sleeping driver when installed in the shoulders of a road.

It can also indicate regulation for parking and stopping. There is continuous effort to improve the road marking system, and technological breakthroughs include adding retro reflectivity, increasing longevity, and lowering installation cost.

Types of road marking:

Thin & thick layer marking (Type I & II):
Colour, hot or cold plastic etc. are sprinkled with a mixture of small glass beads and antiskid aggregates (type I).
An improved night visibility in the case of wet conditions can be reached with all type II markings: parts of the markings are formed that they protrude from the flat surface of the marking  - and thus also from the water film! The reflection on the surface which cannot be prevented in the case of the type 1 marking in wet conditions is thus at least partially avoided and visibility crucially improved even in rainy conditions.

The type II systems can be presently subdivided as follows:
• Float coat systems with large aggregates
• Agglomerate markings
• Profile markings

In the case of float coat systems with large aggregates, night visibility is achieved through the use of large reflex pearls which protrude from the water film in wet conditions. For thick-layer systems, the reflex pearls are either contained in the marking material or a coarse aggregate is used. Agglomerate markings have key advantages compared to smooth markings: lower risk of slipping, no hydroplaning. In the case of an agglomerate marking, parts of the marking are formed in such a way that they protrude from the water film in the event of rain. Profile markings are particularly well-suited as transverse division lines in tunnels or on roads with alternating 2+1 traffic. The profile marking consists of a 2-3 mm base coat and a 6-7 mm high profile at regular intervals. The driver is warned by the noise development upon driving over this marking, which is caused by the profile.

Temporary tape marking:
The function of temporary road marking ("yellow marking“) is to override the white marking for a temporary period and to indicate modified traffic routing to drivers through this (e.g. in the construction site area). In order to be able to fulfill this function, they have to be at least as visible as the white marking available on site both during the day and at night. Based on experience, many drivers get stressed when construction sites are narrow. Traffic signs must be respected and speed limits adhered to. This situation is amplified even further during darkness and poor weather conditions. With the help of high quality tape marking, the hazard due to poorly visible or even lacking road boundaries can be effectively reduced.

Permanent tape marking:
A crucial advantage of tape marking compared to other types of markings is that it is not created in changing conditions on site (temperature, humidity etc.) but is produced in a controlled way in a modern plant in compliance with the ISO standards. Our permanent tape markings are characterized by ceramic pearls and antiskid particles in a hard polyurethane top coat. This gives the tape marking the highest retroflection and antiskid properties with a long user life.
