Linemarking means the marking of traffic routes for better orientation purposes and to increase traffic safety.
This is done by putting the marking material onto the pavement using highly developed special machines. This "putting on" method is called application.
Sophisticated roadmarking in particular also demands the greatest possible precision. Identical lines and symbols must always exhibit the same dimensions and distances. It is important to ensure that roadmarking is performed efficiently and economically. This is only possible with semi-automatic or fully automatic marking control systems.
As an independent field within process engineering, the developments for roadmarking are concentrated on the one hundred percent equal distribution of completely different marking materials. This uses perfect cybernetic processes that have been specifically developed for roadmarking.
High quality standards are set for road markings to ensure smooth road traffic, even in poor light conditions. With appropriate road markings, clarity and pathfinding on the road is improved.
This measure usually results in increased safety and thus fewer incidents on the road.

Five Types of Line Markings
There are five possible types of road markings:
The spraying method, the screed box mode, the bonding mode – also called roll coating mode - the spreading mode and the extrusion mode. When speaking of extrudable in roadmarking, this means the pressing of solid to viscous hardenable compounds. (The Latin word "extrudere" means to thrust or drive out.) Here, there are two types of extrudable marking materials: the 2-component cold plastics and thermoplastics.
The scope of the roadmarking to be done will always determine the appropriate machine to be used. Short distances within a town are often completed with hand-controlled machines for roadmarking. Self-propelling ride-on machines are used for roadmarking longer distances outside of town. These machines have the correspondingly large paint and glass bead container capacities and are easy to steer despite their size.
The most demanding league of special machines for sophisticated tasks in roadmarking are roadmarking trucks. The decisive advantage of these machines is that they can be adapted exactly to the requirements of the customer.
A complete motor pool of any specialist includes important additional equipment such as drying and line removal machines as well as melting machineries for thermoplastic materials (also known as heaters).
Drying machines can dry off moist roadways and thus enable safe and qualitatively high grade roadmarking with the most various of marking materials even during unfavorable weather conditions. This saves time and money.
History of Line Marking
Right after the Second World War, as traffic suddenly increased sharply, optimal roadmarking became even more important for the required traffic safety. Today, these experiences are successfully used for roadmarking as well as in air traffic for maneuvering areas and runways.
