To ensure safety and increase the capacity of roads, certain markings are applied to them. And so that it remains in all climatic conditions, a special paint is used for road marking, which is selected according to the climate and road conditions of a particular region.
What is used for markup
Modern road marking is applied using special resistant paints, thermoplastics, spray plastics, thermoplastic tapes and cold plastics. All this meets the requirements of GOST, but in most cases, special enamels are used, which differ in chemical composition and application technology, as well as in terms of service life.
Road marking paint is a complex material that contains many components in the form of pigments, fillers, polymers, plasticizers, special additives and solvents. Each of these additives has its own significance, but in general, their task is to ensure the strength and reliability of the coating. In addition, the composition must comply with environmental standards.
Application Features
Depending on the application technology, all marking materials are divided into two classes - applied in cold or hot condition.
The first include paints and enamels, which are based on organic solvents, cold plastics and water-dispersion paints. The hot marking method involves the use of thermoplastics and yellow thermoplastic tapes, which are glued to the asphalt with a gas burner at a temperature of 5 to 35 degrees.
It is recommended to use cold formulations when marking areas of high wear, for example, at pedestrian crossings. Such plastics will last about two years. And if the movement is more intense, it is required to use those materials that are applied by the hot method.
Enamel acrylic road AK-511
This is one of the most popular paints for marking the roadway and streets. The coating can be operated in a temperate continental climate. The paint itself consists of pigments and fillers in combination with various modifying additives. This composition fully complies with GOST R 52575-2006, which regulates the use of paints for the treatment of public roads.
Road paint dries quickly, has a high level of light fastness and a brightness coefficient, which serves as a guarantee of the visibility of the marking at any time of the day. In addition, it has excellent adhesion, wear resistance, resistance to moisture and various chemical compositions.
Enamel can be used with retroreflective glass beads, which increases the reflective properties of the coating. Road paint is applied to a dry and clean surface; if necessary, it can be diluted with a solvent.
The greatest light reflecting effect is achieved by using reflective elements in combination with enamel, which are already applied over the paintwork. The advantages of using this composition include:
- compliance of the coating with the requirements of GOST GOST R 52575-2006;
- resistance to external factors;
- fast application;
- improving the functional properties of road markings.
The average material consumption is 3.5-4 kg / m 2 , provided that the layer thickness is not more than 2.5 mm.
TechnoNIKOL AK (enamel)
This road marking paint is a one-component cold-applied paint material. It contains highly dispersed pigments and fillers.
Technikol does not need to be bred, so it is completely ready for use. With its help, you can apply horizontal markings on the roadway, on asphalt concrete and concrete pavement. The paint is supplied in several modifications specifically designed for the scope of application - it can be roads of federal, regional or intermunicipal significance, as well as other roads and sidewalks.
The recommended consumption of this paint is from 400g / m² to 700 g / m², depending on what type of substrate.
Enamel AC-5307 "Line"
This paint for road marking is white. It is used when drawing safety lines on asphalt and concrete pavement. The kit includes retroreflective balls that provide a luminescence marking - the brightness coefficient is 80%. In addition to white, enamel can be supplied in yellow, red or black. This paint has the following features:
- you can mark up any purpose;
- due to the high brightness, the marking is visible even in the dark;
- Enamel can be used on any marking machines;
- high adhesion;
- quick drying.
Indecoat-511
Widely used and paint for road marking - Indecoat-511. In composition, this coating is a combination of pigments, fillers and targeted additives.
Operation of the applied marking is possible in a wide temperature range - from -40 ° to +60 ° C. The production of this paint is carried out according to advanced technologies based on imported raw materials, which guarantees its increased wear resistance and whiteness. You can use Indecoat-511 for marking concrete and cement coatings.
In the basic version, the paint is available in white, but it can be made in yellow, orange, red and black. A single-layer coating accounts for approximately 300-400 g / m².
Retroreflective materials
In order for the yellow paint to be clearly visible in bright sunlight and dark at night, in any weather, special reflective glass beads are added to it. They are applied to the paintwork and refract the light coming from the headlights, reflecting it at a different angle so that it does not get into the eyes of the drivers. Such beads are applied in several ways:
- are introduced into the marking material in an amount up to 20%;
- sprinkled over the applied marking in a volume of 200-300 g / m²;
- applied by a combination of both methods.
The dried paint layer in the markup is approximately 150-300 microns, so the size of the balls should correspond to this value.
Cold plastic
Innovative road technologies also lead to the fact that, for marking, not cold asphalt paint is used. The use of such a composition is rational due to the high wear resistance and the ability to long-term operation in any climatic conditions. The marking applied with paints will last a maximum of 2 years, while the service life of cold plastic is significantly higher.
Not so long ago, similar materials were not produced in our country, and today you can find compositions of domestic production, but using imported raw materials. We offer an overview of the most popular cold plastics today:
- "Maksidur." This is a white compound that hardens on the surface in literally 30 minutes. To increase the visibility of the markings in the dark and cloudy weather, the coating is complemented by glass beads.
- Technoplast. This material allows you to apply thick-layer marking - stop lines, noise lines, pedestrian crossings, direction arrows and much more. The distinctive features of this plastic include high wear resistance, a variety of color solutions, the possibility of adding glass beads.
With a coating thickness of 2 mm, an average of 3.5-4.0 kg / m² of material is consumed.
Hot marking method
Marking is a process that requires a careful approach to both materials and technologies. In addition to paints and cold plastic, thermoplastic paints and varnishes can be used for this purpose. They are attractive because of the increased thickness of the applied layer and, consequently, their longer service life. On the other hand, thermoplastics are more expensive, so they are used mainly in areas where the wear rate is very high. Such markings are applied exclusively mechanically. Among the popular thermoplastics can be noted:
- "Marker" - this yellow thermoplastic paint, which is a loose mixture of white on the basis of petroleum resin, plasticizers, synthetic rubber and mineral fillers. With this composition, you can apply horizontal road markings on roads that have traffic density and high load.
- "Megoplast-Premium." This thermoplastic is used when applying axial marking lines, stop lines and arrows on the road surface. It is highly resistant to temperature extremes and abrasion. For applying the material, marking machines are used on a dry surface.
The consumption of thermoplastic for a coating with a thickness of 3-5 mm is 8-10 kg / m².
