For security and expansionthroughput of roads on them, a certain marking is applied. And to keep it in any climatic conditions, a special paint is used for road marking, which is selected for the specific climate and road conditions of a particular region.
What is used for markup
Modern road marking is applied withusing 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, differing in chemical composition and technology of application, as well as the length of their service life.
Paint for road marking is a complexmaterial, which contains many components in the form of pigments, fillers, polymers, plasticizers, special additives and solvents. Each of these additives has its own meaning, but in general, their task is to ensure the strength and reliability of the coating. In addition, the composition must comply with environmental regulations.
Features of application
Depending on the application technology, all marking materials are divided into two classes - applied in a cold or hot state.
The first include paints and enamels, the basiswhich are organic solvents, cold plastics and water-dispersion paints. A hot method of marking involves the use of thermoplastic and thermoplastic yellow ribbons, which are glued to the asphalt with a gas burner at a temperature of 5 to 35 degrees.
Cold formulations are recommended for use inmarking out areas of large 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.
Acrylic road acrylic AK-511
This is one of the most popular paints formarking 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 is fully compliant with GOST R 52575-2006, which regulates the use of paints for the treatment of public roads.
Road paint dries quickly, differsa high level of lightfastness and a coefficient of brightness, which serves as a guarantee of the visibility of marking at any time of the day. In addition, it has excellent adhesion, wear resistance, resistance to moisture and various chemical compounds.
Enamel can be used with retroreflectiveglass 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 effect of light reflection is achievedusing in combination with enamel retroreflective elements, which are applied already on top of the paintwork. Advantages of using this composition include:
- conformity of coverage to the requirements of GOST R 52575-2006;
- resistance to external factors;
- rapid application;
- improving the functional properties of road marking.
The average material consumption is 3.5-4 kg / m2 provided that the thickness of the layer is not more than 2.5 mm.
"Technonikol AK" (enamel)
This paint for road marking is a one-component paint material that is applied in a cold way. In its composition - highly disperse pigments and fillers.
"Technikol" does not need to be bred, so itfully ready for use. With its help, it is possible to apply horizontal markings on the roadway, on asphalt concrete and concrete coverings. The paint is supplied in several modifications, specially designed for the scope of application - these can be federal, regional or inter-municipal roads, as well as other roads and sidewalks.
The recommended flowrate of this paint is from 400 g / 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 applying safety lines on asphalt and concrete cover. The set of composition includes retroreflective balls, which provide glow of the marking - the luminance coefficient is 80%. Except white, the enamel can be supplied in yellow, red or black. This paint has the following features:
- You can apply markup to any destination;
- due to high brightness, the markings are visible even in the dark;
- Use enamel on any marking machines;
- high adhesion;
- fast drying.
Widely used and paint for road marking - Indecoat-511. The composition of this coating is a combination of pigments, fillers and targeted additives.
The operation of the applied marking is possible inwide temperature range - from -40 ° to +60 ° С. The production of this paint is carried out using advanced technologies based on imported raw materials, which guarantees its increased wear resistance and whiteness. Use Indecoat-511 can be used for marking concrete and cement coatings.
In the basic version, the paint is available in white, but it is possible to perform in yellow, orange, red and black colors. The single-layer coating accounts for approximately 300-400 g / m².
That the paint of yellow color was well visible andin bright sunlight, and in a dark night, in any weather, special reflective glass microballoons are added to it. They are applied to the paint and refract the light coming from the headlights, reflecting it from a different angle so that it does not get into the eyes of the drivers. Such microspheres are applied in several ways:
- are introduced inside the marking material in a volume of up to 20%;
- sprinkle over the applied marking in the volume of 200-300 g / m²;
- are applied by a combination of both methods.
The dried layer of paint in the markup is approximately 150-300 microns, so the size of the balls should correspond to this value.
Innovative road technologies lead tothe fact that for the marking is used not paint for asphalt, but cold plastic. The use of such a composition is rational due to its high wear resistance and the ability to operate continuously in any climatic conditions. The marking applied by paints will last for a maximum of 2 years, while the service life of cold plastic is much higher.
Not so long ago in our country did not producesimilar materials, and today you can find the compositions of domestic production, but with the use of imported raw materials. We offer an overview of the most popular cold plastics today:
- "Maksidur". It's a white color that hardens on the surface in just 30 minutes. To increase the visibility of marking in the dark and cloudy weather, the coating is supplemented with glass microballoons.
- Technoplast. This material allows you to apply thick-layer markings - 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 used.
Hot method of marking
Marking is a process that requirescareful approach to both materials and technologies. In addition to paints and cold plastic, thermoplastic paints can be used for this purpose. They are attractive due to the increase in the thickness of the applied layer and, consequently, its higher 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 marking is exclusively mechanized. Among the popular thermoplastics we can mention:
- "Marker" is this thermoplastic yellow paintcolor, which is a loose mixture of white color based on petroleum-polymer resins, plasticizers, synthetic rubber and mineral fillers. With the help of this composition, it is possible to apply horizontal road markings on highways that have traffic intensity and high load.
- «Megoplast-Premium». This thermoplastic is used when applying axial marking lines, stop lines and arrows on the road surface. Has a high resistance to temperature changes and abrasion. To apply the material, marking machines are used on a dry surface.
The consumption of thermoplastic for coating thickness of 3-5 mm - 8-10 kg / m².
