Materials for road markings

Today, markings on the road are applied different materials. These include paints, cold plastics, polymer tapes, thermoplastic, etc.
Paints are much cheaper than other materials, which makes them very popular. Moreover, not only the material itself is cheaper, but also the technology for its application. This material dries quickly. Complex marking elements can be easily applied using a stencil. But, in addition to all the advantages, there is one significant drawback– rapid wear of this material on horizontal markings.

Thermoplastic, like paint, is a very popular material for road markings. Its peculiarity is that application requires a special device for infrared heating of the asphalt coating. This material does not require solvents. Application occurs when thermoplastic is heated to 150-220 degrees Celsius. This material is much more durable than paint.

Cold plastics can act as a replacement for thermoplastics. This road marking material does not require heating. In its original form, it is liquid and comes complete with a hardener. Cold plastics may be the optimal type for horizontal road markings, but their widespread use is limited by their relatively high cost.

Another type of road marking material is polymer tape. This material can be classified as durable. Its main drawback is strict adherence to application technology, which is not always possible to achieve in different climatic conditions.

When choosing the type of materials for marking, it is important to take them into account specifications. It is very important that the markings are clearly visible at any time of the day. During the day, visibility is affected by the size and brightness of markings. At night, visibility is influenced by reflective properties. To give the markings retroreflective properties, glass beads are added to the plastic, which ensures that the headlight light is reflected from the road surface with the markings applied. However, they cannot provide 100% sufficient visibility.
Artificial lighting plays a big role in the visibility of markings.

To ensure safety and expand the capacity of roads, certain markings are applied to them. And in order for it to be preserved in any climatic conditions, a special one is used, which is selected for the characteristics of the climate and the condition of the roads of a particular region.

What is used for marking

Modern road markings applied using special durable paints, thermoplastics, spray plastics, thermoplastic tapes and cold plastics. All this meets the requirements of GOST, but in most cases special enamels are used that differ from each other chemical composition and application technology, as well as 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 - those applied in a cold or hot state.

The first include paints and enamels, which are based on organic solvents, cold plastics and Hot way marking involves the use of thermoplastics and thermoplastic tapes yellow color that stick to the asphalt gas burner at temperatures from 5 to 35 degrees.

Cold compounds are recommended for use 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 necessary to use materials that are applied using the hot method.

road AK-511

This is one of the most popular paints for marking roadways and streets. The coating can be used in moderate continental climates. 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 treating public roads.

Road paint dries quickly, has a high level of light resistance and brightness coefficient, which guarantees the visibility of markings at any time of the day. In addition, it has excellent adhesion, wear resistance, resistance to moisture and various chemical compounds.

The enamel can be used with reflective 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 reflection effect is achieved by using reflective elements in combination with enamel, which are applied on top. The advantages of using this composition include:

• compliance of the coating with the requirements set by GOST GOST R 52575-2006;
• resistance to external factors;
• quick application;
• improving the functional properties of road markings.

The average material consumption is 3.5-4 kg/m2, provided that the layer thickness is no 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.

"Technicol" does not need to be diluted, so it is completely ready for use. With its help, you can apply horizontal markings on the roadway, asphalt concrete and concrete covering. The paint is supplied in several modifications, specifically designed for the scope of application - these can be federal, regional or intermunicipal roads, as well as other roads and sidewalks.

Enamel AS-5307 “Line”

This paint is white. It is used when drawing safety lines on asphalt and concrete surfaces. The composition kit includes reflective balls that ensure the glow of the markings - 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 apply markings for any purpose;
• thanks to high brightness, markings are visible even in the dark;
• You can use enamel on any marking machines;
• high adhesion;
• quick drying.

Indecoat-511

Indecoat-511 paint is also widely used. The composition of this coating is a combination of pigments, fillers and targeted additives.

Operation of the applied markings is possible in a wide range 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. Indecoat-511 can be used for marking concrete and cement surfaces.

In the basic version, the paint is produced white, but available in yellow, orange, red and black. A single layer coating accounts for approximately 300-400 g/m².

Reflective materials

So that the yellow paint is clearly visible even in bright sunlight, and on a dark night, in any weather, special reflective glass microbeads are added to it. They are applied to paintwork and refract the light coming from the headlights, reflecting it at a different angle so that it does not fall into the eyes of drivers. These microbeads are applied in several ways:

• are introduced into the marking material in a volume of up to 20%;
• sprinkled over the applied markings in a volume of 200-300 g/m²;
• applied by a combination of both methods.

The dried layer of paint in the marking is approximately 150-300 microns, so the size of the balls must correspond to this value.

Cold plastic

Innovative road technologies also lead to the fact that cold plastic, rather than asphalt paint, is used for marking. The use of such a composition is rational due to its high wear resistance and the ability of long-term operation in any climatic conditions. Markings applied with paints will last a maximum of 2 years, while the service life of cold plastic is significantly longer.

Not so long ago, such materials were not produced in our country, but today you can find compositions domestic production, but using imported raw materials. We offer an overview of the most popular cold plastics today:

1. "Maxidur". This is a white composition that hardens on the surface in literally 30 minutes. To increase the visibility of markings at night and cloudy weather, the coating is supplemented with glass microbeads.
2. "Technoplast". This material allows you to apply thick-layer markings - stop lines, noise lines, pedestrian crossings, directional arrows and much more. TO distinctive features This plastic includes high wear resistance, versatility color solutions, possibility of adding glass beads.

With a coating thickness of 2 mm, on average 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 these purposes. They are attractive due to the increased thickness of the applied layer and, accordingly, a longer service life. On the other hand, thermoplastics are more expensive, so they are mainly used in areas where wear rates are very high. Such markings are applied exclusively mechanized. Popular thermoplastics include:

1. “Marker” is a yellow thermoplastic paint, which is a white free-flowing mixture based on petroleum-polymer resins, plasticizers, synthetic rubber and mineral fillers. Using this composition, you can apply horizontal road markings on roads with heavy traffic and high loads.
2. "Megoplast-Premium". This thermoplastic is used for marking center lines, stop lines and arrows on road surfaces. It is highly resistant to temperature changes and abrasion. To apply the material, marking machines are used on a dry surface.

Thermoplastic consumption for a coating 3-5 mm thick is 8-10 kg/m².

Application paint and varnish materials quite wide and varied. Modern technologies The chemical industry allows them to be introduced into more and more different areas, industries and productions. The development of advanced types of surface coating products is of a specialized nature. That is, a specific purpose of paint requires it to have the necessary properties for this purpose. This increases product efficiency, allowing for reduced volumes consumed in the same area as a result of improved material quality and durability.

Thus, savings occur Money. And this is a very important indicator, especially if the use of paint and varnish products takes place in government affairs, because expenses are covered by allocations from the budget.

There is an expression in Russia that the two main problems that everyone and everywhere encounter are fools and roads. Let's focus on the latter. The condition of the road surface along its entire length leaves much to be desired. There are, of course, individual sections of tracks that meet all the established indicators and do not cause any complaints. But overall the situation is not very good.

This is due to the presence of potholes, uneven surfaces, and incorrect or missing lane markings in some places that motorists should follow. This leads to frequent accidents involving pedestrians, car drivers and trucks. The result is harm to the health and lives of people (mild, moderate, severe), causing material damage to the property of owners, blocking traffic flow and many other negative consequences.

One way to partially solve the existing problem regarding markings would be to use high-quality materials from the paint and varnish industry to apply identification elements to the asphalt surface. This is made possible by the creation of tools whose purpose is to exclusively perform this task.

Now let’s take a closer look at each of the questions: about the marking of the road surface, the paintwork materials for its application (characteristics of each type separately), the ways in which this process can be carried out, technical support, conditions that change the state of the paint present on the asphalt surface.

"Road markings": basic provisions

Road marking is a marking made in a certain way and applied to the road surface. Its main function is to inform moving persons in order to simplify their movement on a dangerous section of the route.

This concept is found quite often in the Rules of the Road. It also proposes its division into two types and the characteristics of each. There are horizontal and vertical markings depending on which surface (horizontal or vertical) the paint coating is applied to.

The application process is regulated by a number of legal acts. Among them are various GOSTs and departmental regulations on construction. For example, GOST R 51256-99.

The quality level of painted traffic lanes is also determined by the indicators of the paint and varnish products, its main features, and the impact it has various factors directly during its operation, too.

Substances for asphalt surfaces are conventionally divided into two categories:

1. Used in most cases. Among them are specialized paints, characterized by particular resistance, and a group of plastics. A big role is given to paints and thermoplastics.
2. Used in certain situations. These are paving stones (made of clinker or ceramics), chips (made of porcelain), concrete (made of cement, asphalt or polymer), buttons (made of metal) and individual blocks.

Paints and varnishes for road surfaces are multicomponent mixtures. They contain 4 or more components: pigments, polymers, additives, fillers. The most important element that determines the quality of markings and its durability is the polymer.

The quality of the drawn lines also depends on the paint application technology. There are two ways: cold and hot. Some paint materials can only be applied in a certain way. The first method allows you not to renew the coating for up to two years. The second is often used on road sites with high speed limits (highways and highways). There is another fairly common group of products that provide light reflection.

Cold method and corresponding paintwork materials

Three groups of paint and varnish coatings are applied in this way:

1. Paints containing organic solvents;
2. Water-dispersed;
3. Cold plastic.

The first type of materials is represented mainly by waterproof paint products. Previously, EP-5155 enamel was used, but its properties were inferior to foreign models. The experience of other countries and our developments were taken into account, and a new type of paint was born - VMD (waterproof road marking).

The second type is different increased level environmental safety, which sets it apart from other “brothers”. However, this also has its drawbacks: a long drying time for the surface, low durability during the operation of the roadway.

Cold plastic significantly improves the last mentioned fact, extending the service life to two, and in some cases, three years. For comparison: usually horizontal markings require a new application after a year. This species appeared in Russia quite recently.

The group of cold-applied enamels includes, in addition to the previously mentioned number:

• 5155,
• AK-505,
• AS-554,
• EP-5327.

Hot type of application of materials

In some aspects, this method is more effective than the previous one.

Its advantages include:

1. Extended service life of hot-applied coatings. This is due to a noticeable thickening of the layer of material used for marking.
2. Less time-consuming production thanks to a fully mechanized process.

But there are also quite noticeable weaknesses, one might even say difficulties. First of all, it is a question of price. Hot production is several times more expensive than cold production. Secondly, constant monitoring of the temperature regime in automobile containers with paints and varnishes is necessary. Thirdly, you need special equipment that is designed specifically for this.

It is easy to guess that the main material intended for this type of application is thermoplastic (“thermo” means heat, heat).

An example of this type of product is thermoplastics:

• "Megoplast"
• "Technoplast"
• TPK-N,
• texture M-1, M-2.

When it comes to applying road markings over large areas, you should give preference mechanized method. There are a number special machines designed for this purpose. Thanks to their use, the level of quality, as well as the correctness of the lines, increases.

Automotive marking equipment must include the following elements:

• technological units;
• temperature control sensors;
• devices for applying lines of various sizes and spraying other components;
• spray nozzles;
• pressure regulator in a container with materials.

Russia usually purchases such equipment from foreign suppliers, who pay closer attention to the development of specialized equipment for applying road markings.

Throughout its service life, the marking line is affected by a number of factors that determine how wear-resistant the coating is. Many studies have been carried out in order to identify them. It was found that the summer season is characterized by less wear of the paint layer than the winter season. It's connected with temperature conditions and sharp transmissions in the cold season.

So, what determines how long it takes for information lines to stay on the road?

1. The degree of change in the structure of the paint and varnish material itself;
2. The degree of change in the structure of the asphalt or concrete pavement;
3. The interaction of the applied substance with the one that is being painted;
4. Influence of temperature conditions;
5. Road congestion with cars (average cross-country ability);
6. Other.

The main element in the composition of paints and varnishes is polymer, as it performs a binding, connecting function.

conclusions

As we can see, the market for specialized materials in the paint and varnish industry intended for road markings is very wide. There are both domestic developments (for example, VMD paint) and imported ones.

The situation on the roads largely depends on the correct organized space roadway. The effectiveness of the marking process depends on the use of a particular material (priority paint with a narrow focus - only for roads), the method of its application (cold or hot), the technique used for road works and not only.

New developments in the Russian chemical industry will further improve the quality of coatings and increase the degree of adhesion to the road surface. The main area that should be given close attention is increasing the service life of paints and varnishes road purposes in order to save money for the state. This can also help to reach more high level market in this area, the emergence of a positive trend in sales volumes of paints and varnishes.

Road markings are important element organization of the roadway. It regulates the direction of traffic flows, pedestrians and other road users, and helps to increase bandwidth roads.

With correctly selected materials for applying markings, you can reduce the consumption of applied material, and using quality product, increase useful term use of road markings. Only high-quality, proven road paints have a high level of resistance to abrasion and harsh weather conditions, and as a result will last a long time.

Let's take a closer look at the requirements of GOST R 50597-93, which road markings must meet.

• Condition of visibility, regardless of time of day and weather conditions
• Resistance to abrasion, deformation under the influence of temperature changes, chemical and meteorological influences
• Adhesion of vehicle wheels to the road to ensure safe movement

There is a varied number of materials used in marking: road paints and enamels, thermoplastics, cold plastics and many other materials with different color scheme and chemical composition. When choosing the material to be applied, the level of load during operation of the marked area is taken into account.

To calculate the operational load of the roadway, a point system is used; the number of points assigned depends on the level of influence of factors on the wear of road markings. For example:

After scoring, the marking area is assigned a class (from one to five)

• 1st class of site: with a total number of points from 1st to 5th
• 2nd grade: 6-10 points
• 3rd grade: 11-15 points
• 4th grade: 16-20 points
• 5th grade: more than 20 points

For each class of road section, a optimal material for marking. Matching the type of area and the selected material will save money, reduce the amount of product applied and increase the life of the marking.

For the first and second class of the site, it is possible to use road paint; for the third and fourth, it is optimal to apply thermoplastic; in the case of the 5th type, cold plastic is applied.

Road paint is used for marking and marking asphalt, asphalt concrete, slag concrete, cement concrete and oil bitumen surfaces of roads and similar transport routes, parking lots Vehicle, runways and taxiways of airfields, tennis courts and other surfaces with road and pedestrian traffic.

Road marking paint is available in several colors:

• Yellow,
• Red,
• Orange,
• White.

Yellow paint for road markings is applied to side curbs, in places where water drains or manholes are located, used to mark bus stops, as well as in areas where stopping and parking of vehicles is prohibited. Orange paint is applied to indicate temporary markings.

All paints we offer for road markings are characterized by high elasticity and high speed drying.

Marking with cold plastic

When it becomes necessary to apply horizontal markings, it is advisable to use cold plastic. Markings applied road paints, at intensive use will last no more than a year. Thanks to its two-component composition, cold plastic has a higher wear resistance. The hardener, which is introduced immediately before application, extends the service life of the marking to 2 years or more.

Hardening time is about 30 minutes. The finished marking, applied with cold plastic, has a coating thickness of 20 to 25 mm.

Thermoplastic for road markings

Road markings produced by hot application are considered more expensive. Thermoplastic markings are justified on highways with a large flow of traffic and other sections of roads with high traffic volumes. The thickness of the marking line reaches 40 mm, and the service life increases for many years.

To ensure the best visibility of markings in the dark, use glass beads or colored chips. To create a safe base for better adhesion to vehicle wheels, an anti-slip coating is applied.

When choosing materials for road markings, do not forget about the harsh climatic factors that affect big influence on the road surface. Managers of the EcoDorSnab company will help you decide and purchase suitable materials for applying road markings.
