Road marking materials. Road marking materials. Technical requirements for road marking materials

Road markings are made with enamels (paints), thermoplastics, cold-applied plastics or other durable materials(polymer tapes, retroreflectors) according to the technical documentation approved in the prescribed manner. Thermoplastics must comply with STB 1090, enamels - STB 1089, cold-applied plastics - according to RD 218 BSSR 29-88.

The main materials used for horizontal road markings in Gomel, are enamels.

Enamels and paints (hereinafter referred to as paints) are suspensions of highly dispersed pigments and fillers in varnishes or aqueous dispersions of synthetic polymers containing functional additives (dispersants, stabilizers, plasticizers, etc.) that form solid opaque solids after drying. paint coatings.

Cold applied plastics - marking materials based on reactive monomers, containing pigments and fillers, forming after chemical curing solid opaque paint coatings with high functional durability. There are spray plastics (application thickness from 0.5 to 1.0 mm) and thick-layer plastics (application thickness from 2.0 to 3.0 mm).

Thermoplastics are thermally softened plastic materials based on a polymeric binder containing pigments and fillers that form thick-layer opaque paint coatings with high functional durability after hardening.

Polymer tapes - products made from polymer materials designed for horizontal road markings.

A clear advantage of paints is the low cost of both the material itself per unit area of ​​marking compared to the use of plastic materials, and technological equipment to apply it. It should also be noted a short time drying of the material (paint), as well as the possibility of stencil application of marking elements of complex configuration.

Unfortunately, there are also disadvantages. The main drawbacks of the paint are the high content of solvents (up to 60%) and the use of polymers in its formulation, which do not provide the enamel with the necessary light resistance and strength, which causes its rapid abrasion during the operation of the marking.

The second widely used material is thermoplastic. This type of material does not contain solvents, and the fluid properties of thermoplastics necessary for marking are acquired as a result of melting at a temperature of 150 - 220°C. The main disadvantage of thermoplastics is the need to heat the material before use. Horizontal road markings made of thermoplastic have a much greater functional durability than in the case of paints.

As an alternative to thermoplastics, cold plastics have been introduced, which do not require heating for their application, and in their original form are a fluid mixture of the main components and a separately applied hardener. As a result of their mixing, a material is formed that creates elements of horizontal road markings. The use of cold plastics is constrained by relatively high cost and a small number of machines. However, it should be noted that cold plastics not only have good prospects for use in various climatic conditions, but also, perhaps, in some cases there may be optimal material for horizontal road markings.

Polymeric tapes are road marking products and are used experimentally. Currently, polymer tapes are not widely used. Manufacturing polymer tapes in the factory allows you to achieve high and stable quality, but to achieve good results, you also need to carefully follow the marking technology. The cost of horizontal road markings made of polymer tapes is very high and exceeds the cost of markings made with cold plastic, which is its main disadvantage.

All marking materials used must comply with the requirements of STB 1520 and be made according to the recipe and technological regulations approved in the prescribed manner. The color of marking materials must comply with the requirements of STB 1231.

In terms of physical and mechanical indicators, marking materials must comply with the requirements specified in Table 1.2.

Application paintwork materials quite wide and varied. Modern technologies chemical industry allow to introduce them all into new and new all kinds of areas, industries and industries. The development of advanced types of products used for coating surfaces is of a specialized nature. That is, a certain purpose of paint requires that it has the properties necessary for this. This increases the efficiency of the product by reducing the volume consumed in the same area as a result of improved material quality and durability.

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

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

This is due to the presence of pits, irregularities, incorrect or missing marking lanes in some places, which should be used by motorists. This leads to frequent accidents involving pedestrians, car drivers and trucks. As a result - causing harm to the health and life of people (mild, medium, severe severity), causing material damage to the property of the owners, blocking the traffic flow and many other negative consequences.

One way to partially solve the existing markup problem is to use high quality materials paint and varnish industry for applying identification elements on an asphalt surface. This is made possible by the creation of tools whose purpose is the exclusive accomplishment of this task.

And now let's take a closer look at each of the issues: about marking the roadway, coatings for its application (a characteristic of each type separately), ways in which this process can be carried out, technical support, conditions that change the state of the paint on the asphalt surface.

"Road markings": basic provisions

Road markings are markings made in a certain way and applied to the road surface. Its main function is to inform people on the move in order to facilitate their movement to dangerous area way.

This concept is quite often found in the Rules of the road. It also proposes a division of it into two types and a characteristic of each. There are horizontal and vertical markings, depending on which surface (horizontal or vertical) the paintwork 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 the painted traffic lanes is also determined by the indicators of paint and varnish products, its main features, and the impact that is exerted by various factors directly in the process of 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 special resistance, a group of plastics. Big role assigned specifically to paints and thermoplastics.
2. applied in certain situations. These are paving stones (from clinker or ceramics), crumbs (from porcelain), concrete (from cement, asphalt or polymer), buttons (from metal) and individual blocks.

Coatings for the roadway are multi-component mixtures. They contain from 4 or more components: pigments, polymers, additives, fillers. Most important element, which determines the quality of the markup, its durability, is a polymer.

The quality indicator of the drawn lines also depends on the technology of applying paint. There are two ways: cold and hot. Some inks can only be applied in certain ways. The first method allows you not to renew the coating for up to two years. The second is often used on road objects with an increased speed limit (highways and motorways). There is another fairly common group of products that provide light reflection.

Cold method and corresponding paintwork materials

In this way, three groups of paint and varnish coatings are applied:

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

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

The second kind is different. increased level environmental safety, which distinguishes it from other "brothers". However, there are also disadvantages here: a long period of drying of the surface, a low indicator of durability during the operation of the roadway.

Cold plastic significantly enhances the last mentioned fact, extending the service life to two, and in some cases three years. For comparison: usually horizontal marking requires 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 life of hot applied coating. This is due to a noticeable thickening of the layer of material used for marking.
2. Less time consuming production due to fully mechanized process.

But there are also quite tangible weak spots one might even say complex. First of all, it is a question of price. Hot production is several times more expensive than cold production. Secondly, it is necessary to constantly monitor the temperature regime in automobile capacities with paint materials. Third, you need special equipment which is designed for just that.

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

Thermoplastics are examples of this type of product:

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

When it comes to road markings large areas, should be preferred mechanized way. There are a number of special machines designed for this. Thanks to their use, the level of quality increases, as well as the correct design of the lines.

Marking automotive equipment should include the following elements:

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

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

Throughout the life of the marking line, a number of factors affect how durable the coating is. A lot of research has been done to find them. It was found that summer season characterized by less wear of the paint layer than winter. It's connected with temperature regime and sharp transmissions in the cold season.

So, what determines how long the information lines stay on the road?

1. The degree of change in the structure of the paintwork material itself;
2. The degree of change in the structure of the asphalt or concrete pavement;
3. The interaction of the applied substance with that which is subjected to coloring;
4. Influence of temperature conditions;
5. Road congestion by cars (average traffic);
6. Other.

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

findings

As we see the market specialized materials paint and varnish industry, intended for the application of road markings, is very wide. There is how domestic developments(for example, AMD 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 one or another material (in the priority of paint of a narrow orientation - only for roads), the method of its application (cold or hot), the equipment used in roadworks and not only.

New developments in the chemical industry in Russia will further raise the quality level of coatings, increase the degree of adhesion to roadway. The main direction that should be given close attention is to increase the service life of paints and varnishes. road destination in order to save government money. It can also lead to more high level market in this area, the emergence of a positive trend in sales of paints and varnishes.
