Road curb

The most popular decorative road element, which occupies up to 90% of the total volume of material used. The average service life is 15-20 years.

In a number of places, with accompanying operating characteristics, the warranty period is increased to 40 years.

CONTROL METHODS

3.1. Load testing of stones to control their strength and crack resistance is carried out according to GOST 8829.

The diagram and position of the stone during testing are shown in Figure 1 and Table 7.

— control load

Damn.1

Table 7

The maximum width of crack opening when testing for strength and crack resistance should not exceed 0.2 mm.

Load testing of stones is carried out after the stones reach compressive strength at 28 days of age.

3.2. The compressive and tensile strength of concrete during bending should be determined according to GOST 10180 or GOST 17624, or GOST 22690.

When producing stones using the vibrocompression method, which leads to a change in the composition of concrete, a correction factor is adopted for the strength of the concrete of control samples, established experimentally in accordance with the requirements of GOST 10180. In this case, the correction factor should be taken at least 1.

3.3. Frost resistance of concrete is determined according to GOST 10060 or GOST 26134 by saturating concrete stone samples before testing with a 5% aqueous solution of sodium chloride.

In this case, a decrease in the compressive strength of concrete samples is allowed by no more than 5% and a loss of their mass by no more than 3%.

3.4. Water absorption of concrete stones is determined according to GOST 12730.3.

3.5. The workability of the concrete mixture is determined according to GOST 10181.0 and GOST 10181.1.

3.6. The volume of entrained air in a concrete mixture with water-entraining additives is controlled according to GOST 10181.0 and GOST 10181.3.

3.7. Inspection of welded reinforcement products should be carried out in accordance with GOST 10922 and GOST 23858.

3.8. The tension force of the reinforcement, controlled at the end of the tension, is measured according to GOST 22362.

3.9. The dimensions and position of reinforcement products in stone, the thickness of the protective layer of concrete before the reinforcement should be determined according to GOST 17625 or GOST 22904.

In the absence of the necessary instruments, it is possible to determine the specified parameters by cutting grooves and exposing the reinforcement of the stone, followed by sealing the grooves and places where the reinforcement is exposed with fine-grained concrete or the concrete from which the stone is made.

3.10. Dimensions, deviations from straightness and perpendicularity of stones, the width of opening of technological cracks, the dimensions of shells, sagging and edges of concrete should be checked by the methods established by GOST 26433.0 and GOST 26433.1.

The length of curved stones is measured along the upper edge of the convex side, and the deviation of the front surface profile from the nominal curvature is checked with a template.

How to install curbs correctly, before or after laying paving slabs?

It is difficult to answer this question unequivocally, because each option has pros and cons.

• We install immediately.
  This option is good for beginners. Borders clearly frame the area to be improved and simplify the task of maintaining boundaries. To save paving elements, it is necessary to calculate the distance between the curbs, which should be a multiple of the width of the paving stones. When making calculations, it is necessary to remember that there is a gap between the paving elements - 2-4 mm. For beginners, it is better to use the dimensions of a ready-made track.
• We install it after laying the paving stones.
  This choice allows you to use the tiles rationally and avoid sawing them.

TRANSPORTATION AND STORAGE

4.1. Stones are transported by any type of transport in accordance with the requirements of GOST 9238 and “Technical conditions for loading and securing cargo.”

Stones in open cars and on trucks should be transported in container packages in accordance with GOST 20259 or on pallets in accordance with GOST 18343, bandaged with steel tape in accordance with GOST 3560 or wire in accordance with GOST 3282, ensuring rigid fixation and safety of the stones.

4.2. It is prohibited to load stones in bulk and unload them by dropping them.

4.3. Stones should be stored in a finished product warehouse, sorted by grade in stacks or bags up to 2 m high.

4.4. Stones in stacks must be laid on wooden pads with a thickness of at least 30 mm according to TU 400-1-225 or pads made of other materials that ensure the safety of the stones, located vertically one below the other at a distance of 0.2 the length of the stone from the end. The bottom row of stones should be laid on transverse spacers with a width of at least 80 mm.

garden border

As a rule, this type of decorative curb is used in private landscape design. In the visual part, the garden curb has all the signs of a vibro-compressed material, in contrast to the vibro-cast material used to produce a highway or similar road type.

The period of technical operation of such a curb stone is at least 15-20 years. In some climatic areas (temperate and southern latitudes), the service life can be increased to 50 years.

Prices for installing curbstones in the estimate

Prices for installing curbs in the estimate are applied based on the standards from the FER27 collection. This collection combines many norms related to the construction of highways. It should be noted that the standards of the collection take into account not only the creation and arrangement of roads made of asphalt, but also those made of other materials.

As part of this collection, you can find several pricing options for estimates for curb installation. One option is the standards from table FER27-02-010. This table takes into account the construction of side stones made of various materials.

Thus, the norm under the code FER27-02-010-01 is the price in the estimate for the installation of concrete curbs with cement-concrete pavements, and the norm FER27-02-010-02 can determine the cost of installing concrete curb stones with other types of pavements. Standards 03 and 04 in table FER27-02-010 take into account the installation of curbs made of natural stones on the same types of coatings as in norms 01 and 02.

Despite the different types of materials used in the prices in the estimate for the installation of curb stones, the composition of the work of all four standards in table FER27-02-010 is identical. First of all, the scope of work involves the installation of a concrete foundation. This manipulation must be carried out with simultaneous installation and disassembly of the formwork and compaction.

Further, the prices in the estimate for the installation of curbs from table FER27-02-010 include the actual installation of curb stones of the selected type and their trimming. Work on filling seams and jointing them is also part of the scope of work of the norms of the specified table. Cleaning of granite sides is included in the final stage of work according to the standards in FER27-02-010.

The volume of work in the above prices in the estimate for installing curbs is measured in 100 m. It should be noted that the resource part of all standards in table FER27-02-010 takes into account most of the materials necessary for the correct execution of work. However, the brand and cost of the side stones themselves are not taken into account in the standards and must be included in local estimates, local resource estimates and estimates in Form No. 4 separately based on data from the design documentation.

Figure 1. Price in the estimate for installing a curb

The next table in the FER27 collection, which contains prices for estimates for the installation of curb stones, is table FER27-02-011. This table contains the only standard for the installation of side granite stones of the ZGP type. The normal volume of work, as in the norms of the previous table, is measured in 100 m. However, the scope of work is more complex and labor-intensive.

The scope of work in the estimate for the installation of curbs under the code FER27-02-011-01 includes loading of the material, its transportation to the installation site at a distance of 150 m and unloading. Further, the standard provides for the placement of stones along the installation line, the manual installation of a concrete installation layer and the installation of curbs.

In addition, the work of the FER27-02-011-01 standard includes manual edging of stones, tamping with concrete mixture and compaction. Filing and chipping are also part of this standard. The grouting of seams and the preparation of mortar for this are indicated as standard upon completion of the work in the price estimate for the installation of curbs.

Another table in which you can choose the price in the estimate for installing curbstones is FER27-02-015. It contains three standards that take into account the installation of side stones made of monolithic concrete. In this case, the installation method involves the work of a concrete paver-planner. The difference in standards lies in the type of site on which the work is carried out.

Norm FER27-02-015-01 is the price in the estimate for installing curbs on a combined site. Standard 02 in the table takes into account work on a straight section, and standard FER27-02-015-03 on a radial section. The unit of work measurement in the table FER27-02-015 is 10m.

As for the composition of the work and prices in the estimate for installing a curb from table FER27-02-015, it is distinguished by a wide range of manipulations. At the initial stage, the standards provide for the installation of stands under the string, balancing and tension of the string. After this, the concrete paver is balanced and the concrete is unloaded.

Further, the prices in the estimate for installing curbs provide for laying the concrete mixture and monitoring the surface with correction of seams. Coating the finished product with mastic, removing strings and cutting shrink seams are a mandatory part of all three standards in table FER27-02-015. Sealing seams and watering stones are also included in the price list.

Manufacturers

The territories of the CIS countries are rich in granite deposits of the highest quality. Many stones are unique - they have no analogues in the world in terms of color and texture. The increased strength is explained by the fact that Russia, Belarus and Ukraine are characterized by significant temperature fluctuations at different times of the year - this process helps strengthen and harden the rock. In terms of quality, Russian stone is in no way inferior to granite mined in Asia and South America, while being significantly higher in cost. Even Chinese manufacturers known for their dumping policies cannot make better price offers. You don’t even need to mention European countries - their granite curbs are much more expensive.

All activities in the extraction and processing of granite are strictly regulated throughout the world, which is why Russia several years ago adopted new GOSTs, which increased the requirements for the quality of stone and reduced the permissible errors of finished borders.

Today, slab size deviations are 0.2%. This is slightly lower than the European level (0.1%), but at the same time higher than the Chinese one. This creates a significant competitive advantage for the products of the Russian manufacturer and makes the products of our enterprises in demand among domestic consumers.

As for manufacturers, it should be noted that they have earned the trust of consumers. The first lines in the ratings are occupied by “Danila Master”, “Yurgan Stroy”, “Stroykamen”, “Rosgranit” are also known among consumers. Antique Trade, Albion Granite, and Sovelit are not losing ground.

Features of the use of different types of products

It has been used for centuries in various fields:

• in road construction to separate the pedestrian traffic area from the roadway. This allows you to create safe conditions for movement, and also fixes the road surface;
• for the improvement of recreation areas, landscape design, as well as for the design of garden plots. It separates green spaces, protecting the soil from being washed away by water.

The product is made from high-quality concrete mixture using the method of semi-dry vibration pressing, which allows for improved performance characteristics. The regulatory document allows for production from granite stone, as well as reinforced concrete.

Curbs made by semi-dry vibrocompression have high quality characteristics

GOST classifies edge stones according to types, which differ in their area of ​​application:

• road. It is in demand during the construction of roads in populated areas, when creating a boundary between the roadway and the pedestrian area. The stone ensures the integrity of the road surface, making it difficult to move under loads, and also strengthens the paving surface;
• mainline It is used in the field of road construction in the construction of highways located outside populated areas. According to the standard, it is made of high-grade concrete, which increases its strength and service life. Features increased length;
• sidewalk. Indispensable when carrying out measures to improve park areas, city squares, paths, squares, sidewalks. Provides protection for lawns, flower beds, and flower beds from erosion as a result of intense precipitation. Characterized by a variety of shapes and colors;
• garden. The cross-sectional shape resembles a paving stone, but has an increased length and a reduced width compared to a sidewalk stone. It is used when creating recreation areas, landscaping parks, designing public gardens, as well as decorative finishing of lawns in summer cottages;
• lawn It is a fairly popular type of curb stones. It is used as a decorative element when designing paths and flower beds located in summer cottages, as well as when laying out garden areas. It is characterized by a reduced size in height and low weight.

The main types of vibropressed curbs are main curbs, road curbs and garden curbs.

Production

For the manufacture of road curbs, concrete of the so-called heavy grades is mainly used, which correlates with the use of reinforcement. In the latter case, it is assumed that steel frames will be used, which are created using AIII and AI reinforcement, as well as BpI reinforcing wire. In order to increase the strength of the reinforcement, steel products that have undergone heat treatment can be used.

The actual process of producing road curbs is based on the following types of work:

• prepare a concrete mixture (having a composition depending on the purpose of the side stone), which is then mixed;
• Pigments are added as necessary to give a particular color to the products;
• the mixture is poured into molds of various configurations, for example, a square or a semicircle, which also depends on the purpose of the final product;
• start the molding process using the vibration pressing method;
• after this, the products enter special chambers for drying;
• finished borders are removed from the molds.

A special feature of the side stone is that each copy is supplemented with mounting loops that simplify loading and unloading operations.
