The main function of the side stone is to visually and physically limit the area of the roadway, sidewalks, lawns, flower beds, trees. It, as a structural part of the road, prevents the flow of storm water into the areas of movement of people and vehicles . Sewage receivers are installed along it. Such a system makes it difficult to displace the soil and prevents mechanical damage, as well as cracks in the pavement.

In Russia, floorings along houses and courtyards were historically made of logs . The fashion for cobblestone pavements came from European countries, where less durable wood was much more expensive. In the lowland Slavic cities of the 18th century, the cost of paving stones was prohibitive, and fragile bricks were used to frame the streets in the county towns, which stood out for their monotony and neatness at first, and then needed to be replaced. The tradition has been preserved on the backyard plots of private buildings and summer cottages.

It is believed that the brick should be buried in half with a narrow end downwards, so it will last longer.

Standard sizes

So, a modern curb is produced industrially, it is easy to install and replace. State standards take into account the need to match the shape of the relief, namely:

• with a tray - BL;
• broadened - BU;
• straight;
• with a break in broadening - BUP;
• privates - BR.

The widest part of the structure - the outsole defines the brand, the lettering - the type of configuration. The parameters are selected according to the approved project within the following generalized data.

Appointment	dimensions (from-to) are in cm.
	length of the product	width is	the height should be
for highways	100-300	8-30	20-60
for pedestrian sidewalks	40-100	4-18

In road construction, a reinforced concrete curb 300x18x30 cm, respectively, is widely used. Technologically, the internal structure of the finished product is provided by a special machine that combines simultaneous vibration and pressing. Such equipment has taken the process to a new level in terms of the quantity and quality of the assortment.

Literally 30 years ago, the solution was filled into molds, dried in a natural way, and since the territory of the enterprise and the number of formworks are not infinite, the range of casting was small, which differs from the samples presented at the present time.

Custom dimensions

The dimensions of a non-standard curb are used to hold decorative tiled coverings of alleys and recreation areas. They are installed in a pre-dug trench on a mixture of sand and cement, under which there is an interlayer of crushed stone of fine fractions, after which they are fixed on both sides with a solution. Installed end-to-end on straight sections, on curved sections, the ends are cut. Oversized include:

• small light elements with a chamfer, decorative pattern, color that matches the tile;
• there are granite types that correspond to the natural color scheme, as a special decor, they are combined with the decoration of the plinths of the facades of houses;
• sometimes framing is made from storm drain trays;
• natural sandstone, shale, evenly cut, polished at the edges in random order look great;
• there are safe forms made of crumb rubber for playgrounds and sports grounds.

Appointment	dimensions (from-to) in cm.
	length	width	height
cast for garden and alleys	50-39	8-3, 5	20-19
granite	70-200	8-20	15-60

Basalt, granite, even sandstone have a very attractive texture and a rather high price, which includes extraction, processing, storage, delivery. Based on this, yellow, gray, brown colored frames are considered popular. The shades are influenced by the color of the sand. The curb must be combined with the background of the track or site.

Selection Tips

For the arrangement of intra-quarter roads, only the materials provided for by the project are used. Accordingly, an independent choice of structural elements is possible only for private homestead construction. The standard for the elevation of the side stone above the asphalt in accordance with GOST is 15 cm, at transitions up to 4 cm, however, with a tiled surface it fits on the same level with the surface or exceeds by 1-2 cm. The selection criterion is the price, which directly depends on the quality, which is influenced by the composition of the ingredients:

• the concrete grade must combine strength, inertness to moisture, frost;
• reinforced concrete is resistant to shock, stress, vibration;
• stability is provided by basalt crumb, which has a significant weight;
• lightweight versions are made of foam concrete with slag filler.

Modern materials make it possible to select samples for specific purposes with the broadest cost policy. A low price indicates a mismatch between processing and production . When buying, you should focus on the certificates of the purchased goods, which indicate the brands of cement, types of filler, types of fittings. It can be added that work done without taking into account regulatory documents will lead to erosion, destruction of landscape design. For example, a product is capable of absorbing water up to 5-6% of its weight. Climatic operating conditions are also important.

Standard frost resistance provides for up to 250 seasonal changes in freezing, thawing, and complete drying temperatures - roughly 30-35 years . It turns out that the conditions in the middle zone are worse than in the northern regions, where there are fewer such surges. An example of reliability are the tracts of the Roman Empire, which have survived in some countries to this day. Half-meter, hand-hewn, tightly fitted to each other, granite or tuff blocks amaze with the scale of the work performed. The practical value is undeniable, since the rains that eroded the masonry over the centuries did not cause fatal damage leading to the destruction of the transport systems of the Romans.

Correctly selected, calculated, installed highway fencing will preserve urban, personal property, and on a national scale, the routes for the transport of goods.
