ROAD CONSTRUCTION

A modern road is a complex transport structure consisting of several structural layers. In addition to the construction of the carriageway, the road is equipped with a water drainage system, engineering connections to ensure its normal functioning and a well-equipped perimeter.

Modern road construction technologies and the use of high-quality building materials make it possible to build solid and reliable roads in a short time span 10 years. Many types of specialized construction equipment are used for the construction of the road - excavators, graders, bulldozers, dump trucks, asphalt stowage, rollers, etc. The use in the construction process of particularly durable concrete structures - road and airfield slabs, rings and wells, reinforcement blocks, trays and pipes make the road fabric especially durable.

ROAD TYPES

Today there are three types of roads classified as motorways, expressways and general roads. Roads can also be temporary and permanent. According to the technical characteristics of the road: traffic intensity and permitted speed, maximum load, capacity, availability of road infrastructure are divided into five categories. The higher the category of road, the higher the construction and equipment requirements.

FEATURES OF ROAD BUILDING TECHNOLOGY

The quality of road construction directly influences the durability and efficiency of road use and road safety. A modern road is a particularly solid structure, consisting of several layers of dirt, and road construction involves several mandatory steps.

It is no secret that the accumulation of water on the road hinders the movement of vehicles and worsens the condition of the road, so before a road can be built, a system of water drainage must be made both inside and outside the town or town. Outside the town, there are roadways, where water flows from the carriageway by inclination in the longitudinal and transverse directions of the road. A drainage system with reinforced concrete trays is installed in the town or village, where water from the road flows into the general sewage system.

PREPARATION OF THE GROUND

Laying of the road on unprepared ground will quickly render the road useless, therefore a base is made under the road surface.

Removes the top layer and aligns the ground.

Preparation of a trench for stowage. The depth of the trench depends on the type of soil, and can be between 25 and 50 cm.

Laying of geotextile layer for hydroinsulation of plates, prevention of soil leaching and growth of vegetation.

The formation of a pillow made of sand and bristle, the thickness of a layer of crushed stone can be from 5 to 10 cm, career sand - up to 30 cm. The layer of sand is washed with water during the tram. The surface of the base shall be as level as possible, which shall be controlled by a level and a rope beacon.

LAYING OF REINFORCED CONCRETE PLATES

Reinforced concrete slabs are arranged successively on the prepared base. The slabs can be laid with a small distance between them, which is filled with sand and wetted, or on a cement-sand solution. The plates are laid as precisely as possible using the building level. A layer of asphalt is placed on concrete slabs, although in the case of a temporary road, asphalt may not be laid. The plates can be used in any climatic zone and on any soil.

The final stage includes beautification of the area adjacent to the road, road markings, signs and kerbs.

ADVANTAGES OF USING THE CONSTRUCTION OF ROADS

  • High editing speed.
  • The PBJ is the perfect basis for asphalt coating.
  • Minimal time and cost for preparation of the ground.
  • The plates can be reused.
  • They are suitable for constructing roads in any climatic zone and on any type of soil.

OTHER ROAD SURFACES

In addition to WBI designs, road boards are made of heavy reinforced concrete. Road slabs over 6 meters long are used for the construction of expressways. They can withstand heavy loads, including heavy tonnage transport, and are resistant to temperature and chemical effects.

Airfield runway coating uses airfield slabs which are made of high-strength heavy concrete and reinforced base. They are capable of withstanding maximum loads and have high strength, durability and reliability. In addition to the construction of runways, they are used for the installation of towers for cranes, the laying of motorways for the passage of large-capacity vehicles and special equipment, etc.

In addition to reinforced concrete slabs, other LBIs are used in road construction, transport infrastructure and adjacent areas - concrete stones and trays, concrete rings and wells, pipes for the extraction of water of different diameters, sturdy and fortification blocks, etc.

LLC Limak Marash has many years of professional experience in the construction of roads and highways, bridges, transport tunnels, interchanges, airfields and other road constructions throughout Russia. We carry out the complex of construction and construction works under the turn key, ensuring high quality, strict observance of time for road construction and optimal prices for our services.

Thanks to the use of modern design technologies (BIM), the time-frame for the creation of the project is shortened, the quality and time-frame of the construction works are increased. Optimization and informatization of all construction processes allows saving human and financial resources, which ultimately reduces the cost of construction.

We work under the terms of the EPS contract and perform all the engineering, supply and construction works. The contract defines the amount and plan of financing of the facility, the quality requirements, the phases and terms of the construction work, the time of commissioning the facility, while the cost remains fixed.

One of the directions of LLC Limak Marash is road construction. International units of «Limak Group» have built a lot of objects all over the world - road Espiye - Charshi Bashi (Turkey) with a length of 61 km, including 9 bridges, 6 traffic interchanges and 4 tunnels, section of road Eminlink - Çiftehan with 15 viaducts and 6 double-bore tunnels, the II section of the Bozuyuk - Mikeje motorway with a length of 44 km and a length of the fourth tunnel in Turkey, as well as 7 overpasses, 12 subways, etc.

We have sufficient resources and experience to realize any road construction. For any questions, please call +7 (495)-626-40-50 or e-mail info@limakmarash.com.
