prior research
Detailed results of the preliminary study are crucial for individual planning of construction activities and increase the life of the road base service. The more accurate the information collected, the more optimal engineering calculations will be selected.
Based on the scientific conclusions of the geological and mechanical properties of the individual layers, we choose the most economical calculation and formulation of the materials used to ensure the maximum economic results.


construction technology

  • loosening Screening, grinding and homogenizing material existing carrier layer.
  • binder distribution via tsementoraspredelitelya.
  • Adding soil stabilizer "STABILAR" and "Stabilar E-95"  using a mill or the recycler through adjustable nozzles.
  • mixed Screening.
  • surface profiling.
  • sealing.
  • The final shaping and sealing surface.
  • watering water.
  • Additional surface treatment, If you want to (protection from drying).
  • Within 12 hours of the road can be opened to traffic or perform further work.

astringent
The binder may be used according to the cements to GOST 31108-2003 or a suitable cementitious composition, It carried out within a specific project, depending on the mixture composition and environmental conditions.
The volume of added binders, usually 4-9 % from the mass of soil.
The calculation of the addition amount of the binder is carried out according to the technical requirements of the grounds on the basis of the results of laboratory research.


Emulsion soil stabilizer "STABILAR" and "Stabilar E-95"


An emulsion is a water-based, surfactants, adhesive substances and materials, which maintain and improve the hydration of the hydraulic binder, which contain preparations to impart water resistance .
The amount of added emulsion is, usually 10-12 l / m³ compacted soil with cementitious mix.
This emulsion is produced at the enterprise LLC "New Roads".
Adding soil stabilizer "STABILAR" and "Stabilar E-95" determination is carried out with the water content of the soil with cementitious mix during the mixing process material in situ.
The required ratio of water and soil stabilizer "STABILAR" and "Stabilar E-95" selected according to the specifics of the project, depending on the technical requirements for grounds.

Initial primer / mixture
Stabilized carrier layer (SNA) formed by mechanical grinding and homogenising the components used binders and soil. The mixing ratio depends on the kind of soil to be stabilized.
Quality control
In the process of construction works carried out quality control and soil mixed with binders and SNA. In particular, controlled:

  • Determination mixtures humidity.
  • The amount of added binder.
  • The amount of water added and the polymer mixture.
  • layer thickness.
  • compression ratio.
  • The evenness of the surface and cross section.

Control of the amount of added binder is required to comply with the recipe mixture chosen for the study.
Control of soil moisture is needed to estimate the amount of added water and soil stabilizer for further mixing with binders.
Control of layer thickness, degree of compaction, flatness and the transverse profile is required to comply with technical requirements.


The above soil stabilization technology is governed by the following documents:

  • GUEST 30491-97 Mixtures of organo and soils, fortified organic binders for road and airfield construction.
  • GUEST 23558-94 Mixes rubble-gravel-sand and soil, treated inorganic binders for road and airfield construction.
  • ODM 218.3.076-2016

Methodical recommendations for the construction of bases pavements using associated soils, fortified mineral or organic binders with additives of surfactant and industrial wastes.

Generally described soil stabilization technology allows to condition the materials of the carrier layer and ground so, so that they become the raw material for a variety of applications in the process of excavation, as well as road construction and civil engineering. Besides, astringent stabilization "STABILAR" and "Stabilar E-95"  permits the intended use is usually unsuitable for the construction of soil types, eg: clays and loams. As a result of this technology is the construction and technical, economic and ecological alternative to the use of foreign materials and special events to strengthen the soil.

Before working with this technology for the repair of bearing layers of road surfaces, carried out specific research on the basis of samples taken mixed material.

Research is needed to calculate the required content of binders and soil stabilizer "STABILAR" and "Stabilar E-95" . The results of research are the basis for the subsequent quality control in the course of work.
