The document discusses a road base construction technology using stabilized soil that allows for the creation of quality roads at a cost of 640 roubles/m2; the technology involves granulating and mixing local soil with binding materials like cement or bitumen before grading and compacting it into a stabilized base that provides benefits like frost and erosion resistance at a lower cost compared to traditional road construction. The technology can be used to construct various types of roads and worksites and offers advantages like flexibility, cost savings, and a 5-year guarantee.

1. ROAD BASE
of stabilized soil allows to get
qualified road with statement with cost
from 640 roubles/m2

2. Essence of the technology
With the use of special equipment complex, existing soil is granulated intensively
and intermixed with corresponding binding materials, and after that it is graded and
compacted.
Traffic
direction
Water or
bituminous emulsion
Cement
Broken stone (in
necessary)
Local soil
Stabilized base
Mixing of
optimally
selected alloy

3. Application
Construction of asphalt roads
(from federal highway to usual road in the
cottage settlement)
Construction of approach and technological
roads (farm enterprises, barrow pits, building
sites etc.)
Preparation of building sites
(territories and bases for buildings of logistic
terminals, warehouses etc.)

4. Advantages
Water doesn’t come to the base of road pavement:
- resistance to erosion
- resistance to slaking
- frost resistance, frost boil is excluded
High modulus of elasticity, shear-resistance, flatness:
- allows to reduce the thickness of asphalt to 4 cm
- excludes subsidence and rutting
- excludes appearance of “copying” breaches on the asphalt
Flexibility of application:
- you can make any loads on the stage of projecting
- receipt of mixture (alloy) is being adapted to local materials
- significant economy on materials and equipment

6. Technological process
1.Soil analysis
1. Excavation of soil samples
2. Laboratory analysis of samples:
- particle-size composition
- percentage of clay particles and dust
- definition of number of soil plasticity
- control of pH soil in soil-water extract
3. Laboratory selection of mixture receipt:
- optimization of particle-size composition
- definition of optimal humidity
- definition of maximum density
- ultimate compression strength in dry and capillary
water saturation
The practice shows that engineering project
of the road need to be corrected after laboratory
analysis of soil.
Almost all projects contain omissions (faults)
that lead to useless excess consumption of
materials and to premature destruction of the
road base.

7. Technological process
2. Site preparation
1. Topsoil excavation
2. Drainage construction
3. Preliminary grading
Preliminary grading makes the basis for qualified
realization of the project.
Very often contractors save money on this stage
or execute work not in so high quality due to obsolete
equipment. This not only reduces the working life of
the road but reduces comfort of riding on it.

8. Technological process
3. Adding binding materials
Adding cement with the use of binder
spreader to obtain accuracy of entering
according to the requirements of composition
It is important to provide maintenance of
composition: if there will be too much cement – the
base will split after winter and if there I too little
cement the base won’t be solid enough.
We met contractors who put bags of cement on
the ground or pulverized cement right from the pipe of
cement carrier.

9. Technological process
4. Recycling
Intermixing of soil with the use of
recycler – technics that allow to get
qualified mixing due to fine adjustment
It is important to control % of soil humidity
according to the project. With insufficient humidity
you can connect machine-water carrier to recycler.
Abundant or insufficient humidity will obstacle
the reaction and will make the road base useless.

10. Technological process
5. Compaction
Soil compaction by the vibratory padfoot
drum soil compactor 16-20t
Number of passages is corrected on the basis
of intermediate measures on the site of work
execution
Very often the following mistakes take place:
- underconsolidation for the whole depth due to
incorrect selection of series of compactors and
operation mode;
- softening of the base due to the expiration of
setting time or due to too big number of passages.

11. Technological process
6. Shaping
1. Creating of necessary longitude and
cross sections by grader, leading road
surface to shaping elevations
2. Final compacting of upper layers of the
road base by pneumatic tired roller
All works with soil mixture could be executed
not later than 3 hours since the moment of
interference of recycler. After 3 hours the setting
reaction is over and the subsequent works of
stabilization and road grading only disarrange its
structure and make inappropriate for use.

12. Technological process
7. Quality control
The final stage of works is making control measures
of modulus of elasticity with the use of the device
Terratest-3000
This indicator allows to understand that the works are
executed in high quality , the road base corresponds the
project parametres and is ready for the following covering
by the road carpet- asphalt and concrete, crushed asphalt
or other coverage.
Due to profound knowledge of technology, rich
practical experience and presence of all necessary
technics and equipment, we give you the biggest
guarantees on the market- 5 years

15. Object: village Koskovo,
Solnechnogorskyi district
Construction of approach road to the locality
Scope of works: 17 000 m2
Works are executed during 4 days
20 sm – stabilized base
5 sm – asphalt
750 roubles/м2 – total cost
For setting the road carpet were used waste
products of the local borrow pit. Due to the low
intensivity of traffic and loads on the axle, the
depth of soil stabilization composed 20 sm.
These decisions allowed to reduce
significantly the total cost having saved quality
indicators.

16. Object: city of Klin,
logistic terminal
Site preparation for construction of logistic
terminal and approach roads
Scope of works: 25 000 m2
Works are executed during 7 days
30 sm – stabilized base
500 roubles/m2 – total cost
The decision to apply technology of
stabilization while constructing the object was
taken by the customer due to the necessity of
execution of works as soon as possible and it
was impossible to make applying classical
methods.
As a result of applying this technology not
only the quick result was obtained but also the
significant economy of funds.

17. Object: village Kryvtsi,
Ramenskyi district
Road bedding (for subsequent covering by
road carpet) in the cottage settlement under
construction.
Scope of works: 34 000 m2
Works are executed during 10 days
22 sm – stabilized base
609 roubles/m2 – total cost
Taking into consideration supposed high
intensivity of transport traffic with light load on
the axle it was decided to enter into the
composition of mixture of bituminous emulsion
for the improvement of parametres of the base
and to reduce the depth of stabilization due to
increased parameters in order to save funds.
