Technology of soil stabilization

ROAD BASE

of stabilized soil allows to get

qualified road with statement with cost

from 640 roubles/m2

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

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.)

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

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.


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.


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.


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.


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.


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.


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

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.

Object: city of Klin,

logistic terminal

Site preparation for construction of logistic

terminal and approach roads





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.

Object: village Kryvtsi,

Ramenskyi district

Road bedding (for subsequent covering by

road carpet) in the cottage settlement under

construction.





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.
