12.6.7 Test Requirements
11.6.7.1 Unconfined compressive strength test
This test is carried out on cylindrical or cubical specimens prepared by mixing the soil at a
predetermined moisture content and stabilizer content and compacting the mixed material into a
mould at either a pre-determined density or at a given compactive effort. The choice of specimen
size and shape depends on the grading of the soil; it is clearly desirable to keep as small as
possible the ratio of the maximum particles size to the smallest dimension of the mould the tests
shall be carried out as per clause 4.7 of IRC:SP:89-2010
12.6.7.2 Durability of stabilized materials
In order to check the durability of the stabilized mix for sub –base/base, the methods used shall
be as per clause 4.7.2 of IRC:SP:89-2010
12.6.8 PERFORMANCE BEHAVIOR
12.6.8.1 The resilient modulus and permanent deformation are important properties and shall be
evaluated. The performance evaluation shall as per clause 6.1 of IRC: SP: 89 (Part II) 2018.
12.6.8.2 Manufacturer of a CCS shall submit report on performance evaluation done by reputed
Government Organization/Institution like NIT‟s, CRRI, IIT‟s or any NABL approved laboratory.
12.6.8.3 The performance evaluation report of roads constructed with such stabilizers shall be
evolved after two years of trail with a frequency of two times every year.
12.6.8.4 Routine visual observations shall be taken and recorded monthly.
12.6.9 QUALITY ASSURANCE
12.6.9.1 General
During the construction process regular checks are to be made on the stabilized material to ensure
that all the requirements of the specification are being met. Many of the checks carried out are
merely “good housekeeping” i.e. continual supervision to ensure that the construction process
allows the design objective to be achieved in full. In addition to this there are production control
tests carried out to monitor the work in progress to ensure, for examples, that the correct
thickness of stabilized layer is being laid and that a consistent product is being produced. Finally
compliance tests are to be carried out on the finished product to demonstrate that it meets all the
requirements of the specification.
This chapter, therefore, describes the tests that may need to be carried out to check on the quality
of the material. It also discusses the various factors that influence the choice of a particular test
that is used to establish the values for parameters such as moisture content, compacted density,
strength, etc., set out in the specification.
12.6.9.2 Preliminary Trial
As part of the quality control and in order to make a final decision on moisture content and
stabilizer content, the information gained in the laboratory test should be related to preliminary
field trial. These shall be as per clause 6.2 of IRC: SP: 89-2010.
12.6.9.3 Sampling and Testing Frequency

Signature of Contractor For Accepting Officer
Samples for checking the moisture content, strength, etc are most conveniently taken from the
laid material before compaction. Frequency of testing depends on the size of the project and the
facilities available on site but regular checks should, at least, be made on the moisture content,
strength and in-situ density. Whatever the frequency, sampling should be spread out over the site
so as to give representative indication of the quality of the material within a given area. All the
activities of sampling and testing shall be carried out as per clause 6.3 of IRC: SP: 89-2010
12.6.9.4 Storage and Handling of the Stabilizer
Unless cement is properly stored and used in a fresh condition the quality of the pavement layer
will be substantially reduced. Cement must be stored in a sound water-tight building and the bags
stacked as tightly as possible. Doors and windows should only be opened if absolutely necessary.
The cement which is delivered first should be sued first. The storage and handling of cement shall
be carried out as per clause 6.4 of IRC: SP: 89-2010
12.6.9.5 Control of the Moisture Content
Throughout the stabilization work, the moisture content should be maintained slightly above its
specified value. This means that rapid determination of the in-situ moisture content is necessary to
allow adjustments to be made so as bring the moisture content of the stabilized material to the
required value. This shall be carried out as per clause 6.5 of IRC: SP: 89-2010
12.6.9.6 Control of the Stabilizer Content
Mechanical method of spreading the stabilizer should be employed, it is important that a uniform
spread rate is achieved as this will affect the uniformity of the stabilized material.
As mechanical spreader is used, metal trays or canvas sheets, one meter square, should be placed
at regular interval along the road to check the application rate.
The control for stabilizer content for mechanical spreader needs to be carried out as per clause 6.6
of IRC: SP: 89-2010
12.6.9.7 Routine Strength Determinations
Continuous monitoring of the strength of processed material is required to ensure that the
specified strength is being achieved. Representative samples of the full depth of mixed material
should therefore be taken from the site immediately prior to compacting the material. The routine
strength determinations should be carried out as per clause 6.7 of IRC: SP: 89-2010
12.6.10 Strength and Quality Control
Control on the quality of materials and works shall be exercised by the Engineer in accordance
with Section 900.
Cement treated soil sub-base/base shall be tested for the unconfined compressive strength (UCS)
value at 7 days, actually obtained in-situ. In case of variation from the design UCS, in-situ value
being on lower side, prior to proceeding with laying of base/surface course on it, the pavement
design shall be reviewed for actual UCS value. The extra pavement thickness needed on account of
lower UCS shall be constructed by the Contractor at his own cost.
12.6.11 Weather Limitations
Stabilization shall not be done when the air temperature in the shade is less than 100c.

except that cement or lime plus cement as the case may be, shall be used as the stabilizing
material in place of lime.
12.6.14 Moisture Content for Compaction
The moisture content at compaction checked vide IS:2720 (Part 2) shall not be less than the
optimum moisture content corresponding to IS:2720 (Part 8) nor more than 2 percent above it.

During the period of construction, arrangements for traffic shall be provided and maintained in
accordance with Clause 112.

12.7. PRECAUTIONS TO BE TAKEN WHILE USING STABILIZED MATERIALS
12.7.1 General
The two major problems that arise with the use of stabilized materials in road pavement layers are
cracking and the long-term durability of the material. The extent to which either of these is a
problem is intimately related to the purpose of the stabilized layer in the road pavement as a
whole and it is, therefore, difficult to divorce the tow factors. However, in this Chapter the
problems that can arise are discussed.
12.7.2 Cracking is Stabilized Layers
Many factors contribute to the cracking and crack-spacing of stabilized pavement layers. Some of
them are listed below:
1) Tensile strength of the stabilized material;
2) Shrinkage characteristics;
3) Volume changes resulting from temperature of moisture variations;
1) The subgrade restraint;
2) Stiffness and creep the stabilized material, and
3) External loadings such as those caused by traffic.
CA No. CE (P) SWTK/ /2019-20 P a g e | 74
Tender No. CE (P) SWTK/23/2019-20
Signature of Contractor For Accepting Officer
As in the case of compressive strength, the tensile strength of stabilized materials takes time to
develop. On the other hand, stabilized material in a road pavement layer will be subject to volume
changes from at least one of the factors listed above as soon as it is compacted. Cracking in
stabilized layers due to changes in temperature of moisture content cannot, therefore, be avoided
and must be accepted as inevitable although steps can be taken to reduce the effect. Cracking
may also occur as a result of fatigue failure due to trafficking and is and entirely separate
phenomenon from the initial cracking due to environmental changes.
Cracks in stabilized layers used at capping and sub-base level are unlikely to cause significant
problems but at base level the cracks may be reflected through the surfacing. The existence of
cracks in a road surface may assumed to indicate need for remedial action. The consequences of
not doing so, may range from no problems at all to loss of interlock or to eventual failure when the
stabilized layer has been reduced to unconnected blocks. Cracks may also permit ingress of water
leading to weathering of materials at crack faces, de-bonding between pavement layers, or
deterioration of moisture-susceptible layers beneath the stabilized layer.
12.7.3 Primary Cracking
Cracks appear in cement-stabilized materials as a result of shrinkage and temperature
fluctuations. The initial crack pattern is dependent on the early strength of the material and the
properties of the material used. Materials which have low strength, normally also contain a higher
proportion of plastic fines. The stabilized materials with lower strength and with high proportion of
plastic fines have frequent but narrow cracks. Whether or not these frequent but fine cracks prove
to be a problem depends to a large extent on the mechanical interlock at the face of the cracks. It
the interlock is good the material performs satisfactory and the cracks are sufficiently fine for them
not to be reflected through the pavement layer above. However, the lower strengths of these
stabilized materials mean that they are generally only suitable for use in the lower layers of the
road where cracking is less of problem anyway.
On the other hand, stabilized materials with high strength criteria and which have little, if any,
plastic fines have fewer but wide cracks. These cracks are often wide enough for them to be
reflected though the surface. In order to restrain the propagation of lateral reflective cracks, such
materials therefore have to be covered with a greater thickness of construction material than
would otherwise be required.
The temperature at which the material is laid also plays a part in the type of crack pattern that is
produced. Layers placed in cooler weather tend to develop fewer and narrower cracks as there is
less thermal shrinkage. The stabilized layer may subsequently be in compression, apart perhaps
from prolonged cold spells, so that cracks remain closed with good load transfer. Fewer cracks
develop when the temperature difference between day and night during construction is not large,
as thermal warping is reduced.
12.7.4 Traffic Associated Cracks
Quite separately and much more importantly than the primary transverse cracks, cracks may
appear is stabilized bases of inadequate strength or inadequate construction thickness in relation
to the traffic and the sub-grade strength. Such cracking takes the form of “map” cracking which, in
extreme cases, cause the stabilized material to deteriorate into small slabs with poor load transfer.
Once started, deterioration is likely to continue until the stabilized base becomes little more
effective that granular sub-base.
When extensive cracking has developed as a result of the combined action of free water and
traffic, then it other results in the “pumping” to the surface of fine material from the underlying
pavement layers where it is deposited in the cracks. The fines discolour the surface along the
cracks making them clearly visible.

Unlike the primary cracking, the appearance of traffic-associated cracks is not inevitable. It should
not occur if the road pavement has been properly designed to take account of the traffic likely to
be encountered during the design life of the road.
12.7.5 Durability of Stabilized Materials
The failure of stabilized materials by disintegration into a loose mass is not common. It is most
likely to be due to deficiency either in the amount of stabilizer, deficiency in the quality of the
stabilizer, or deficient compaction or curing. These problems should not occur if a good standard of
preliminary testing for suitability and of quality control are maintained.
It is reported that the most common type of failure of stabilized layers is the peeling-off of surface
dressings from stabilized layers. This is usually due to failure of top of the layers itself rather than
any of the shortcoming of the surface dressing. The surface of the layer tends to disintegrate
under traffic, the most likely cause of which is considered to be as a result of overstressing of the
surface layer during the compaction of the stabilized material at the time of construction. This
induces a series of shallow shear of shallow shear planes in the surface layer and result is a sharp
failing-off density of the material towards the upper surface. Overstressing is most prevalent with
uniformly graded non-cohesive sands. It can be avoided if special care is taken with the
compaction and if towed vibrating rollers are used.
A survey of know causes of lack of durability of stabilized layers confirmed that the most common
problem was surface disintegration of the primed layer during construction and scabbing of the
seal in service due to an inadequate bond with the stabilized material. These problems are a result
of inadequate compaction and curing and are more likely to occur in hot, dry climates. Apart from
the problem of surface disintegration, long-term durability may also be impaired by the effects of
sulphates and by carbonation.
12.7.6 Control of Reflective Cracking in Cement Stabilized Pavements
Although the potential exists for reflection cracking when a cement-stabilized base is used in a
pavement structure, proper construction and design techniques can minimize the potential that the
pavement will be adversely affected. Proper construction practices to minimize drying, pre-
cracking soon after construction, and designing for stress relief are all valid methods that will
reduce or eliminate the formation of reflection cracks in cement-stabilized bases.
There are several factors as discussed in the previous chapter, which contribute to the cracking in
a cement-stabilized base/sub-base. With regard to material characteristics, the type of soil,
cement content, degree of compaction and curing, and temperature and moisture changes directly
influence the degree of shrinkage.
There are a number of preventative measures and design concepts that can be sued to minimize
shrinkage cracking in the cement-stabilized base, and to reduce the potential, that base cracks will
reflect through the asphalt surface. Methods of controlling reflective cracking include proper
construction and curing of the stabilized base, reduction of cracks size through the use of “pre-
cracking”, and relief of stress concentrations through the use of flexible layers in the pavement
structure.
A cement-stabilized base provides excellent support for asphalt surfaces. The stabilized base
material is stronger, more uniform and more water resistant that an un-stabilized base. Loads are
distributed over a larger area and stresses in the subgrade are reduced. However, cement-
stabilized bases can also be the source of shrinkage cracks in the stabilized based layer, which can
reflect through the asphalt surface. The cracks that develop are not the result of a structural
deficiency, but rather a natural characteristic of cement-stabilized bases. The surface cracks tend
to follow the same patter as the cracks in the base, and referred to as “reflection” cracks.

In most cases, reflection cracks are narrow (less than 3 mm) and will not adversely affect the
performance of the pavement. However, wider cracks can result in rough riding surface and
deterioration of the pavement. The wide cracks create an environment for water infiltration and
subsequent pumping of the underlying sub grade.
Several factors contribute to the cracking and crack spacing in a cement stabilized base which
include material characteristics, construction procedure, traffic and restraint imposed on the base
by the subgrade. With regard to material characteristics the primary cause of cracking is due to
drying shrinkage of the cement stabilized base. The degree of drying shrinkage is affected by the
type of soil, degree of compaction and curing, cement content, temperatures and moisture
changes.
Cement stabilized fine grained soils e.g. clays exhibit greater shrinkage than cement stabilized
granular soils. Although stabilized clay soils develop higher total shrinkage than granular soils, the
cracks are typically finer and more closely spaced other of hairline variety spaced 0.6 to 3.0 m
apart. The granular soils generally produce less shrinkage but develop larger cracks typically
spaced at 3.0 to 6.0 m apart.
Fine grain grained soils have large surface area than granular soils and typically require higher
moisture content for compaction purposes. In addition, cement content for fine grained soils are
generally 2 to 5 percent higher than granular soils in order to achieve adequate durability and
strength. Both these factor contribute to high moisture contents for stabilized fine grained soils
and consequently higher drying shrinkage.
The effect of compaction on shrinkage characteristics of cement stabilized material plays an
important role. A well compacted mixture exhibits reduced shrinkage potential, because the
soil/aggregates particles are packed tightly together resulting in reduced voids. It has been
reported that compacting cement stabilized soil at modified proctor effort, reduces shrinkage
significantly as compared to stabilized soil compacted standard proctor density. The reason for the
same can be attributed to the fact that the optimum moisture contents at modified proctor
compaction are typically less that at standard proctor compaction which helps to reduce shrinkage.
The least amount of shrinkage is obtained for the stabilized material at the highest density and
lowest moisture content.
Cement hydration contributes less to shrinkage than does many other factors. In fact, for soils
that exhibit volume change without cement, increasing cement will decrease total shrinkage.
However, excessive amounts of cement can exacerbate cracking in two ways: First, increased
cement content cause greater consumption of water during hydration, thus increasing drying
shrinkage. Also, higher cement levels cause higher rigidity and excessive strength (both tensile
and compressive).
Methods of controlling reflective cracking basically fall into the two categories:
Pre-cracking
Providing for stress relief at the base-surface interface
Pre-Cracking: Minimizing crack width with proper construction and curing procedures, as
discussed in the previous sections, will eliminate much of the potential for wide cracks. Another
method to reduce crack width is a relatively new procedure called “pre-cracking”, where hundreds
of tiny micro-cracks develop instead of single transverse cracks. The method has been successfully
tried on several projects in the United States. The procedure involves several passes of a large
vibratory roller over the cement-stabilized base one to two days after final compaction. This
introduces a network of closely spaced hairline cracks into the cement-stabilized material, which
acts to relieve the shrinkage stresses in the early stages of curing, and provides a crack pattern
that will minimize the development of wide shrinkage cracks. In addition, since the pre-cracking is

Signature of Contractor For Accepting Officer
performed shortly after placement, the “micro-cracking” will not impact the pavement‟s overall
structural capacity as the cracks will heal and the cement-stabilized material will continue to gain
strength with time.
Stress Relief: Another method of reducing the potential for reflection cracking is to relieve
the stress concentrations that result from cracks in the cement-stabilized base. The following three
methods have been successfully used to reduce the stresses that cause reflection cracks:
1) A bituminous surface treatment (chip seal) between the stabilized base and the asphalt
surface. The additional flexibility of the surface treatment layer will help to reduce stress
concentrations. This surface treatment also provides an excellent temporary surface during
construction for traffic control.
2) A geotextile between the stabilized base and surface, or between the asphalt binder and
wearing courses. Similar to the surface, treatment, the geotextile provides flexibility and
acts to intercept cracks without letting them pass through the material.
3) A 50 mm to 100 mm layer of unbound granular material between the stabilized base
layer and the asphalt surface. This use of “sandwich” or “inverted” pavement design adds
additional structure to the pavement, and will prevent the propagation of cracks through to
the surface layer.
