This is the overview of the selected site which was in lucknow. We give the solution of the waterlockege on the the earthen road and provide the suitable method for road construction work on this particular portion. No other type roads are not survive long as compare to rigid pavement.

3. INTRODUCTION
As the name implies, rigid pavements are rigid i.e., they do not flex
much under loading like flexible pavements. It is constructed using
cement concrete. In this case, the load carrying capacity is mainly due
to the rigidity and high modulus of elasticity of the slab (slab action).
Rigid pavements are those which possess note worthy flexural
strength or flexural rigidity. The stresses are not transferred from grain
to grain to the lower layers as in the case of flexible pavement layers.
The rigid pavements are made of Portland cement concrete-either
plain, reinforced or prestressed concrete.
The rigid pavement has the slab action and is capable of transmitting
the wheel load stresses through a wider area below. As the rigid
pavement slab has tensile strength, tensile stresses are developed due
to the bending of the slab under wheel load and temperature

4. OBJECTIVE OF RIGID PAVEMENT
The surface of the roadway should be stable and non-yielding, to allow the
heavy wheel loads of road traffic to move with least possible rolling resistance.
The road surface should also be even along the longitudinal profile to enable
the fast vehicles to move safely and comfortably at the design speed. In order to
provide a stable and even surface for the traffic, the roadway is provided with a
suitably designed and constructed pavement structure. Thus a pavement
consisting of a few layers of pavement materials is constructed over a prepared
soil subgrade to serve as a carriageway. The pavement carries the wheel loads
and transfer the load stresses through a wider area on the soil subgrade below.
Thus the stresses transferred to the subgrade soil through the pavement layers
are considerably lower than the contact pressure or compressive stresses under
the wheel load on the pavement surface. It is always desirable to construct the
pavement well above the maximum level of the ground water to keep the
subgrade relatively dry even during monsoons.

5. WHERE IS RIGID PAVEMENT PROVIDED
Rigid pavements are usually provided when road stretch is
subjected to adverse conditions.
• Very heavy rainfall
• Poor soil conditions
• poor drainage
• Extreme climatic conditions
• Combinations of some of these conditions which may lead
to development of cracks in pavements.

6. COMPONENT OF RIGID PAVEMENT

7. MATERIALS USED FOR CONSTRUCTION
PORTLAND CEMENT :
The type of cement that may be used for the preparation of PQC and
construction of cement concrete road construction pavement are:-
(i) Ordinary Portland cement of 43 Grade.
(i) Ordinary Portland 53 Grade.
(ii) Portland Pozzolana cement with fly ash content up to 20% by weight.
(iv) Portland slag cement.
However most commonly used cement for the
cement concrete road construction is ordinary Portland cement of 43 Grade.

8. MATERIALS USED FOR CONSTRUCTION
COARSE AGGREGATE VALUES OF CEMENT CONCRETE ROAD
The coarse aggregate that is used for PQC of cement concrete road
construction should fulfil the following requirements apart from
this the maximum size being limited to 31.5 mm.
FINE AGGREGATES USED IN ROAD CONSTRUCTION
Fine aggregate consists of clean natural sand or crushed stone
sand or a combination of both. The fine aggregate shall be
well graded, with 100 percent passing 10 mm sieve.

9. DESIRABLE LIMITS OF IMPORTANT PROPERTIES

10. TYPES OF RIGID PAVEMENT
• Jointed Plain Concrete Pavement (JPCP)
(does not use any reinforcing steel)
• Jointed Reinforced Concrete Pavement (JRCP)
(Reinforcing steel placed at mid height and
discontinued
at the joints.)
• Continuously Reinforced Concrete Pavement (CRCP)
(This method is very costly and generally not used in
India.

11. JOINTS IN RIGID PAVEMENT
Joints are the discontinuities in the concrete pavement slab, and
help to release
stresses due to temperature variation, subgrade moisture
variation, shrinkage of
concrete etc.
There are various types of joints in concrete pavement –
1. Longitudinal joints(parallel to traffic flow)
2. Transverse joints(perpendicular to traffic flow)
• Contraction joints
• Expansion joints
• Construction joints
