This document summarizes a seminar presentation on the design of interlocking concrete block pavement. It describes different types of concrete blocks, how they are composed into pavement of varying thickness depending on traffic levels, and common laying patterns like stretcher bond. It also outlines manual and mechanical laying methods, applications such as footpaths and parking areas, advantages like durability and easy maintenance, and limitations like need for joint filler material. The conclusion states that interlocking concrete block pavement technology provides a durable and sustainable infrastructure alternative to rigid pavement in some applications.

3. INTRODUCTION
Concrete paver blocks were first introduced in the Holland and it
was just like brick.
Interlocking concrete paver is a brick like piece of concrete commonly
used as exterior flooring.
Interlocking concrete pavement consist of surface layer of small
element, solid pre-cast concrete pave block laid on a thin compacted
bedding material which is constructed over a properly profiled base
course.

4. CONCRETE PAVER
 Interlocking concrete
block pavement have
been extensively used
in a number of
countries for quiet
sometimes and give
excellent performance
when applied at the
location.

5.  Type A: Paver blocks with plain
vertical faces, which do not key into
each other when paved in any
pattern.
 Type B: Paver blocks with
alternating plain and curved vertical
faces, which key into each other
along the curve faces, when paved in
any pattern
TYPES OF CONCRETE BLOCK

6.  Type C: Paver blocks having all faces
curved, which key into each other
along all the vertical faces when
paved in any pattern.
 Type D: 'L' and 'X' shaped paver blocks
which have all faces curved and which
key into each other along all the
vertical faces when paved in any
pattern.

7. COMPOSITION OF THE BLOCK PAVEMENT
FOR NON-TRAFFIC PAVEMENT : Such as side walk,
footpath, cycle track, public garden/park, Railway platform,
building premises etc.
• M-25 or M-30 Grade used for Paver Block.
60 mm
Thick
Blocks
20-30 mm
Sand Bed
200 mm Base
Layer
Compacted
Earth

8. FOR LIGHT TRAFFIC PAVEMENT : Such as car parking,
housing colony road, rural road, residential colony road, form
houses etc.
• M-30 or M-35 Grade used for Paver Block
60-80 mm
Thick Block
20-40 mm
Sand Bed
250 mm
Base Layer
250 mm Sub-
Base Layer

9. FOR MEDIUM TRAFFIC PAVEMENT : Such as city streets,
small market road, service station, intersection on low volume
road etc.
• M-35 to M-45 Grade is used for Paver Block.
80-100 mm
Thick Block
20-40 mm
Sand Layer
250 mm
Base Layer
250 mm
Granular
Sub-Base

10. FOR HEAVY TRAFFIC PAVEMENT : Such as bus terminals,
industrial streets, factory floor and pavement, airport
pavement etc.
• M-45 to M-55 Grade is used for Paver Block.
100-120 mm
Thick Block
30-50 mm
Sand Bed
300 mm
Granular
Sub-Base
300 mm
Base
Layer

11. PATTERN OF LAYING OF BLOCK
STRETCHER BOND OR RUNNING
BOND :
A stretcher is block laid flat with its
long narrow side exposed and Running
bond is consisting of all stretchers
HERRINGBONE BOND : A herringbone
pattern can be created by setting the
blocks at either 45 degrees or 90 degrees
to the perpendicular.

12. BASKET WEAVE OR PARQUET BOND : It consists of
multiple horizontal blocks and vertical blocks, resulting in a
square pattern associated with woven baskets.

13. METHODS OF LAYING OF CONCRETE BLOCK
MANUAL METHOD : In the traditional manual method, the
sand is roughly screeded and a skilled worker (called a pavior)
levels the sand and then embeds the block using a hammer.
MECHANICAL METHOD : Mechanical laying requires the
use of specialised equipment for transporting and placing
clusters of paving blocks.
• Mechanised laying must be coordinated with the
manufacturer, so that the blocks are delivered stacked on
pallets in the required pattern

14. APPLICATION OF INTERLOCKING
CONCRETE BLOCK PAVEMENT
Footpath and side-walks
Public parking area
Cycle track
Residential streets
Car parking
Highway rest areas
City streets
Industrial floor

15. ADVANTAGE AND LIMITATION OF
INTERLOCKING CONCRETE BLOCK
PAVEMENT
ADVANTAGES :
• Highly Durable.
• Not much Required Curing.
• Not affected by thermal expansion or contraction.
• Cheap in comparison to Rigid pavement.
• Maintenance is easy and simple.
LIMITATIONS :
• Not suited for higher speed.
• Requires joint filling material sand.
• Care need to be taken to fix the blocks.

16. CONCLUSION
ICBP technology can provide durable and sustainable road
infrastructure where construction and maintenance of
conventional pavements are not cost effective.
ICBP is much cheaper than rigid (concrete) pavement
designed for identical conditions.
Guidelines for use of Interlocking Concrete Block Pavement
and Specification on Paver Blocks are published in Codes and
available with Indian Roads Congress and Bureau of Indian
Standards which are very useful for Indian industries and
highway professions for adoption of block pavement
technology.
