Concrete paver blocks were first introduced in Holland in the fifties as replacement of paver bricks which had become scarce due to the post-war building construction boom. These blocks were rectangular in shape and had more or less the same size as the bricks. During the past five decades, the block shape has steadily evolved from non-interlocking to partially interlocking to fully interlocking to multiply interlocking shapes. Consequently, the pavements in which non-interlocking blocks are used are designated as Concrete Block Pavement (CBP) or non-interlocking CBP, and those in which partially, fully or multiply interlocking blocks are used are designated as 'Interlocking Concrete Block Pavement (ICBP).
CBP /ICBP consists of a surface layer of small-element, solid un-reinforced pre-cast concrete paver blocks laid on a thin, compacted bedding material which is constructed over a properly profiled base course and is bounded by edge restraints/kerb stones. The block joints are filled using suitable fine material. A properly designed and constructed CBP/ ICBP gives excellent performance when applied at locations where conventional systems have lower service life due to a number of geological, traffic, environmental and operational constraints [1-8]. Many number of such applications for light, medium, heavy and very heavy traffic conditions are currently in practice around the world.

| Advantages of Paver Blocks: |
1. Ease to access to underground services and the fact that the blocks can be reused to restore the pavement to its original profile.
2. The laying technique is suited to unskilled labor provided they have adequate supervision.
3. The product is available in a wide variety of shapes and colors.
4. Concrete’ blocks have good durability and wearing resistance and are unaffected by oil and other toxic substances.
5. Adequate skid resistance for vehicles and anti-slip element for pedestrian areas.
6. Immediate use after laying and large life spans.
7. Provides permanent road markings.
8. Thermal movement minimized by large number of block interfaces and by load carrying capability under deflected conditions.
9. The maintenance requirements are low.
10. Service can be accessed or installed with relative ease by removal and replacement of pavers.
11. Reinstatement of the pavement does not leave obvious patches.
