ICBP tolerates higher deflections without structural failure and will not be affected by thermal expansion or contraction.Good quality of blocks ensures durability of pavements, when constructed to specifications.Mass production under factory conditions ensures availability of blocks having consistent quality and high dimensional accuracy.There are many distinct features of ICBP as compared to the conventional methods of pavement construction and hence make it a suitable option for application in the specified areas. Many number of such applications for light, medium, heavy and very heavy traffic conditions are currently in practice around the world. 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. The block joints are filled using suitable fine material. 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).ĬBP/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. During the past five decades, the block shape has steadily evolved from non-interlocking to partially interlocking to fully interlocking to multiply interlocking shapes. These blocks were rectangular in shape and had more or less the same size as the bricks. The paper dwells upon material, construction and laying of concrete block pavement as a new approach in construction of pavement using Interlocking Concrete Paver Blocks.Ĭoncrete 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. but now being adopted extensively in different uses where the conventional construction of pavement using hot bituminous mix or cement concrete technology is not feasible or desirable. ICBP technology has been introduced in India in construction, a decade ago, for specific requirement viz. ![]() Interlocking Concrete Block Pavement (ICBP) has been extensively used in a number of countries for quite sometime as a specialized problem-solving technique for providing pavement in areas where conventional types of construction are less durable due to many operational and environmental constraints. ![]() ![]() Sharma, Scientist "F" Central Road Research Institute, New Delhi
