CONSTRUCTION OF INTERLOCKING CONCRETE BLOCK PAVEMENTS

This paper aims at creating an awareness of some of the construction areas which need to be considered and catered for when constructing an interlocking concrete block pavement. The sequence of operation in the construction of a block pavement is described in detail, including site preparation, subgrade preparation, sub-base placing and preparation, placing of the bedding sand, the block laying and pavement compaction by surface vibration. Some of the problems that could be encountered, and techniques for avoiding or correcting these problems are described. Some emphasis is given to keeping moisture content of the bedding sand as constant as possible, as variation in moisture content will cause variation in the compacted thickness of the sand. Setting out is highlighted as one of the most important aspects of block laying, particularly provision of string lines to set the pavement out and regular checking of alignment of the blocks to the string line. Caution with joint width, the need to proceed uphill rather than down and to place edge blocks prior to compaction, and to complete initial compaction prior to sand being swept into joints are all emphasised.
