Structural Behavior of Cast In Situ Concrete Block Pavement

This paper describes the findings of a study carried out for evaluating the performance of cast in situ concrete block pavements for low volume roads. Concrete is filled up into a formwork of cells 150 mm×150 mm×100 mm made up of thin plastic sheets and compacted to form flexible interlocked concrete blocks. Details of a laboratory investigation on the proportioning of mixes and the evaluation of the strength of different mixes are presented. Cast in situ block pavements were constructed and tested in an accelerated pavement test facility. It was found that the blocks became interlocked and that the block pavement displayed a very little amount of rutting along the wheel path. A falling weight deflectometer test indicated that the equivalent elastic modulus of cast in situ concrete blocks was over 2,500 MPa. An example of pavement design using cast in situ concrete blocks is presented.
