This paper explains briefly how to produce the modern equivalent of a traditional masonry arch bridge using mass concrete with plastic inclusions. It discusses the results obtained from field tests of one such bridge-Monk New Bridge. The field test highlighted that the nature of load transfer in the vicinity of the inclusion was not well understood. A prism model of an inclusion concrete unit was therefore devised and subjected to different line loads to study the load transfer phenomenon. In parallel with the laboratory tests programme, finite element modeling was conducted using ANSYS 5.3. The preliminary findings of the research programme are presented in this paper and conclusions are drawn that will aid the designer.
