The construction of arch bridges has become uncommon lately, although it is clear that the compressive bearing capacity of cheap building materials is generally very high. The main reason for this is definitely the high price of shuttering system that is in present use. The system presented in this paper demonstrates a new relationship between the price of shuttering and the structure itself. The basic element is a very thin prestressed, post arch-shaped plate, made of polymer modified SFRC. Such elements are used as shuttering systems during the first stage of construction while later they become a part of a general bearing system. This brings about entirely new possibilities for the applications of arch constructions, especially regarding the actual known characteristics of high performance concrete. Keywords: Arch constructions, Prestressed concrete, Steel fibre reinforced concrete (SFRC), Polymer modified concrete (PMC), High performance concrete (HPC).
