ABSTRACT

The road plate presented in this paper is a universal structure designed for excavation works on building sites and on roads and streets under repair. In cases of failures of urban buried utilities and extended repairs the plate ensures proper operational conditions and vehicular traffic safety. It enables continuous heavy goods vehicle traffic without limiting the carriageway width. This paper presents numerical finite element analysis of the effect of road plate foundation conditions on the durability of the subgrade. The displacements and deformations affecting the durability and longevity of such a system are analysed depending on the location of the load on the plate and the extent to which the plate rests on the excavation shelves. Two extreme cases of plate foundation: 1) foundation on weak subsoil and 2) foundation on flexible road pavement are considered.
