The computer program UPR-PAVI2 was developed to perform the dynamic analysis of a pavement slab or a bridge superstructure loaded with moving vibrating trucks. UPR-PAVI2 can model the soil, slab and truck, considering their stiffness and geometry. This paper presents the theory used by UPR-PAVI2 with emphasis on the modification of the soil-slab-truck stiffness matrix required to consider the truck moving along the slab and the effect of the surface roughness in the force vector.
