The problem of road traffic induced vibrations is gaining wider attention among people and transport engineers as vibrations transmitted by vehicular traffic are often considered to be liable for minor damages and for nuisance in building close to major road section in urban areas. Among the different mitigation approaches, the use of an anti-vibrating pavement seems the most feasible, in view of the various economic and functional constraints on site. Early examples of anti-vibrating pavements in Italy date back to the beginning of the seventies when Colonnetti designed the first anti-vibrating road superstructure in order to mitigate the vibration level in Villa Farnesina induced by traffic traveling along the LungoTevere road. Analysis of the scarce literature related to these road superstructures has highlighted that the effectiveness of a particular solution seems to be mainly verified by means of an experimental approach, theoretical models developed are often very rough and simple; furthermore, the design of pavement in view of its serviceability, is often neglected. Following these remarks, a new methodological approach to the design of an anti-vibrating pavement is proposed, according to this which, several pavement layouts have been initially checked against conventional pave-ment design criteria and afterwards their effectiveness in attenuating vibration has been evaluated by means of an “ad hoc” mathematical model that can be conceptually divided into two main sub-models: a vibration generation model and a propagation model. In the generation sub-model the dynamic interaction between heavy vehicle and road surface irregularity is tackled. Vehicle is represented by means of a discrete dynamic system (a typical “half car”, four-degree-of freedom model), whereas the road profile is described in a deterministic manner. Input parameters in this phase are: vehicle speed, vehicle inertial and mechanical properties, and road profile. Output of this phase are the time histories of dynamic overloads transmitted by the front and rear axle to the road surface. In the propagation sub-model the transmission of vibration induced by the heavy vehicles up to a specific distance from the source is analyzed by means of a three-dimensional FEM model.
