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.

Abstract

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. This complex topic that can be usually split in several phases: generation of vibrations, transmission through pavement layer and underlying soils, and reception in the building. 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. In this paper a methodological approach for the design of an anti-vibrating pavement is proposed. Several pavement layouts have been initially checked against conventional pavement design criteria and afterwards their effectiveness in attenuating vibration has been evaluated by means of an “ad hoc” mathematical model. Results of numerical simulations seems to indicate that the attenuation properties are greatly affected by on-site soils, although the asphaltic concrete pavements examined show a moderate efficiency in reducing vibration level.
