A general quasi-static computational procedure is established to evaluate stresses and strainsinduced in the viscoelastic ﬂexible pavement bymoving trafﬁc. The procedure is based on superposition principle and is computationally favourable, as itrequires only reduced incremental problem to besolved numerically. The impact of trafﬁc speed anddensity on the mechanical response of ﬂexible pavement is examined numerically. Results relevant fortwo major modes of pavement’s distress, i.e. crackingand rutting, are reported. It is shown that the state-ofpractice layered elastic analysis used in pavementdesign is unable to capture several important qualitative and quantitative aspects of pavements response.
