The influence of traffic moving speed on shakedown limits of flexible pavements

摘要: AbstractShakedown theory is often used to analyse elastic–plastic responses of structures subjected variable or repeated loads. In pavement engineering, it has been predict the maximum admissible load (termed as ‘shakedown limit’) against excessive rutting in flexible pavements. Pavement shakedown analysis, which involves calculation limit, usually utilised elastic stresses induced by a static wheel and therefore neglected any possible dynamic responses. This paper will, for first time, evaluate effect moving on limit pavement. A numerical approach developed based recent lower bound method solving problem. The traffic loads are computed using finite element infinite elements boundaries. Shakedown limits single subgrade layer pavement-subgrade system under at various s...
