TLDR
An efficient pavement performance analysis framework is developed by combining the ideas of time-scale separation and Fourier transform-based layered analysis, which can capture the effects of viscoelasticity, temperature, temperature (thermal stresses and changes in visCoelastic properties) and the moving nature of the traffic load.Abstract:
An efficient pavement performance analysis framework is developed by combining the ideas of time-scale separation and Fourier transform-based layered analysis. First, utilizing the vast difference in time scales associated with temperature and traffic load variations, the number of stress analysis runs are reduced from several million to a few dozen. Second, the computational cost of the pavement stress analysis is reduced significantly by using Fourier transform-based analysis. The resulting pavement performance prediction tool, named the layered viscoelastic continuum damage (LVECD) program, can capture the effects of viscoelasticity, temperature (thermal stresses and changes in viscoelastic properties) and the moving nature of the traffic load. The efficiency of the LVECD program is shown through 20-year pavement simulations.read more
