Original Abstract

Asphalt concrete is a traditional material used for constructions of upstream sealing of reservoir dams, particularly in upper reservoirs of pumped storage hydroelectric plants. The asphalt layer is often exposed to significant fluctuations of temperature caused, for example, by heating the facing from the sun and by its subsequent rapid cooling by water during reservoir periodical filling. To better understand the physical phenomena and behaviour of the facing in terms of vapour diffusion, the state of stress, etc., it is necessary to know temperature phenomena in the asphalt facing. This paper describes the measurement of temperature in the asphalt facing of the Dlouhe Strane pumped storage hydroelectric plant and its evaluation. The results of measurement were used for the calibration of a mathematical model of heat flow in the asphalt facing. Numerical simulation for selected load scenarios enabled the temperature phenomena that take place in the construction of the asphalt-concrete facing to be quantified. The calculations were made using a one-dimensional model of heat flow; the numerical solution was made using the finite difference method. The results can serve as a starting base for the subsequent description of physical constructional-technical phenomena influencing the service life of the asphalt-concrete facing
