Influence of temperature distribution on the design of pavement structures

Abstract

The bearing capacity of asphalt pavement structures is not constant due to the continuous change of temperature, and the importance of temperature change varies layer by layer. In the present article we reveal to what extent temperature change influences cumulated fatigue with the application of detailed pavement structure models and which seasons and parts of the day are significant in terms of fatigue. The pavement structure models were set up on the basis of stiffness tests performed in laboratory and on the data supplied by a temperature detector placed into a pavement structure. The set of data contains the results of measurements of one year with the measurement frequency of 10 minutes.
