Calculation of the equivalent temperature of pavement structures

Abstract

Due to the difficulties of the description of temperature variation, rating of asphalt pavement structures respecting fatigue is made on equivalent temperature. In general, equivalent temperature is calculated according to average and weighted air temperature. It is proven, based on processing numerous data provided by the temperature detectors laid in the pavement structures as well as determination of the partial fatigue values, which the present method used to calculate the equivalent temperature results in data losses. Furthermore, it is proven, that pavement structure temperature based on air temperature can be determined only to limited extent. Knowledge of temperature distribution of the pavement structure provides the possibility of more accurate design.
