The elastic modulus of an asphalt concrete pavement is strongly influenced by the temperature of the layer. This is due to the rheological behaviour of the binder present in asphalt concrete layer.

Abstract

The elastic modulus of an asphalt concrete pavement is strongly influenced by the temperature of the layer. This is due to the rheological behaviour of the binder present in asphalt concrete layer. For this reason it has a great importance knowing the thermal state of the layer for comparing the values of the elastic modulus of pavements in different climatic conditions. In the case of deflection measurements this is especially necessary. Basing on these considerations, a predictive model of the temperatures inside the pavement has been developed. It uses as input the temperature at the surface as is recorded during FWD tests. The model is founded on a database of temperatures measured at surface and at different depths (10, 15, 20, 30 cm) of an asphalt concrete pavement during three years.
