Theoretical study of the thermal behavior of a supple road structure in frequency dynamic modulation under illumination and shade: determination of the temperatures and the flow densities in the interfaces

Abstract

The determination of the mechanical parameters for the sizing of a road allows, according to the traffic to choose the minimal thickness for various layers. These parameters vary according to the climatic measurement in strong thermal stress zone (illumination) or in of low thermal stress zone (shade) In this work, a theatrical study on the temperature variation and the flow density determination method for every interface of the road structure is proposed in frequency dynamic modulation. This method highlights the influence of the climatic parameters such as the thermal exchange coefficient by radiation and the thermal exchange coefficient by convection.
