1. A method for predicting at least one physical interaction effect between a tyre and a roadway pavement, the method comprising: using a computer to chart data obtained from a measurement of a surface of the pavement, to produce a real profile of the pavement; using a computer to section the real profile into several strata, each stratum corresponding to an altitude of the real profile; determining at least one law of variation of at least one pavement descriptor based on the real profile, as a function of the altitude; determining an interaction value of each pavement descriptor, for each law of variation; and predicting a value (B) of a physical interaction effect based on an interaction value of at least one pavement descriptor.
