A natural way to test the quality of a pavement is to send signals with different frequencies through the pavement and compare the results with the signals passing through an ideal pavement. For this comparison, we must determine how, for the corresponding mixture, the elasticity E de-pends on the frequency f in the range from 0.1 to 105 Hz. It is very expensive to perform measurements in high fre-quency area (above 20 Hz). To avoid these measurements, we can use the fact that for most of these mixtures, when we change a temperature, the new dependence changes simply by scaling. Thus, instead of performing expensive measure-ments for different frequencies, we can measure the depen
