摘要：

Among others, the long term durability of road pavements is influenced by the time gap between the laying process and the opening to traffic. Here, in this project a rather simple method for the estimation of the time for opening the pavement to traffic after the laying process is discussed. Therefore in the first part of the paper a technique for the measurement of the mechanical input impedance is introduced. On the basis of this measurement the Young's modulus is estimated at 5 Hz and 20 degrees C by use of the temperature/frequency equivalence. In the second part of the project the method has been applied to five new built German pavements. Moreover, by applying a first rough assumption for the setting of asphalts the time for opening the pavements to traffic has been estimated.
