Claim Text:
1. A device for monitoring aging of a viscoelastic material, comprising: a sample-carrier having a chamber for receiving a sample of said viscoelastic material, wherein the sample-carrier is shaped and dimensioned so as to be placed in a vicinity of a mass of material of the same kind as said sample which is placed in said chamber, said chamber is provided with one or more windows for putting said sample into contact with the same environment as the mass of material; a vibration source in the form of a piezoelectric actuator, coupled to a wall of said chamber; a vibration sensor configured to measure compression or traction/compression coupled to another wall of said chamber, the vibration sensor being configured to be connectable to a calculation device for determining at least one parameter representative of an aging state of the sample from a signal communicated by said vibration sensor; and load-applying means for applying initial mechanical loading in order to press the two above-mentioned walls of said chamber against the sample.
