その他の書誌記述:In recent years, different test methods and procedures have been developed to evaluate the rheological properties of asphalt materials, some of which have been incorporated in design methodologies and standards in Mexico. However, the correct determination of mechanical properties of asphalt mix involves complex evaluations and the need for other areas of knowledge as metrology, instrumentation and data processing, combined with a clear understanding of the mechanical behavior of a viscoelastic material. This is the case for the dynamic modulus test, which aims to evaluate the linear viscoelastic properties of the asphalt mixture by determining two mechanical parameters, the dynamic or complex module (|E*|) and the phase angle (δ). The present article illustrates the evaluation of the viscoelastic properties of an asphalt mixture and the analysis of the data obtained in tests. Indicating some of the general errors in the conduction of the test and to justify the test sequence proposed by the IMT regarding the AASHTO T 342 Standard, which does not alter the identification of the linear viscoelastic properties of the asphalt mixture.
