Module Dynamique et Angle de Phase des Enrobes C-LTPP

摘要

Pavement design based on a mechanistic-empirical method requires the mechanical properties of pavement materials. The dynamic modulus and the phase angle of 11 asphalt mixes sampled at 11 C-LTPP sites were characterized at different frequencies and temperatures with a cyclic three point load flexure equipment. The dynamic modulus master curves are modeled as a function of frequency and temperature according to the frequency-temperature equivalence principal. The phase angle Black curves are modeled as a function of dynamic modulus. A general master curve and Black curve were developed based on the average of the individual curves.
