Abstract

This research evaluates the mineral filler content and type influence, and the binder type, on the rheological behavior throughout the temperature range in which the pavement is subject in the service life. Tests were conducted under oscillatory shear, the dynamic shear rheometer (DSR) to characterize the complex modulus (G*) and the phase angle (δ); and in the bending beam rheometer (BBR) to characterize the low temperature properties of the mastics through the flexural creep stiffness (S(t)) and the m-value. The factors that influence G* and δ are the loading frequency and the type of binder, and the filler type and amount only influence the mastic
elasticity, and the stiffness only when evaluate the hydrated lime results. The BBR results are significantly affected by the filler amount and type of binder.
