Dynamic Hydraulic Conductivity (Permeability) of Asphalt Pavements
External pressures applied to a saturated pavement pore structure are often dynamic due to the repeated tire loading. Therefore, a dynamic permeability constant is more realistic representation of the response of a pavement pore structure than the Darcy's permeability. To investigate the unsteady (dynamic) fluid flow in asphalt pavements, a 3D fluid flow model was developed using the lattice Boltzmann (LB) method. The model was validated using the well-known closed form solution of oscillating flow through a circular tube. A number of simulations were carried out to calculate the dynamic permeabilities of different asphalt specimens exposed to pulsatile pressures. It was shown that the dynamic permeability of an asphalt pore structure collapse on a single curve for a given frequency, confirming its universal behavior.
