Reclaimed asphalt pavement is used as an aggregate in the cold recycling of asphalt paving mixtures. The more common method involves a process in which the asphalt pavement is recycled in-place (cold in-place recycling), CIPR. Where the Journal of Engineering Research (University of Tripoli) Issue (20) September 2014 67 reclaimed asphalt pavement is combined without heat with foamed bitumen and...

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 Bo...

Warm Mix Asphalt (WMA) is a set of technologies that uses additives to reduce binder viscosity and increase mixture workability, which provides complete coating aggregates at lower temperatures around 100 °C 130 °C. Organic wax or Sasobit one the can be used for this purpose. It reduces melting point wax, allows production asphalt mixes temperatures. This attempt proposes new relationships elas...

In order to produce high-viscosity and high-toughness asphalt for ultra-thin overlays, the conventional cement was modified with high-content SBS micro carbon fiber (MCF). The performances of were studied by tests penetration, softening point, ductility, kinematic viscosity, multiple stress creep recovery (MSCR), dynamic shear rheometer (DSR) bending beam (BBR). Mixture properties rutting, low-...
