An asphalt processing system is formed from a heating chamber, a transfer system and an induction heating system. A plurality of paddles, conveyor flights, or conveyor belts having a U-shaped blade move the asphalt through the system while concurrently mixing the material to ensure consistent temperatures through the asphalt cement. The asphalt is heating using one or more induction heating systems to quickly heat the asphalt to between 300° F. and 350° F. The system can include a convection system designed to collect air from the heating chamber, further heat it, and recirculate the air to enhance the asphalt heating. A water condenser can be employed to remove moisture during air recirculation, reducing moisture content in the asphalt cement. The asphalt cement is optionally then modified by addition of one or more rejuvenation oils. This system is particularly useful for recycled asphalt pavement, but can be used for all asphalt products.

The invention relates to a construction block comprising petroleum coke and at least one binder, and having a vertical and/or horizontal water permeability of less than or equal to 0.005 mm/s.

The invention also relates to the use of a composition comprising petroleum coke and at least one binder, for the manufacture of a construction block.

The present technology relates to an anti-stripping agent for an asphalt mixture, which includes a refined slowly-cooled slag obtained by processing slag, generated in ironmaking and steelmaking processes, using a specific method, and to a method for preparing the same, an asphalt mixture including the same, and a method for preparing the asphalt mixture. The refined slowly-cooled slag may include 55 to 65 mass % of CaO, 5 to 10 mass % of SiO.sub.2, 1 to 5 mass % of Al.sub.2O.sub.3, and 1 to 5 mass % of MgO.
