    Abstract: A method of reconstructing a road by selecting a bituminous mixture for repairing a paved surface and re-paving the surface using a hot in-place recycling process. Selection includes adding and mixing various types and amounts of bitumens with a reclaimed sample of the paved surface to form mixtures, compacting the mixtures to form test specimens with air voids within about 1-3% of the air voids of the paved surface or density within 10-20% of the density of the paved surface, and measuring the rheology of the specimens, preferably by a tensile strength procedure. Selecting bitumen content based on the rheology of the tested specimens. Re-paving the surface by milling the surface to a depth of about 1.5-8 inches, mixing the selected bitumen with the milled surface, and paving the surface with the paving mixture thus formed.
