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.
