Summary:
An experimental section was constructed using wet process asphalt-rubber.  The section is an overlay over a flexible
pavement and includes a control section using conventional HMA.  Conclusions are that asphalt-rubber blending is
completed.  Mix designs are included.  Cost increases of 50 – 60% over conventional HMA are expected and tire disposal
costs were calculated to be $31.67 per tire.  Performance evaluations are planned.  See RPA_A1406.pdf  for more
information.
