Remove Existing Pavement from GEOPAK SS2 XS

I have a set of cross-sections from which I would like to quantify pavement removal volumes (in addition to the normal cut/fill and agg volumes). The end areas of unsuitable material below my necessary cut are not being accounted for as removals. My understanding is that if I use excavation limit lines ALL unsuitable material between excavation limit lines will be removed. This is not happening.
 
Below is a screen shot showing what area I am referring to.

Here is a piece of my input file that defines the existing pavement:

Existing Unsuitable Material     /* Existing Asphalt removal */
soil type = INP_ASPH
roadway exc mult factor = 1.000000
subsoil exc mult factor = 1.000000
fill mult factor = 1.000000
type = line, line_string
lvname = P_E_XS_pave inp
co = 6

Existing Unsuitable Material      /* Existing Concrete removal */
soil type = INP_CONC
roadway exc mult factor = 1.000000
subsoil exc mult factor = 1.000000
fill mult factor = 1.000000
type = line, line_string
lvname = P_E_XS_pave inp
CO = 4

Excavation Limit
type = line
lvname = P_XS_ex lim

I tried running this WITH and WITHOUT “Calculate Only Between Excavation Limits”.  When I ran it WITHOUT, EW processed completely, but ALL end areas were 0.00.

Here is another shot without earthwork shapes:

Ideally this is what I am trying to do:

In our specs we pay for pavement removal as a separate item.  I have always been “manually” deducting the volume of pavement removal from the cut volume.  An even better solution would be to have GEOPAK calculate this automatically using the following scenario:

 

  1. When existing pavement (to be removed) is ABOVE the proposed subgrade line deduct from cut volumes.  THIS WORKS.

  2. When existing pavement (to be removed) is BELOW the proposed subgrade line include as fill (to backfill the void left by removing the pavement, but below the subgrade line).  NOT WORKING

  3. Combination of both if existing pavement straddles the subgrade line.
