  Thickened  edge  should  be  1.25  the  slab  thickness    Should  taper  to  the  slab  thickness  over  a  distance  of  3  ft  

  Odd-­‐shaped  slabs    Slabs  that  are  not  rectangular    Rectangular  slabs  with  width-­‐to-­‐length  ratios  that  exceed  1.25  

  Odd-­‐shaped  slabs  should  be  reinforced  with  0.05%  steel  in  both  directions  

  Used  only  for  non-­‐jet  aircraft,  weights  of  12,500  lbs  or  less  

  Aggregate  is  added  to  the  soil  to  provide  stability  to  the  surface  

  Enough  aggregate  for  stability  with  enough  soil  to  grow  grass
