Hello team,
In my design i have situation like, overlay thickness of 50mm on existing carriageway and widening on both side with BC=40mm, DBM 60mm, WMM=250mm , GSB=200mm, subgrade=500mm is to be provide.
while design pavement layers with above said pavement composition, i need to limit my existing road strings with 50mm. But i am unable to get the existing CW strings to limit my ends for overlay thickness.
Kindly suggest me the procedure to perform the said problem. As of now i am trying with <Dsign<Pavement and Subgrade design(to existing pavement) option.
If any video for this procedure please do share.
Thanks in advance
