Fantastic news! We've Found the answer you've been seeking!
Question:
The CBR values, obtained from laboratory test, at 100 intervals on the centerline of a B category road (i.e. TRH4 class) section in wet region (n <2) are given:
5, 7 ,6 ,7 ,7,8 ,5 ,14 ,12 ,10 ,13 ,15 ,22 ,25 ,22 ,18.
1. Delineate the subgrade into uniform sections.
2. Compute subgrade design CBR for uniform sections (show detailed calculations).
3. Draw neat, labelled sketches to show subgrade design for each delineated area.
4. Explain necessary measure to be taken if a 1.0 m long isolated rock exists on the surface at chainage 1+ 250.
