On the proposed SS105-18…

On the proposed SS105-18 drawing, the Longitudinal Section indicates a minimum 250 mm of sub-base pavement layers (granular) at the end of the approach slab. Should this 250 mm dimension instead be shown to indicate minimum 250 mm at the point where the thickened section (Section 1) tapers to the 250 mm thick concrete slab section (Section 2)? As shown currently, it could be interpreted to incorrectly such that there is less than 250mm of granular cover on the slab at the transition between Section 1 and Section 2.
