An overpass is being built over the PVI of an existing equal tangent sag curve. The sag curve has a 70 mi/h design speed, and G1 = -6%, G2 = +3%. Determine the minimum necessary clearance height of the overpass and the resultant elevation of the bottom of the overpass over the PVI. (ignore the cross-sectional width of the overpass).
Would a 30 slot stainless steel screen (2.0 m long; located at the bottom of the well) have sufficient collapse strength for this application?
Determine, for the crest and sag vertical curves required, the stationing and elevation of the PVCs and PVTs given that the PVC of the crest curve(on westernmost level highway section) is at station 0+00 and elevation 100 ft.
A soil sample with a water content of 14.5% and unit weight of 128.2 lb/cu. ft. was dried to a unit weight of 118.8 lb/cu. ft. without changing its void ratio. What is its new water content (in %)?
