1. Given are the stations and elevations of a proposed symmetrical parabolic highway curve. POINT ELEVATION (M) STATION 6+075 A 93.60 B 90.00 6+255 (PI) 6+435 C 96.48 Note: Lines AB and BC are the tangent lines of the proposed highway curve. The curve will clear a boulder at Sta. 6+276, and the elevation of the tip of the boulder is 92.65m. Solve for the ff: a. length of the symmetrical curve b. stationing and elevation of PC c. A circular pipe culvert is to be laid out as part of road drainage requirements. If the elevation of the invert of the culvert is 90.25 m., determine the volume of earthworks needed to cover the culvert considering a 20% shrinkage factor for the backfill. The culvert has an inner radius of 0.4 m and thickness of 0.1 m. Consider 1 m width of the road section.
