In a certain portion of ongoing construction of Clark Subic road, a parabolic curve is designed to connect a +6% grade and a -4% grade. The curve is to pass through point “P” the stationing of which was 35+280 and the elevation is 198m. If the grade intersection is at station 35+300 and the elevation is 205 m, determine the following: B. Length of the curve. C. Location of the summit from PT. D. Elevation of summit.

3. A grade descending at the rate of -4% intersects another grade ascending at the rate of +8% at station 2+000, elevation 100m. A vertical curve is to connect the two such that the curve will clear a boulder located at station 1+980, elevation 101.34. Determine the necessary length of the curve. Sketch the curve.
CONNECT A FORWARD TANGENT OF 3% AND A BACK TANGENT OF-15% BY A 300 M SYMMETRICAL PARABOLIC CURVE. IT WAS DISCOVERED THAT THE GRADE INTERSECTION AT STA 10+100 with ELEVATION 50 M FALLS ON ROCKY SECTION WITH THE EXPOSED BOULDER AT ELEVATION 102.67. TO AVOID ROCK EXCAVATION, IT WAS DECIDED TO ADJUST THE VERTICAL PARABOLIC CURVE THAT THE CURVE WILL JUST CLEAR THE ROCK WITHOUT ALTERING THE POSITION OF PC AND THE GRADE OF EACH TANGENTS. DETERMINE THE ELEVATION AND STA OF THE NEW PT.
