CEGR 2103 Surveying and Technical Drawing Class Exercise on Horizontal Curves, Verticals Curves and Earthworks In this exercise, we will be designing a new roadway extension from the north end of Robert Snyder Road back to N. Tryon Street. This assignment is divided into three parts. First, we will design the horizontal curves, then the vertical curves and finally, you will do earthwork calculations. The in-class assignment is due by the end of the day on April 26th and it is a group submission (no more than 4 per group) on Canvas. Horizontal Alignment Tasks 1. Roadway centerline needs to be stationed from beginning to end. 2. Calculate the PC, PT, T and L for both curves and you will need to re-station the P12 location. a. Curve 1 has a radius of 250 ft b. Curve 2 has a radius of 200 ft 3. Determine the new end station with the curves in place 4. On the plan-view sheet, label the PC, PT locations and draw in the horizontal curves. Vertical Alignment Tasks 1. Put in one vertical curve with a minimum K value of 50. 2. On the vertical profile sheet, draw in the existing ground along the centerline and the proposed new vertical curve. 3. Label the following on the new roadway on the profile sheet. a. PVC, PVI, PVT b. Percent grades of tangent sections c. K value d. Length of vertical curve Earthwork Tasks 1. Draw cross sections at every 100 foot stations (assume cut/fill volume at beginning station and ending station will be 0). You can draw this either by hand or use the CAD file to draw them and then calculate the area of each. 2. Calculate the cross-sectional area for each cross section and then determine the volume between cross sections and the total volume of cut and fill. Use the following table for the summary of your earthwork data.
Station Cut Area Fill Area (sq. Cut Volume IL) (eu.yd.) Pill Volume (cu.yd.) Cumulative cut-fill (cu.yd.) 0100 TH100 2100 3400 4100 5100 O100 7800 Ind Station Totals Calculations Include hand calculations for all of the horizontal and vertical curves as well as for the earthwork volume calculations using the average and method.
