CE 3110 Su2020 Road Design Project The objective of this assignment is to apply what you have learned to design a road connecting two existing roads. The attached map shows the tangents in bold) that you will use in your design. You will need to design one horizontal curve and a complete vertical alignment Design criteria for the entire alignment: Design speed is SO MPH, 2 lane undivided road (1 lane cach direction with 12' lanes. The road should have 6' shoulders. ROW is 60 Normal crown: X"/loot (2%) Max superelevation rate 6% Maximum grade: 10% Must design for stopping sight distance. Note: the road should be near level [+/- 2X) at the intersections with the existing two roads Required Plan and profile sheet(s) of the horizontal and vertical alignment. You should do a preliminary horizontal alignment design on the provided contour map and then transfer your design to the plan and profile sheet. A sample plan and profile sheet is attached. All drawings must be drawn to scale (make sure you specify the scale). Hand drawings are fine and AutoCAD is not required. HorizontalAlignment. For the horizontal alignment, the design should be stationed appropriately, and include curve details and super elevation information for the curve. Vertical Alignment. For the vertical alignment, your design should try to minimize earthwork. You should exaggerate the vertical scale. Be sure to include the grades and critical vertical curve info. One more note, you will need to interpolate elevations from the contour map to determine existing ground elevation before you start vertical alignment Other Make sure that you include any calculations that you made as well as the preliminary horizontal alignment design. Also, you must show that you have adequate sight distance through your vertical curves.
