Tasks to be Completed
Task 1. Acquire a topographic map of a suitable area. Discuss possible terminal points with your instructor and define any areas that are environmentally sensitive or especially hazardous.
Task 2. Develop an optimum roadway alignment. Review AASHTO and/or local guidelines to check for grades, vertical curves, sight distances, or drainage requirements that are not met by the selected alignment. Modify as necessary.
Task 3. Prepare a vertical profile diagram of the ground and centerline for the selected route by following the rules listed below.
Task 4. At 100-ft stations, prepare cross-section diagrams of the ground and superimpose a highway cross-section template. Calculate cut and fill areas. Section lengths and average end areas may be used to calculate the cut and fill volumes.
Task 5. Complete the earthwork calculations using an appropriate shrinkage factor. Prepare a mass-haul diagram and determine whether you will have to borrow or waste any material in order to complete the project. Attempt to balance cut and fills.
