Problem #2:

• You are a project engineer for a large road way project. The roadway to be constructed is 3 miles long and 60 feet wide.
• The following pavement design specifications have been issued:
  • Base coarse: 6 DGA

• Stabilized base: 4

• Bottom coarse of asphalt: 3

• Top coarse of asphalt: 2 Determine the following information:

1. How many tons ofeach material isrequired? Research andmake an assumption ofa unit weight for each material. Draw a cross-section of the specified pavement design.
2. Assuming 10 wide lanes, and that you cannot work on more than 50% of the roadway at a given time, how many pieces of the following equipment would you consider utilizing? Assemble a sketch depicting paving operations, including lanes opened/closed, and pieces of equipment utilized.
   • Material hauling trucks (assume truck can carry 20 tons/load)

• Bituminous distributors

• Asphalt paving machine (assume 10 wide)

• Vibratory rollers (assume 6 wide)

• Explain your rationale through illustrations as well as written description.
