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:
a. How many tons of each material is required? Research and make an assumption of a unit weight for each material. Draw a cross-section of the specified pavement design.
b. 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? - 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.
