Question

# Problem #1:You are a construction engineer working on a large concrete foundation project,

involving the placement of over 500,000 c.y of concrete. The construction site is adjacent to a salt-water source (bay) & it is decided to set up a concrete batch plant on site. The project schedule shows that the various concrete pours are to take place from April to September.

• What considerations would you make with regards to cement type, aggregate, water quality, and admixtures? Explain your considerations in detail.
• 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 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.
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?
• 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.
