BCN 3727 CONSTRUCTION SITEWORK & EQUIPMENT
Homework Assignment #2
1. In your project, you have decided to use dump trucks to excavate and haul the fill material.
The empty weight of a truck is 38 tons. The distance between the borrow and the construction
sites is 4 miles, and the road has an average uphill grade of 2.5% when travelling from the
borrow site to the construction site. When fully loaded, the truck can carry 20 tons of fill
material (LCY). You have investigated that the average tire penetration when the truck is

Road uphill grade=2.5%
Capacity of truck = 20 tons,
Penetration of tire = 1.5inch
Grade resist...
