Highway Drainage

Highway drainage is the process of extracting and regulating the excess surface water on the pavement by giving the desired slope. The construction of a highway drain helps to divert the water present on the surface, and sub-grade by the means of slope. Highway drainage systems are a necessary part of smooth functioning of traffic, since the highway drainage systems provide proper disposal of unwanted substances from the highways.

2. The influent to a wastewater treatment plant has an influent soluble BOD concentration of 200 mg/ and a particulate BOD concentration of 100mg/I, how large must the aerated basin (activated siudge basin) be assuming a total BOD loading rate of 0.6 kg BOD/m2-d. Assume that the primary sedimentation basin removes 40% of the particulate BOD and 0% of the soluble BOD. The flow is 1 m/s.

After the heavy rain brought by Irene passed over Vermont, the Winnooski River has raised to over 5 feet above its flood elevation. The flood crest is expected to arrive to Montpelier, state capital, in 48 hours. You are an engineer in charge ofcalculating the flood defense by increasing the levee top elevation. Your estimate calls for 5000 CY of compacted material needed before the flood crest arrives. You have two borrow pit options: borrow pit A is located 1 hour away and has 7 Caterpillar 69C trucks with 30.9 CY capacity available. Borrow pit B is located 30 minutes away but has only 3 Caterpillar trucks with the same capacity. Assuming arround the clock work in the next 48 hours calculate which option will allow for completion of the work within the time constraint given. Records on file show the following soil properties at locations A and B: A: Y= 120 pcf, w = 18% B: Y= 125 pcf, w = 12% In order to assure adequate stability of the levee slopes, it will be required to compact…
