A cylindrical soil sample, 7.3 cm in diameter and 16.8 cm in height, is tested in a constant-head permeability apparatus. A constant head of 75 cm is maintained during the test. After 1 minute of testing, a total of 945.7 gm of water was collected. The temperature was 20 oC. The void ratio of the soil was 0.43. Calculate the following:

1. The hydraulic gradient

2. The flow rate

3. The discharge velocity

4. The seepage force per unit volume

5. The coefficient of permeability

Describe what happens, on the atomic scale, to cause differences in recovery in materials stressed within the elastic region and in materials stressed to an amount exceeding their yield strength

Grade Line Selection Factors in selecting the orientation of grade lines (vertical alignment):  Balance cuts and fills (economy)  Minimize rock excavation (economy)  Providing adequate drainage (safety  Aesthetics (appearance)  Compatibility with horizontal alignment  Design speed  Composition of traffic  Adequate visibility (safety)  and other factors .   list of factors in selecting the orientation of grade lines (vertical alignment) given, give an example in the field of one of these factors. You can create an example or write about a person experience. - give details.

Consider a T-shaped signalized intersection with the following geometric conditions and arrival vehicular flows in pcu/h as shown below. Assume the following:

▪ Left turn from the exclusive left-turn lane of northbound traffic (Lane NB1) is protected.

▪ Left turn from the shared left-turn and through lane of westbound traffic (Lane WB 1) is protected.

▪ The saturation flow rate for the exclusive left turn lane is 1785 pcu/hour. The saturation flow rates for all other lanes are 1700 pcu/hour.

▪ Amber of 3 sec. and all red of 2 sec. follow each through/right-turn green interval.

▪ Amber of 3 sec. follows the protected left-turn green interval.

▪ The pedestrian walk speed is 1.0 m/s and the pedestrian clearance time is 5 s.

Determine the designed signal timing. Present the duration of green and intergreen intervals for all phases in a tabular form

Identify which of the following items we need to know in order to establish a clear zone value:
          Design Year Traffic (ADT)
          Design Speed
          If the section of road is curved or not curved and the radius size if curved.
          Ground conditions outside of our EOTW ( such as shoulders and ditch slopes)

1. Using Engineering News Record (ENR), graph the construction cost index (CCI) (y-axis) vs. time from 2001-2011. 4 points per year - equally spaced. ENR is a weekly magazine. You will find the CCI in a section called Construction Economics and in the older issues a section called Market Trends. (Neatness Counts!)
