Determine the PCI index of a local street assuming the following:

1. Asphalt pavement
2. The street block is one mile long and 26 ft wide
3. The # of units to be tested is based on a curve that represents a standard deviation of 10
4. Assume size of each unit is 3000 sf (may be varied based ASTM D6433)
5. For the purpose of this exercise, perform your analysis on only half the units that you determined need to be inspected
6. 40 ~ 1x5 ft Alligator cracks were observed. They are equal in severity proportion (ex if 3 cracks are classified as low, then 3 are medium & 3 are high) evenly distributed
7. Transverse cracks were detected full width of the road every 500 ft. 1 longitudinal crack detected full length of the block
8. 10 Potholes were detected & were evenly spaced
9. 4 ~ 1x10 ft rutting were observed at the each end of the street block

Criteria:

• Draw a layout of the roadway
• Draw/show the distresses noted above
• Show your no. of units
• Show the units to be tested
• Show the ones you performed the analysis on as noted in item 5 above
• Provide the analysis
• Determine the PCI
• Provide your conclusion

Hint: Use the forms, charts/ASTM D 6433
