Pavement Maintenance - Quiz

Quiz Question

1. For asphalt or tar-surfaced pavements (including asphalt overlay of concrete) a sample unit is defined as an area of approximately:
2500 square feet
3500 square feet
4500 square feet
2. For concrete pavements with joint spacing less than or equal to 30 feet, the sample unit is an area of 20 slabs (plus or minus 8 slabs)
True
False
3. For slabs with joint spacing more than 30 feet, imaginary joints should be assumed. These imaginary points should be less than 30 feet apart. This is done for the purpose of defining the sample unit.
True
False
4. Pavement condition is related to several factors, including structural integrity, structural capacity, roughness, skid resistance/hydroplaning potential, and rate of deterioration. Direct measurement of all these factors requires expensive equipment and highly trained personnel. However, these factors can be assessed by observing and measuring distress in the pavement.
True
False
5. The pavement condition rating is based on PCI. The PCI measures the pavement’s structural integrity and surface operational condition.
True
False
6. Figure 3-2 is a completed form of:
Concrete pavement inspection sheet
PCI rating of the concrete slabs
A system diagram of the pavement sections.
7. Figure 3-6 shows:
The 5 steps for calculating the PCI
Calculating the coefficient of friction on the blocks
Calculating the structural capacity for the concrete blocks
8. Figure 4-1 shows a completed form for :
Section evaluation summary
Section PCI measurement
Section maintenance & repair schedule
9. In table 4-1; the asphalt distress type, alligator cracking, corrugation, edge cracking, depression, and potholes are caused by:
Load
Climate
Moisture and drainage problem
Or other factors
10. In table 4-2; general classification of concrete distress types, the linear cracking, popouts, shrinkage cracks are caused by:
Load
Climate
Moisture and drainage problem
Or other factors
11. The flowchart in fig. 4-9 shows process for:
Calculating PCI
Identifying the distress type in the pavement
Process of determining maintenance and repair needs
12. Table 4-4 shows the asphalt concrete distress types and M& R (maintenance and repair) alternatives
True
False
