# Pavement Maintenance

## Quiz Questions

 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
