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. |

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. |
