BASE PAVEMENT CORRECTION TABLE
| ||
---|---|---|
Average Coring Thickness
|
Corrective Action
| |
1 3/4 inch to 2 1/2 inch (up to 3/4 inch deficient)
|
Calculated tonnage of pavement deficiency will be doubled and
added to the specified overlay.
| |
1 3/4 inches or less
|
Additional "2 inch" lift of base pavement will be the standard
corrective action. However, the Public Works Director may require
additional corings (the number will be determined by the Director
of Public Works) which will be evaluated, by a MDOT certified lab,
for gradation, % bitumen, and compaction at the applicant's expense.
After an analysis of results, the Town may require the initial base
pavement to be removed and a new base pavement placed in accordance
with appropriate specifications.
