| When
asphalt has reached a point where it has lots of patches, cracks
and otherwise is showing its age, an overlay may be called for.
The existing pavement is repaired to a point where it will provide
a solid base for the overlay, and then two inches of hot-mix asphalt
are placed and compacted. In some instances a paving fabric is incorporated
with the overlay to separate the new asphalt from the old, cracked
asphalt. |
