1.
Black |
New
surface is smooth and crack free. |
After curing, deterioration starts. Much like a finish on a new car,
sealcoating provides a wearing surface that preserves the original
surface. |
|
2.
Dark Grey |
Oxidation is starting. Small shrinkage cracks appear and allow
surface water to penetrate below the surface. |
Sealcoating will fill small cracks and will halt oxidation.
Sealcoating provides a complete surface seal. |
|
3.
Grey |
Shrinkage cracks are getting longer and wider. Surface oxidation
pronounced. More surface water is penetrating to the base.
|
Sealcoating, along with crack repair, stops surface damage. The
surface will be sealed and original appearance is restored.
|
|
4. Light Grey |
Reaching critical
point where increasing moisture penetration is damaging base.
Surface lines are being abraded and surface is getting rough.
|
Adequate repair
and sealcoating will stop surface deterioration. Some larger cracks,
though sealcoated and reduced, might remain visible. Asphalt is
sealed to prevent further weather and oxidation damage. |
|
5. Light Grey to
White |
Oxidation,
cracking, abrading, and base damage occurring at increasing rate.
Surface stones are being dislodged by traffic. Surface texture is
open and rough. |
This is your last
chance for proper sealcoating! Further deterioration will inevitably
lead to an expensive overlay or complete replacement of asphalt.
|
|
6. Light Grey to
White |
General
disintegration rate accelerated due to previous base and surface
damage. Shrinkage at curb lines creating large gaps. |
If moisture damage
to base is not too great, sealcoating or an overlay may extend
surface life. It is no longer practical to sealcoat until after
extensive repairs are completed. |
|
7. Bone White |
Base failure has
allowed affected area to settle and crack in gator pattern. Base
failure hastened by previous water penetration. Base and surface
failure spreads from this point. Surface is disintegrating rapidly. |
Extensive infrared
repairs or an overlay is a must! Sealcoating will not stop
base collapse. |
|
8. White |
Areas are breaking
up. Loose blocks are rocking and can be dislodged. General surface
is very poor. |
An overlay or
complete replacement of asphalt is required. |
|
9. White |
Large pieces of
pavement are breaking off edges. Traffic is forced to slow down to
avoid large holes. |
An overlay or
complete replacement of asphalt is required. |
|
10. White
|
Base materials are
splashed out. Surface is heaved and generally broken. |
Replacement of
asphalt is required. |
