This chart describes the PASER rating system in detail and
provides a description of the all the rating levels from 1 to 10 and
what can be expected for each rating level. Note that
individual pavements will not have all of the types of distress
listed for any particular rating. They may have only one or
two types.
Surface
Rating |
Visible Distress |
General Condition / Treatment Measures |
| 10 |
Excellent |
None |
New construction |
| 9 |
Excellent |
None |
Recent overlay, like new. |
| 8 |
Very Good |
No longitudinal cracks except
reflection of paving joints. Occasional transverse cracks,
widely spaced (40' or greater). |
Recent sealcoat or new road mix.
Little or no maintenance required. |
| 7 |
Good |
Very slight or no raveling, surface
shows some traffic wear. Longitudinal cracks (open 1/4")
spaced due to reflection or paving joints.
Transverse cracks (open 1/4") spaced 10 feet or more apart,
little or slight crack raveling.
No patching or very few patches in excellent condition. |
First signs of aging.
Maintain with routine crack filling. |
| 6 |
Good |
Slight raveling (loss of lines) and
traffic wear. Longitudinal cracks (open 1/4" - 1/2") due to
reflection and paving joints.
Transverse cracking (open 1/4" - 1/2") some spaced less than
10 feet.
Slight to moderate flushing or polishing.
Occasional patching in good condition. |
Show signs of aging, sound
structural condition. Could extend life with sealcoat. |
| 5 |
Fair |
Moderate to severe raveling (loss
of lines and coarse aggregate). Longitudinal cracks (open
1/2") show some slight raveling and secondary cracks.
First signs of longitudinal cracks near wheel path or edge.
Transverse cracking and first signs of block cracking.
Slight crack raveling (open 1/2").
Extensive to severe flushing or polishing.
Some patching or edge wedging in good condition. |
Surface aging, sound structural
condition. Needs sealcoat or non-structural overlay. |
| 4 |
Fair |
Severe surface raveling. Multiple
longitudinal and transverse cracking with slight raveling.
Block cracking (over 25 - 50% of surface).
Patching in fair condition.
Slight rutting or distortions (1" deep or less). |
Significant aging and first signs
of need for strengthening. Would benefit from recycling or
overlay. |
| 3 |
Poor |
Closely spaced longitudinal and
transverse cracks often showing raveling and crack erosion.
Block cracking over 50% of surface.
Some alligator cracking (less than 25% of surface).
Patches in fair to poor condition.
Moderate rutting or distortion (1" or 2" deep).
Occasional potholes. |
Need patching and major overlay or
complete recycling. |
| 2 |
Very Poor |
Alligator cracking (over 25% of
surface). Severe distortions (over 2" deep).
Extensive patching in poor condition.
Potholes. |
Severe deterioration. Need
reconstruction with extensive base repair. |
| 1 |
Failed |
Severe distress with extensive loss
of surface integrity. |
Failed. Needs total
reconstruction. |
Note: Individual pavements will not have all of the types
of distress listed for any particular rating. They may have
only one or two types.
