PASER Surface rating Scale
10 Excellent
9 Excellent
New construction
Recent overlay, like new.
8 Very Good
No longitudinal cracks except reflection of paving
joints. Occasional transverse cracks widely spaced
40’ greater.
Recent sealcoat or new cold
mix. Little or no maintenance
required.
good
no ravelling Longitudinal cracks open ¼” due to
reflection or paving joints. Transverse cracks open
¼” spaced 10” or more apart,
First signs of aging. Maintain
with routine crack filling.
Slight ravelling loss of fines and traffic wear.
Longitudinal cracks open ¼” spaced 10’ or more
apart, little or slight crack ravelling. Slight to
moderate flushing or polishing. Occasional patching in good condition.
Could
extend life with sealcoat.
5 Fair
. Longitudinal and transverse crack open
½” show signs of slight ravelling and secondary
cracks. First signs of longitudinal cracks near
pavement edge. Transverse cracking and first signs
of block crackling. Slight crack ravelling open ½’.
Some patching or edge wedging in good condition.transverse crackling with slight ravelling. Block
cracking over 25-50% of surface. Patching in fair
condition. Slight rutting or distortions 1” deep or
less.
signs of need for strengthening.
Would benefit from a structural
overlay 2” or more.
3 Poor
Closely spaced longitudinal and transverse cracks
often showing ravelling 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.
Needs patching and repair prior
to major overlays. Milling and
removal of deterioration
extends the life of overlay.5
Alligator cracking over 25% of surface. Severe
distortions over 2” deep. Extensive patching in poor
condition. Potholes.
1 Failed
Severe distress with extensive loss of surface
integrity.
Severe deterioration. Needs
reconstruction with extensive
base repairs. Pulverization of
old pavement is effective.
Failed. Needs total
reconstruction
