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.
Occasional transverse cracks, widely spaced (40' or greater).
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.
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.
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").
