1. PASER Ratings for TwinCATS Planning Area
Presented at the
December TwinCATS Committee Meeting

2. A Brief Overview of How Roads are Rated
Pavement A Surface Evaluation and Rating

3. 10 & 9: Excellent No Maintenance required
10 is new construction or reconstruction less than a year old
9 is like new or any paving short of a full reconstruction

4. 8: Very Good
No longitudinal cracks except reflection of paving joints.
Occasional transverse cracks, widely spaced (40’ or greater).

5. 7: Good Very slight or no raveling, surface shows some traffic wear.
Longitudinal cracks (open ¼”) due to reflection or paving joints.
Transverse cracks (open ¼”) spaced 10 feet or more apart, little or slight crack raveling.
No patching or very few patches in excellent condition.

6. 6: Good Slight raveling (loss of lines) and traffic wear.
Longitudinal cracks (open ¼” – ½”) due to reflection and paving joints.
Transverse cracking (open ¼” to ½”) some spaced less than 10 feet.
First sign of block cracking Slight to moderate flushing or polishing.
Occasional patching in good condition.

7. 5: Fair
Moderate to severe ravelling (loss of fine and coarse aggregate).
Longitudinal and transverse cracks (open ½”) show first signs of slight raveling and secondary cracks. First signs of longitudinal cracks near pavement edge.
Block cracking up to 50% of surface.
Extensive to severe flushing or polishing.
Some patching or edge wedging in good condition.

8. 4: Fair Severe surface raveling.
Multiple longitudinal and transverse cracking with slight raveling.
Longitudinal cracking in wheel path.
Block cracking (over 50% of surface).
Patching in fair condition.
Slight rutting or distortions (½” deep or less).

9. 3: Poor
Closely spaced longitudinal and transverse cracks often showing raveling and crack erosion.
Severe block cracking.
Some alligator cracking (less than 25 % of surface).
Patches in fair to poor condition. Moderate rutting or distortion (1” or 2” deep).
Occasional potholes.

10. 2: Very Poor Alligator cracking (over 25 % of surface).
Severe distortions (over 2” deep).
Extensive patching in poor condition.
Potholes.

11. 1: Failed Severe distress with extensive loss of surface integrity

13. Treatment Options with Costs

16. Ratings By Year Vast majority of TwinCATS is rated in even years
Lake Township & Bridgman are rated in odd Years
Changes in the federal Aid network from year to year affect which roads are rated. For example the section in Lake Township rated in 2016 was not rated in previous years.
