Item Description
Trails Maintenance Rating System
Reviewed by
Justin Femrite, Public Works Director

Cal Portner, City Administrator
Action Requested
Discuss a rating system for the city’s trail system.
Recommend, by motion, a target system average rating for the overall trail pavements.
Background/Discussion
On November 4, 2020, the Commission reviewed a video of popular trail segments and discussed the need to
prioritize maintenance and replacement. Many indicated a desire to have funding for trails maintenance.
Engineering staff has mapped all segments and rated their pavement condition on a 0-10 index, much like the
Street Pavement Rating Index which uses a 0-100 index.

Supplement distress review with the Asphalt PASER Manual, produced by the University of Wisconsin-Madison Transportation Information Center.
New Construction. Fog seal within 2- years of
construction.
Severe surface raveling. Longitudinal and transverse cracks (open more than
1/2") with secondary cracks fully developed. Longitudinal cracks developed along
trail edge. Patches and trail edges in fair condition. Tree root or rodent
damaged (heaves or sunken) areas spaced between 50'-100'.
Severe surface loss with closely spaced longitudinal and transverse cracks that
have developed into second and third cracks. Patches and trail edges in fair to
poor condition. Tree root, rodent damage and other pothole areas spaced less
than 50'.
Severe surface loss with closely spaced longitudinal and transverse cracks that
have developed into full alligatoring. Patches and trail edges in poor condition.
Tree root, rodent damage and other pothole areas spaced less than 50'.
Severe distress with extensive loss of surface integrity
Failed. Redesign and reconstruction of trail
including aggregate base, areas of subgrade
correction and drainage improvements.
Nearly unusable. Redesign and reconstruction
of trail including aggregate base, areas of
subgrade correction and drainage
improvements.
Candidate for a Full Depth Reclamation (FDR)
with new pavement. Consider root treatment
as part of the reconditioning effort.
Very aged with structural edge degradation.
Recondition with patching of worst areas and
bituminous overlay of full section. Consider
root treatment in isolated areas.
None
None
No longitudinal cracks. Occasional transverse crack, widely spaced (40' or
greater). All cracks sealed or tight (open less than 1/4").
Very slight or no raveling, surface shows few signs of wear. Longitudinal and
transverse cracks (open 1/4") spaced 10' or more apart, little or slight crack
raveling. Few patches and trail edges in excellent condition. Tree root or rodent
damaged (heaves or sunken) areas spaced 500' or more.
Slight raveling (loss of fines), surface showing signs of wear or degradation.
Longitudinal and transverse cracks (open 1/4"- 1/2") spaced 10' or less apart with
some block cracking developing. Patches and trail edges in good condition. Tree
root or rodent damaged (heaves or sunken) areas spaced between 200'-500'.
Moderate raveling (loss of fines and course aggregate). Longitudinal and
transverse cracks (open more than 1/2") with secondary cracks now developing.
Signs of longitudinal cracking developing along trail edge. Patches and trail edges
in fair condition. Tree root or rodent damaged (heaves or sunken) areas spaced
between 100'-200'.
Surface aging and edge degradation.
Recondition most cracks and edge deformation
with velocity patching. Potential candidate
for a micro seal or bituminous overlay after
patching.
Shows signs of aging. Sound structural
condition. Cracks treated with a combination
of standard filling and velocity patching.
Surface condition should be extended with
micro seal.
Shows limited signs of aging. Maintain with
standard crack filling (routed and rubber filled).
First signs of aging. Recent fog or micro seal.
Little or no maintenance required.
Recent overlay, like new. Fog seal within 2-
years of last overlay.
