Summary
RECOMMENDED ACTION: Discussion
BACKGROUND
Council last discussed the Pavement�Ianagement Program at the Work Session on September 9, 2014. At
that meeting, the pros and cons of different pre��entative maintenance activities were discussed. Council
also requested that staff pro�-ide historical information on�vhen road�vays �vere scheduled for an
unprovement compared to pa�-ement age.
At this time, staff�vould like to request Council feedback regarding two options for preventative
maintenance activities. Additionally, information is included regarding the age of road�vay s and the timing
for past public improvement projects.
PREVENTATIVE MAINTENANCE OPTIONS
"1'he city-is currendj- chip sealing all road�vay s �vith pa�-ement that are three�-ears old. This includes ne�v
roadways and those that were paYt of an overlay project thYee y�ears ago. �1 map is pYOCided showing the
roadways planned for preventative maintenance in 2015.
At the Work Session, concern was raised regarding the amount of excess rock following a chip seal
project. Rocks�veYe found in the gutter line and near pond outlets along many of the roadways that had
been chip sealed over the last few yeaYS. Since the Work Session, staff has in�-estigated this issue and
found that city� cYe�vs had historically increased the amount of stYeet s�veeping in neighborhoods �vith
recent chip seals fox one to t�vo ��ears after the project. It�vas determine that streets chip sealed in 2012
and 2013 �vere not s�vept as regularly�which like1�- led to more accumulation of rocks. �Ioving forward
monthly inspections of streets that have been chip sealed�vill be scheduled to determine�vhen additional
s`veeping is necessary.
The following are two different types of preventative maintenance activities discussed.
Chip Seal:
��sphalt emulsion and rock chips are applied to the road�va�� to protect the road�va�� surface from
environmental aging, moisture damage and oxidation.
• Pros:
o Protects the pavement from the deteriorating effects of sun and�vater
o Increases the surface friction on a road�vay�
o Traffic can be placed on the road once the chips are placed so there is no dela5�in�vaiting
for a chemical break or a cure time
o Provides a skid resistant surface and seals the surface
• Cons:
o There are concerns related to chip seal stripping
o Should not be used on roads�vith a large numbers of potholes or rutting
o Rough road surface is not al�vays ideal in recreational areas for rollerbladeYers
o Residents can track the rocks into their homes and make a mess
• Cost: �1.30 to �1.45 per square yard
Microsurfacing/Slurry Seal:
� mi.� of crushed aggregate, mineral filler, and lateY-modified, emulsified asphalt that is effective at sealing
lo�v-severity cracks,including fatigue cracks, longitudinal cracking, and transverse cracking.
Apple Valley has used this technique in the past as an alternative to chip sealing. Apple Valley has noted
that they�like the visual look of the product but that it is not necessarilyr more cost effective compared to
other methods. Recently, microsurfacing�vas completed on Dodd Bouleaard from Diamond Path to Pilot
Knob.
• Pros:
o No loose rock
o Seals aged and ra�-eled pavement
o Corrects wheel rutting (up to 1.5")
o Corrects minor cracks
o I�Zaintains ride quality
o Black surface
• Cons:
o Expensive
o Prone to reflecti�-e cracking
o Rough surface that pedestrians ma�- not like
• Cost: �3.50 per square��ard
Options for Consideration:
1. Continue chip sealing progYam in 2015 with increased stYeet sweeping
r,pproximate cost: $175,000
2. Microsurfacing on Brazil tivenue as a test road�va��
Chip seal on all remaining road�vays in 2015
�-�pproYimate cost: �225,000
Pre�entative maintenance projects are funded through the Cit��'s Street Capital Improvement Fund (CIP).
r�ny increase in expense greater than �175,000 is not planned for in this budget and additional funding�vill
be needed.

TIMING OF PAST PAVEMENT MANAGEMENT PROJECTS
Council requested additional information regarding the agc of roadways included with pavement
management pYOjects. A table has been provided that lists the roadways that were included with each
project from 2009 to 2014.
The table also lists the t�-pe of project completed, eYpected life based on the tt�e of project, and the age of
the road�vay. In most cases, the pavement age was eer�� close to the estunated lifecycle graph that the
pa�-ement management sy�stem is based on. It should be noted that each road�va�-listed�vas constructed
�vith different pa�-ement and subgrade materials and the5� have all be subjected to different traffic loadings.
Specificall��, the 2011 Street Improvement Project falls �vithin the age range of a mill and o�-erlay�project.
Due to subgrade issues, the Cin-mo�ed forward with a rehabilitation project. This project included
replacing the pavement and subgrade corrections.
CONCLUSION
Staff is Yequesting feedback on the preventative maintenance options.
