February 13, 2024 5 Year CIP Pavement Plan 222
• Background
• Pavement 101
• Pavement Management Principles
• Review Pavement Conditions and Needs
• Recommendations
Presentation Goals:
February 13, 2024 5 Year CIP Pavement Plan 3
• City voters passed 1/2 cent sales tax
Measure I (Streets & City Services) in
November 2016
• Adds $1M/year towards street
improvements
Background:
PAVEMENT 101
What Determines a Pavement Section?
Pavement Deterioration Cycle
Asphalt concrete deteriorates in two ways:
Pavement Deterioration
Oxidizing effects of sun and water Fatigue from heavy wheel loads 8 The Impact of Sun and Water
9 The Impact of Heavy Loads
10 Block
Cracking
Alligator
Cracking
Transverse or
Longitudinal
Cracking
Weathering or
Raveling
Common Pavement Distresses
11 • Alligator Cracking
• Block cracking
• Distortions
• Longitudinal / transverse cracking
• Patches / utility cuts
• Rutting / depressions
• Weathering / raveling
Evaluating Common Pavement Distresses
12 Evaluating Pavement: the PCI
100 – 91 = Excellent
90 – 71 = Good
70 – 51 = Fair/ At Risk
50 – 31 = Poor
30 – 0 = Failed
Developed by the U. S. Army Corp
of Engineers during World War II
and standardized by ASTM, the
PCI is an objective and rational
basis for determining pavement
condition and establishing
maintenance priorities.
PCI = 100
Excellent 100-91
PCI = 85
Good 90-71
PCI = 68
Fair 70-51
PCI = 60
Fair 70-51
PCI = 51
Fair 70-51
PCI = 38
Poor 50-31
PCI = 28
Failed 30-0
PCI = ?

36 RECOMMENDATIONS
• Continue to follow 5 Year Plan
• Presented to Council - February 27, 2024
• Projected PCI of 68 in FY 28/29
• Continue to seek funding to off-set increased prices
• Continue to evaluate Value Engineering
opportunities
• Continue to track progress
37 QUESTIONS
38 Crack Sealing Treatment
• The right treatment for
block or transverse
cracking.
• Inexpensive.
• Prevents water from
seeping
beneath the asphalt to the
subgrade where structural
damage occurs.
39 Slurry Seal Treatment
• The right treatment for
raveled pavement in traffic
areas with speed limits
above 15 mph.
• Skid resistant.
• Fills in minor cracks,
creates a uniform finish
and provides a weatherand water-tight surface.
40 Cape Seal
• The right treatment between
an overlay and a slurry seal.
• Combines a chip
(aggregate)
layer followed within a few
weeks
by a slurry seal for
durability.
• Prevents water damage to
the
road bed and provides a
new
wear surface.
• Significantly extends
pavement life when
combined with crack sealing
and surface patching.
41 • The right treatment for
severely
deteriorated pavement.
• Overlays existing pavement
with a new layer of
bituminous asphalt.
• Thickness depends on
existing
pavement condition and
traffic.
• Strengthens the overall
pavement structure and
improves ride.
Overlays
42 Reconstruction
When a pavement has failed or reached the end of its
service life, it requires complete removal and replacement of the existing pavement structure. Reconstruction may
use new or recycled paving materials or a combination of both.
• Grinds the existing asphalt
surface and mixes it with
the aggregate base.
• Strengthens the existing
base and forms a stronger
foundation for
reconstruction.
• Improves drainage.
• Eliminates bumps, humps
and rutting.
