Typical Asphalt Pavement Section
• Aggregate Base Course is a very important element of any pavement section.
• It is typically composed of crushed rock about ¾” in size down to dust.
• When properly compacted, it provides the foundation upon which asphalt or concrete 
is placed on.

Pavement Management Process

• Develop and organize the pavement inventory.
• Assess the current condition of pavements.
• Develop models to predict future conditions.
• Report on past and future pavement performance.
• Develop scenarios for pavement management based on 
the budget or condition requirements.
• Plan and prioritize projects.
• Suggest most cost-effective treatments for the projects.

• Two downward mounted 
lasers
– 3D, high-speed scanning and 
pattern recognition
– Collect additional 
International Roughness 
Index (IRI)
– Also, collects pavement 
distress and deformation to 
full depth of the roadway
11
Data Collection and Validation

• High-definition 4k 
cameras
– Collect forward, 
downward, and rearward 
pavement 
distress/deformation
• Realtime validation of 
collected data by the 
technician in the field
– Distress severities and 
extents

• Recent 7 years – Stabilized pavement throughout 
the City.
• Next 10 years – Bring pavement up to good 
condition (70-82 PCI), so that we spend less and 
thereby maximize spending to provide longer 
pavement life.
• Ultimate target – Bring pavement to excellent 
(82+ PCI) condition.
18
PMP Strategy

19
Analysis and Project Planning

• Based on current funding levels (PMP budget + Bonds) 
~30M/Yr.
• Identify annual budget to:
– Maintain current PCI.
– Funding for PCI of 72 in 5 years & 10 years.
– Funding for PCI of 82 in 5 years & 10 years.
