Problem• Deteriorating Pavements

– More traffic, trucks, buses– Less funding available– Road materials are more

costly– Useful life of materials

seems shorter

Answer

• Do nothing (doesn't work)

• Repeat last years approach (again & again)

• What is the industry doing?

Why Micro PAVER?

• Developed by the Army Corps in the late 70’s•Recommended by APWA (American Public Works Association) •Optimizes funds allocated for M&R• Utilizes the PCI methodology• PCI became an ASTM standard in 1999• Most widely used system in the world.

Pavement Management

• Plans, Organizes & Documents

• Helps make better decisions

• Provides support data for decisions

• Answers what if scenarios

• Objectively answers “what can be left out”

• Shows the progress or lack of

• Objective recommendations

What is a Pavement Management System? (Micro PAVER)

• Inventory

• Inspection (ASTM)

• Reporting

• Modeling

• Condition Analysis

• M&R Planning

Inventory

• Street Name (block - to & from)• Length, width, area• Type of pavement (asphalt, concrete, etc.)• Rank (arterial, collector, residential, bus

route)• Last const. date• Zones• Other Items

Sections

Numbered: West to East & South to North

Inspections

• ASTM (American Society for Testing and Materials)

• Objective• Distresses• Severity• Quantity• Feet on the ground• Data must be correct Training & Dedication is

essential • Micro PAVER produces a PCI (Pavement Condition

Index) 0 to 100

Inspection Procedure (Alligator cracking)

Reporting, Analyzing, Planning

• Graphs, Bar charts, Maps– Where you are now– Where you can be– Where you will be

• How to get there– Funding– Value of Preventive Maintenance

$ Savings

• Utilizing a Pavement Management System will save a minimum of 10 %.

$1.00 for preventive maintenance here . . .

$5 to $7 for Severe Maintenance Repair here… or several years of pothole patching if money is short !

Micro PAVER Provides

• A Plan that can be explained

• Documentation to support the Plan

• Reinspection to confirm the Plan is on track and working

• Objective before and after comparisons (responsibility)

• A format to test new ideas

Micro PAVER vs Dump Truck (or resurfaced street)

• The Micro PAVER is an investment in a new way of solving problems.

• It provides the documentation to direct and justify decisions to provide savings.

• This is an investment into having a better street system.

• The dump truck or resurfacing is gone in several years with minimal lasting benefit for the system.

When Funding is short

• The Best decisions need to be made • Best treatment - best street - best time• More Documentation is needed for

reasonable explanations– More public inquires are a certainty

• Illustrations of just what is the result will provide sooner refunding

• Be Proactive (something can be done)

Micro PAVER can produce

• A listing of Streets to be Treated in the next 3 – 5 years.

• Understanding that there are variables that could modify the list (up or down).– Funding, severe weather, material costs, changing

traffic patterns

• The list will include:– Preventive maintenance, routine maintenance and

severely deteriorated street repairs (good, fair & bad) “A Balanced Program”
