INDUSTRY PERSPECTIVE AND ACTIVITIES TO HELP IMPLEMENT MAP-21
ASSET MANAGEMENT REQUIREMENTS
September 2017
-
- 2 -
MAP-21 TRANSPORTATION LEGISLATIONGoal is to have a Long-term,
Strategically-driven Performance Based Management Program that uses
Targets,
Measures and Investment Strategies to improve project
decision-making
Performance Based Management Program
Asset Management Plan should link the Goals, Condition,
Measures, Targets, and Planning
National Goals (MAP 21 – §150(b))Maintain Highway assets in
a state of good repair.
Performance Measures (§150(c))Pavement Condition
IRI, Cracking, Faulting, etc.
Performance Targets (§150(d))What are acceptable condition
measures
Pavement Condition (§150(c))Asset condition and how
is it changing
State Performance Management (§119(e))
Risk-based Asset ManagementPerformance Driven
Statewide Planning (§135(d))Performance-based Approach
-

OVERALL, INDUSTRY HAS HIGH PRAISE OF THE MAP 21’S PERFORMANCE
MEASURES AND ASSET MANAGEMENT RULE MAKING
We commend FHWA on how they balanced the goals and intent of MAP
21 legislation and the State DOTs ability to implement AMPs for our
National Highway System
We believe that many of the recommendations follow or build on
best practices and will help improve will improve how state DOTs
manage their highways and bridges
We support FHWA’s efforts to promote transparency
We continue to support State DOTs by providing quality resources
to assist in constructing, rehabilitating, reconstructing, and
repairing our nation’s roads and bridges
While Asset Management and the rulemaking provide great
potential for DOTs, we believe that there are some shortcomings and
missed opportunities

ASSET / PAVEMENT MANAGEMENT PLAN IS INTENDED TO DEFINE THE PATH
FOR AN AGENCY TO MEET ITS LONG TERM GOALS
1. What is the current state of my assets?
2. What is my required level of service/ performance?
3. Which assets are critical to sustained performance?
4. What are my best “Operations and Maintenance” and “Capital
Improvement” investment strategies?
5. What is my best long-term funding strategy?
Questions to be answered
Issue 2: A 10-year AMP requirement is not long enough evaluate
the economic impacts of different Investment strategies and
treatment options (promotes “band aid approaches”)

ASSET / PAVEMENT MANAGEMENT FOCUS IS ON DEVELOPING A “LIFE CYCLE
PLAN (LCP)” FOR NETWORK ANALYSIS

Management Plan”International Airfield & Highway Pavements
Conference, June 10, 2015
Illinois Tollway “Hymnal” Pavement Management Plan for JPCP –
with Preservation
Issue 3: Analysis stops at the network level and does not
evaluate alternate actions at the project level

CEMENT / CONCRETE INDUSTRY IDEAS FOR A WELL-WORKING ASSET
MANAGEMENT FRAMEWORK
Asset Management needs to:
Use a forward looking performance indicator that helps agencies
properly plan for the long term
Link the Network Level Analysis (Life Cycle Planning) and the
Project Level Analysis (Life Cycle Cost Analysis) to take into
account how different activity’s impact network performance
• Network analysis – allocates funds among classes of activities
(construction, maintenance, preservation, repair, rehabilitation,
and replacement actions)
• Project level analysis – tells what investment option for a
given project provides the greatest return (lowest life cycle
costs).
Include all the cement / concrete based options• Asset
management is not “code” for preservation activities only – there
will sections at different
condition levels− Need “mix of fixes”
• Most agencies have a limited number concrete options in their
planning program (if any at all)

All three are linked and intertwined with each other

Definition
• RSI tells HOW WELL and HOW LONG the pavement will serve the
public• A RSI=10 means that it is 10 years to next construction
treatment for that segment• A RSI=0 means that its condition is
worse than the agency’s defined trigger value
“Treatment” can be anything from preservation activities (i.e.
crack sealing) to full reconstruction for the segment
What it does
• Two pavement sections at the same condition are not
necessarily equal • They will require different management
strategies• RSI takes into account “rate of
deterioration”• Higher RSI pavements / networks deliver
higher value than lower RSI networks

OPPORTUNITY 1 – ADOPT A FORWARD LOOKING INDICATOR TO DISTINGUISH
HOW DIFFERENT PAVEMENT SEGMENTS ARE PERFORMING
Remaining Service Interval (RSI) is one possible forward looking
time element

RSI IS DETERMINED USING A MULTI-CONDITION APPROACH Uses Current
Condition & Predicted Performance Data
RSI builds on each DOT’s “condition” measures already being
required
• For each roadway segment, DOT determines “Time to Next
Treatment” for each distress
– Time to next treat. (IRI) = 16 years– Time to next treat.
(cracking) = 12 years– Time to next treat. (faulting) = 10
years
• RSI determination can be based on any distress or performance
indicator
Distress targets are set by each DOT• Performance predictions
are based on
modeling (Pavement-ME models, LTPPModels, FHWA PHT, state AM
models, straight line predictions, etc.)

AN EFFECTIVE MANAGEMENT PROGRAM REQUIRES A “MIX OF
FIXES”Agencies need to design their state’s program of projects and
pavement
treatments to meet minimum performance requirements
A Network’s RSI plot defines the minimum performance
requirements for the state’s program of projects
Treatment strategies are based on falling into “times frames”
that do not have a high percentage of pavements needing repair

• Performance Period gives typical range for the activity until
next treatment. Actual performance will vary based the specific
parameters used for each activity and project. For example, a
8-inch overlay will provide longer service than a 5-inch overlay.

investment categories
Construction – 5%(30+ years)
Maintenance – 20%(4-8 years)
Preservation – 5%(8-15 years)
Minor Rehab – 30%(12-20 years)
Major Rehab– 25%(15-30+ years)
Replacement – 15%(30+ years)

LCCA determines which treatment – that meets or exceeds the
performance requirements – is the lowest
cost alternate
Select Preferred Alternative
PAVEMENT / ASSET MANAGEMENT SHOULD BE A 2-STEP PROCESSSimilar to
a financial portfolio management process
Step 1 – Allocation of Funds at the network level based on “Time
to Next Treatment”
Step 2 – Selection of Activities that meet “Time to Next

ACTIVITIES THE CEMENT / CONCRETE PAVEMENT INDUSTRY IS DOING TO
HELP AGENCIES IMPLEMENT ASSET MANAGEMENT
Improve understanding how “allocation practices” and “strategy
selection approaches” impact a DOT’sperformance targets and cost
expenditures
Improvements to the “Allocation process” • Looks across long
time frames to account for long duration of pavement assets• Looks
at multiple pavement solutions and treatment options• Account
variability / uncertainty in both Performance AND Costs•
Computationally efficient process
Industry needs to step up and “own” Concrete Pavement
Performance• Asset Management is a “data driven” process. • We want
to work with DOTs to develop / provide performance data and
prediction curves for each
cement / concrete based options• At a minimum covers MAP-21
Performance Measurement distresses (cracking, faulting, IRI)
• Must fit into an agency’s AM / PM systems
