IPAG
Joint committee :develop a pavement
management approach for Irish Local
Authorities
 Reps from DTTS, LGMA and Local Authorities
(urban and rural)
 Guidance about to be publised
 Today: overview, let you know what exists,
and what next

IPAG: Guidance
Suite of Guidance Documents available to
download from


AG/default.aspx
Guidance is a start; will need training
 Will evolve and improve with use
 First cut at:
Setting Standards for the Future

IPAG Guidance: Section 1
Asset Register
Provides guidance on how to structure an
asset register
 Recommends recording by






Asset e.g. Roadway
Type e.g. National Primary Roads
Asset e.g. Road Name/Number
Component e.g. Road Segment/XSP
Also includes associated assets, structures,
drainage etc…
IPAG Guidance: Section 2
Network Referencing
Recommends how roads should be
referenced to enable data to be stored
against the network

Routine Maintenance Management

recommends the use of a systems based
approach to the management of routine
maintenance. Based on:






identification,
categorisation,
prioritisation,
repair and
reporting of pavement defects.
recommends the records that should be kept
to support pavement management.
IPAG Guidance: Section 5:
Condition Surveying & Rating
Comprises of:
 Part 1a: Rural Flexible Roads Manual#
(Pavement Surface Condition Index)
 1b. Urban Flexible Roads Manual#
(Pavement Surface Condition Index)
 1c. Concrete Roads Manual#
(Pavement Surface Condition Index)
 Part 2: Footway Condition Rating
 Part 3: Drainage Condition Rating

to
1 Major Deterioration
The footway has major
deterioration.
Major cracking, fretting,
potholing or scaling;
trip hazards exceeding
13mm, poor shape, severe
local settlement/subsidence
creating a difference in level
greater than 30mm.
 Check –Warrants treatment to strengthen and repair
e.g. removal of surface and loose material, patch and level base and
lay new wearing course

condition of the road.
Drainage

be
addressed prior to or in
conjunction with the road
scheme.
Drainage

yet affected the road
condition.

maintenance.
needs
Continuance of routine
cleaning etc. required.
IPAG Guidance: Section 5: Part 3
Drainage Condition Rating
Poor Condition
Road pavement structure has been affected*, and
-
observed or known presence of fast flowing water on the pavement (that has caused damage),
or observed or known presence of extensive ponding, flooding or standing water
-
substandard road profile (cross section or longitudinal profile)
(* Road pavement condition rating of 1-6 )
Poor Condition Significant repairs, remedial works or improvement works required.
IPAG Guidance: Section 6:
Pavement Management Strategies

recommends how pavement management
strategies should be developed including
how to use asset data to aid




Identification of potential sites
Analysis of the options for treatment
Creation of short term programme of schemes
Creation of long term projection of funding
needs.
IPAG Guidance: Section 6:
Pavement Management Strategies
Step 1. Condition Surveys (Network Level)
Step 2. Investment Need &
Categorisation (Network Level)
Step 3. Prioritisation (Network Level)
Step 4. Site Inspection (Project Level)
Step 5. Programme (Project Level)
Based upon 5
broad
recommended
steps
IPAG Guidance : Section 6
Cost Projection Spreadsheet
• Crude initial
methods of showing
potential effect of
different budget on
condition
• A pilot , which will
need testing as
better condition data
becomes available
• Potentially powerfull
tool …
• EVENTUALLY
IPAG Guidance: Section 7:
Reinstatements

recommends records should be kept of
utility company reinstatement. It refers
specifically to those records required to
assist with pavement management.



Regime of inspections
Specific records to be kept
Long term damages (enable from before and
after costs.. Eventually)
IPAG Guidance: Section 8:
New Roads and Taking in Charge
Recommends methods to ensure that roads
constructed by developers or contractors
meet standards for ‘taking in charge’.
 Guidance on inspections and checks to
confirm construction depths and materials
specifications are met
 Most critically states what records and data
developers should be required to hand over
prior to ‘taking in charge’

What Next

What:



IPAG : Promote the existence and purpose of
the guidance
Authorities; Adoption and use
Collectively; Refinement and improvement
How:



Communication will be the key to obtaining
benefit from this work
IPAG: provide clear and easy to access training
Authorities: constructive feedback on
experience of adopting it
