IPAG GuidancePaul Hardy

Directorexp | consulting

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: GuidanceSuite of Guidance Documents available to download from

https://lgmaext.laservices.ie/transportation/IPAG/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 1Asset 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 2Network Referencing Recommends how roads should be

referenced to enable data to be stored against the network1. Linear referencing 2. Cross sectional positioning

Covers both rural and urban context

IPAG Guidance: Section 3Inventory & Data Management recommends the inventory data that

authorities should hold and provides guidance on data management

IPAG Guidance: Section 4Routine 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 & RatingComprises 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 # created by others in parallel with this project but

coordinate to support the overall aims of IPAG

IPAG Guidance: Section 5: Part 2Footway Condition Rating provides data that can be used to:

− Prioritise & programme footway renewals/resurfacing schemes

− Record and report condition (locally and nationally)

Condition Level

4 Good

3 Safe but Poor Appearance

2 Minor (functional) Deterioration

1 Major (structural) Deterioration

IPAG Guidance: Section 5: Part 2Footway Condition Rating Photos illustrate linked to potential

treatment

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

IPAG Guidance: Section 5: Part 3Drainage Condition Rating

Drainage Condition Rating System

Rated Condition of Drainage#

Action Road Condition Rating

Drainage Rating

Description

Poor Treat drainage

when treating road 1-6 Red

Drainage needs improvement as does the condition of the road. Drainage should be addressed prior to or in conjunction with the road scheme.

Fair

Drainage Improvement

Amber**

Drainage needs improvement but has not yet affected the road condition.

Maintain Existing Drainage (e.g.

clean out) Blue**

Existing drainage needs maintenance.

Good

Routine Maintenance.

Green

Continuance of routine cleaning etc. required.

IPAG Guidance: Section 5: Part 3Drainage 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 6Cost 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
