2. Overview Drivers for the Specification Review
Consultation process with stakeholders in TMR and industry (AAPA and CCAA)
Specification Suite Restructure

3. Bituminous Product Specification Changes
Drivers for the specification review were:
Requirements coming out of independent and Main Roads enquires and reports
Identified need for modification and standardisation (such as rationalisation of aggregate testing and properties across all specifications)
Better information about preferred material and construction practices
Performance issues with various products
Skid resistance requirements
Texture depths, PAFV
Availability of materials
CCAA and quarry registration systems
PMB’s tested at point of use
Limited industry data
Some negative outcomes for QTMR
Spray seal design requirments

4. Bituminous Product Specification Changes
MRS11.11 Sprayed Bituminous Surfacing (Excluding Emulsion)
MRS11.17 Bitumen
MRS11.18 Polymer Modified Binder
MRS11.19 Cutter and Flux Oils
MRS11.20 Cutback Bitumen
MRS11.21 Bituminous Emulsion
MRS11.22 Supply of Cover Aggregate
MRS11.30 Dense Graded Asphalt Pavements
MRS11.31 Heavy Duty Asphalt (new)
MRS11.34 Open Graded Asphalt Surfacing 4

5. Bituminous Product Specification Changes
Consultation with stakeholders:
Draft specifications released to stakeholders in December 2007
Initial response to proposals received in Feb 2008
Working groups were formed to discuss and resolve technical issues:
Pavements &Materials Branch
TMR Districts and Regions
AAPA and CCAA
Alliance Specification Task Groups
Binders | Aggregates | Sprayed Seals
Dense & Open Graded Asphalt | Heavy Duty Asphalt 5

6. Bituminous Product Specification Changes
Extensive consultation with stakeholders:
Over 30 participants involved specification review process
Most issues were resolved by the alliance working groups
Open and honest communication between participants throughout the formally documented process
Agreement has now been reached on most issues 6

7. Specification Task Groups
Binders
Russell Spies, Barry Rule, Sharon Forbes, Ron Carroll, Bevan Painter
Sprayed seals
Narelle Dobson, Peter Jamandijevic, Gavin Soward, Jason Jones, Peter Carbone, Les Millar, Rob Pollock, Graham Jones, Derek Martin
Input from the regions on all specifications 7

8. Specification Suite Restructure
New specification format
MRSXX
MRTSXX
Annexure
MRTS will replace PSTS
MRS Series: For traditional- construction only contracts
TS & PSTS Series: For other contract types (D&C, Alliance, and so on)
Difficulties arose with have two specification / technical standard sets:
Technical expert human resourcing
Errors and inconsistencies
Impost on suppliers and contractors 8

9. Specification Suite Restructure
MRS Series – Traditional contracts
Prescribes various material and construction requirements
Role of Superintendent included throughout documents
Annexures were included for local conditions and requirements
TS & PSTS Series
Are the technical standards for the Works: Contractor adopts as his specifications
Item numbers & procedures for accepting non-conforming product at a reduced level of service removed
Role of Superintendent became Principal’s rep
Annexure completed by technical experts 9

10. Specification Suite Restructure
The MRS documents will address all payment related Clauses for traditional contracts for example, item numbers and reduced level of service
The MRTS documents will address the technical standards required for the Works
One standard technical ‘core’ document for all projects
Both MRS and MRTS documents can have annexures
MRTS Annexure – eg specified standard for surface evenness
MRS Annexure – eg paying for a higher standard of surface evenness 10

11. Specification Suite Restructure
MRTS01 Cl 14:The Administrator shall be as stated in Clause 1 of Annexure MRTS01.1 with the role as defined in the Contract. Where not stated, the Administrator shall be
the 'Superintendent' as stated in the Contract for the following TMR contracts –
Road Construction Contract; Roadworks Performance Contract; and Minor Works Contract.
the 'Principal's Representative' as stated in the Contract for the following TMR contracts –
Design and Construct Contract; Design, Construct and Maintain Contract; and Alliance Contract 11

12. Summary
Extensive consultation process with stakeholders in TMR and industry (AAPA and CCAA)
Agreement have now been reached on most issues
Specifications / Technical Standards will be released shortly in new MRS & MRTS format
Upcoming sessions will inform delegates about the specification changes
Panel discussion sessions to follow the presentations
Binders and aggregates
Sprayed seals and asphalt
Put the improvements into practice
Learn about the implications of the changes
Understand the intentions of the specification writers
Ask questions for clarity and promoting smooth implementation
