AAPA Q TMR Strategic Alliance Workshop
Delivering asphalt in Queensland – the future direction
1. EXECUTIVE SUMMARY The AAPA Q TMR Strategic Alliance workshop “Delivering Asphalt in Queensland – the future direction” focused on the need for improved value-‐for-‐money and the transfer asphalt design and performance responsibility to the Queensland asphalt suppliers.
Participants included AAPA, QTMR, ARRB and National Committees responsible for asphalt & pavements.
Facilitated by Alan McLennan with opening presentations on long, medium term developments and a review of the current situation in Queensland by QTMR and AAPA representatives. This was followed by breaking into three groups and first considering the “Desired future for asphalt supply in Qld” followed by the groups deriving “Long-‐term strategies” and “Short-‐term actions”.
“Desired future for asphalt supply in Queensland” Smaller government | Risks transferred to industry with an expanded role and increased capacity | Collaborative relationships with mutual respect | Long-‐term performance responsibilities of products | Increased sustainability | Attractive & leading edge | Flexible pavements more competitive on price/performance offering increased value for money.

3. SUMMARY OF PRESENTATIONS a. Presentation – Les Millar & Alan McLennan
Welcome & why the workshop: * Q biggest user of asphalt & full depth asphalt in Australia * TMR looking for increased v-‐f-‐m, cost effective & WOLC * Responsibility being transferred to asphalt suppliers for -‐ mix design & testing | based on production | performance improvements wanted | innovation * Asphalt projects have lower costs in other States * Opportunities to collaborate on cost efficiencies * Commitment to accept changes but need the long term vision
Operations of the day and the purpose, presentations as scene setting followed by workshop considering the future direction and the through smaller groups looking at long and short-‐term actions needed.
b. Presentation – Erik Denneman “Current and future developments in asphalt technology”
Conventional mix design – volumetrics by different methods | straight forward, experience, reliable on binder but no direct link to pavement design (PD), empirical, reactive International trend to performance related, properties needed in field, performance specified, simplified. Methods in USA, EU & Australia -‐ need work locally on PD link Current projects – HiMA, SMA design, PD & modulus/master curves, RAP and performance. HiMA or EME – good fatigue. Impermeable, high modulus = thinner pavements
c. Presentation – Bevan Sulllivan “Material Characterisation of Australian Asphalts”
Characterisation of Australian Asphalts – thickest in the world Fatigue endurance limit valid & accepted, design models poor. AAPA sponsored project – calibration local to international Dynamic modulus & master curves should be used, links to international, shows very high similarity in Australian mixtures. Provides proof of undervaluing of asphalt in current pavement design Delivers significant benefits and cost saving, can be applied immediately
AAPA Q TMR Strategic Alliance Workshop: Delivering Asphalt in Queensland – the future direction v3 page 6
d. Speaking notes – Peter Evans & TMR Asset Managers Change is coming – minimising costs, move to smaller government, want less risk, term maintenance.
Industry is already picking up responsibility.
TMR – due diligence (with Hyder) considering alignment of asphalt procurement with RMS, reducing involvement in mix design to design assessment and auditing. Defects liability to be increased beyond the current 90 days. Move to project funded audit with performance warranty from 12 to 24 mths. Removal of waterproofing seals when voids not excessive. Harmonisation of RMS & TMR specifications would have efficiencies.
Superior technical areas – volumetric assessment vs mass based assessment considered better, local specs work, source rock in NSW or higher standard than being used in Q, Q quarry management system has benefits, unlikely to be able to create a panel contract system in Q due to term maintenance contracts.
Change activities: Hyder considering options, RMS comfortable with their system and are unlikely to change, not possible to predict the final outcome, will work with AAPA but seems likely that Q will move to implement a similar system to RMS.
Feedback from TMR PD&O Asset Managers: Larry Mudge, Patrick Dennehy, Adam Garvin Need to remember the temperature difference between SEQ and North Queensland, direction of changes highlighted supported. The industry has discussed the desire to create mixes more performance based, suited to the area and would perform better. This should encourage innovation from industry and this is a step on the path to transferring greater flexibility & responsibility to industry.
Dougall Broadfoot: AAPA State Executive Officer NSW reported that RMS were moving very soon to term maintenance contracts which would impact on the viability of the panel contract for purchasing asphalt.
e. Presentation – Rob McGuire “Opportunities & challenges of potential changes for Q asphalt producers”
Current: low risk | low responsibility | limited need for tech staff | limited opportunities Opportunities: Taking responsibility with greater control | skills can be used | performance experience increased | easier innovation & v-‐f-‐m | easier Local Govt mixtures Challenges: Time needed to change | Skills scarce | Need to increase construction efficiency | TMR region differences Close: General Management keen to change | Must include |future needs | best to work together

Conventional mix design
Differs per road authority, bot nationally and internationally but typically: – Focus on volumetrics and specification of
components (grading, binder) Advantages:
– Straightforward – Decades of experience – Fairly reliable determination of optimum binder
content l Disadvantages:
– No direct link to pavement design methods – Empirical, reactive specifications
3 www.arrb.com.au Trusted advisor to road authorities for technical input and solutions
Directions in asphalt technology
Strong international trend towards performance related design Concept of performance specifications:
– Evaluate mix properties based on field loading conditions (climate, traffic) relevant to site.
– Describe required performance, rather than prescribing mix composition.
– Testing mostly mix and binder type blind. – Simplification: fewer, but more reliable tests, only one test per
performance parameter. – Reduces barriers to innovation and promotes efficient use of
natural resources, without sacrificing performance.

Delivering Asphalt in Queensland – “the Future Direction”
Speaking Notes for AAPA Workshop – Friday 5 April 2013 Background - Change is coming, and has already commenced.
Queensland Government is now focusing strongly on $, and previous DG was personally reviewing projects to minimise costs.
Move to smaller government. Herson Lab had 82 technicians two years ago – now 36. We
expect that this trend will continue.
Less tolerance for risk in Government – e.g. Health Department – problem sheeted home to Government even if issue arose with private supplier.
Strong desire from industry for consistency between states.
Move to term maintenance contracts – DDG has announced that new maintenance
contracts in SEQ will be performance based in 3 years. Unlikely that prime contractors will not pass on the warranty obligations to their asphalt suppliers.
TMR Response TMR currently working with a consultant Hyder to conduct “due diligence” on a proposal to
align the asphalt procurement process in Queensland with that used by RMS in New South Wales.
Under current arrangements, TMR currently is heavily involved in the mix design process for new asphalt mix designs, and conducts laboratory testing to validate mix designs. As such, TMR assumes partial responsibility for the final product.
As mentioned, with the 2012 reduction in laboratory staffing, (laboratory staff reduced from 82 to 36) and the coming retirement of a key staff member (Senior Principal Advisor (Materials Testing)) involved in the mix registration process, TMR is now unable to continue to adequately resource the current mix registration process. A 2012 backlog of mix designs in the TMR laboratory has now been largely addressed by temporarily reallocating staff, and negotiating with AAPA to have increased mix design testing performed by industry. However, within TMR there is a strong desire for future involvement in mix design assessment to be reduced to an auditing role.
The default defects liability period for asphalt in Queensland is 90 days. This reflects the joint responsibility for the product. However, it considerably increases the risk to the State of financial responsibility for premature failure, if defective asphalt ruts, ravels, bleeds or strips when exposed to rain for the first time after the first 90 days.
The RMS asphalt procurement system provides a 12 or 24 month warranty (moving to all 24 months) and much increased penalties for excessive voids than Queensland. RMS also has an extensive, project funded, audit program which tests asphalt from production.
Queensland currently requires a sealing layer between the surfacing layer and the structural layer, to address stripping if there are excessive voids. RMS does not require this layer, and have less expensive asphalt due to less disruption to paving and the cost of this seal.
Department of Transport and Main Roads Page 2 of 2
Harmonisation of asphalt specifications would align with a desire by industry for consistency between states.
Issues and Suggested Approach There are some technical areas where the Queensland approach is thought to be superior to
that in RMS. For example:
− Queensland controls binder content volumetrically, and this is believed to account better for rock of different Specific Gravity than the RMS system of specifying binder content.
− The specified properties and requirements are attuned to achieving adequate performance under Queensland conditions, which may not be achieved under those specified by RMS.
− There will be an economic need to amend some design parameters due to availability of better source rock in NSW than Queensland.
− Queensland has a quarry management system in place to provide assurance of quality particularly for our basaltic quarries which we would need to retain.
− RMS have a centrally managed panel procurement process for small asphalt jobs. With the change to road asset management contracts in South East Queensland, panel contracts could have a limited role here, so restricting scope to alignment of technical specifications and warranties would appear to present best value for TMR.
The current work with Hyder is identifying these differences in approach and working through their implications. One approach would be to modify the RMS system (and clearly identify the changes) where good technical or economic reasons exist, rather than try to change the TMR system. RMS are comfortable with their system and envisage little change going forward.
A small group of TMR engineers and laboratory staff have recently met with RMS staff at Ballina in NSW. The impression gained was that RMS staff are very comfortable with their current approach to procurement of asphalt, and believe that they are consistently achieving well performing asphalt.
Although there would appear to be obvious benefits in aligning more closely with the RMS process, the TMR “due diligence” process is still underway, and it would be premature to predict the final outcome.
TMR will work closely with AAPA to keep them informed of the likely changes and to agree on a timetable for implementation. However, at this stage, it seems likely that Queensland will move to implement a similar system to RMS.
