AAPA  and  Long  Life  Asphalt  Pavements  in  Australia

§ LLAP  Projects  and  studies  between  AAPA  and  SRA’s  since  1980’s§ Regular  positive  reports  on  the  studies  -­ Sharp  &  Tepper  2001  -­ Youdale  2004  -­ Foley  2008  -­ Rickards  2009  -­ Armstrong  &  Rickards  2010

§ Great  reports  but  nothing  changes!  Austroads  revisions  delivering  conservative  outcomes  

§ Over  designed  but  by  how  much?  § This  project  changes  that  forever§ Absolutely  about  innovation  driving  value

What  makes  AAPA  tick?  Drivers  of  AAPA  Innovation

§ AAPA  is  the  peak  body  representing  all  parts  of  the  flexible  pavement  industry  in  Australia  since  1969. Member  categories  embrace  bituminous  binder  suppliers,  asphalt  producers,  sprayed  sealing  operators,  equipment  suppliers,  consulting   firms,  toll  road  operators,  all  State  Government  Road  Authorities  and  many  Local  Governments  across  Australia.

§ Mission  – to  effectively  represent  the  interests  of  all  members and  to  demonstrate   technical  excellence  in  the  sustainable  use  of  bitumen-­based  products  in  pavement  engineering  solutions

§ Values  – in  all  its  activities  and  at  all  times  AAPA  and  its  members  will  act  with  professionalism,  honesty  and  integrity

Consideration  of  Value  Perceptions

§ Value?  More  benefits  for  less  or  same  costs?§ Benefits?  Not  universally  perceived  e.g.  Smoothness  e.g.  Noise§ Costs?  Impacts?  Whole  of  life  assessment?§ Value  for  money  outcomes  are  defined  by  those  motivations  clients  regard  as  benefits§ Our  drivers  give  us  the  clear  goal  to  innovate  and  seek  out  innovations  that  provide  value  solutions  in  terms  of  meeting  the  goals  of  our  clients

§ Community  expectations  – OUR  Challenges  – this  project§ Freeways

§ Free  flowing  (safe  system  guidelines)§ Smooth  to  drive  on  – with  low  noise§ Safe  -­ no  spray  when  it  rains,  good  skid  resistance§ Well  maintained

Project  Nurturing  -­ Engagement  with  SRA’s  and  ARRB

§ Early  stakeholder  engagement§ Project  Steering  Group§ Dynamic  Modulus  v  Resilient  Modulus§ Sample  compaction  method§ Healing  and  NCHRP  Project  9/44§ Plant  mixed  samples§ Over-­reliance  on  NCAT  data§ UK  data  and  curing§ FEL  incorporation§ Field  validation§ Composite  &  other  pavements

Value  Deliveries  of  the  Project?

§ Safety§ Cost  effectiveness§ Sustainability§ Innovation§ Harmonisation§ Smoothness§ Whole  of  life  benefits§ Maintenance

§ Traffic  at  maintenance  plus  texture  &  spray§ Pavement  thickness  savings  plus  time§ Virgin  material  savings  plus  recycle  &  noise§ Australian  &  state  of  the  art  internationally§ Applicable  nationally§ Initial  and  perpetual  via  mill  &  fill§ Smooth,  fuel  savings,  congestion  avoided§ Limited  to  the  wearing  course  – perpetual  pavement

Project  Outcomes  – Takeaways  

§ This  work  has  never  been  done  before  in  Australia  – uniquely   field  validated§ It  was  broadened  &  enriched  by  SRA  and  ARRB  input  &  undertaken   in  close  collaboration

§ It  has  been  peer  reviewed  as  being  work  of  eminent  international  quality§ The  benefits  it  contains  for  asset  owners  and  road  users  can  not  be  ignored  –in  terms  of  cost  &  sustainability

§ Six  for  the  cost  of  five§ Most  timely  given  the  infrastructure  boom§ Implement  nationally  quickly  -­ Bevan’s  following  papers

Learning  Points  for  Future  Value  

§ Early  engagement  highly  beneficial  and  across  the  right  levels§ Open  exchange  and  sharing  of  objectives  and  information§ Develop  and  maintain  a  bias  for  action  with  supporting  performance  criteria§ Focus  on  technology  transfers  for  earliest  achievement  of  the  value  benefits§ Gain  commitment  to  national   implementation  at  the  outset§ Literature  surveys  not  always  needed  as  paid  research§ Express  project  linkages  to  Asset  Owner  vision  elements§ Identify,  measure  and  tell  community  benefits  of  project§ Planned  and  targeted  communications  and  reviews§ Great  value  gains  from  international  affiliations  § Just  keep  looking  and  doing  it  for  ongoing  improvements
