     Pavements  are  engineered  structures  essential  to  transportation,  commerce  and  trade,  and  everyday  life.  In  order  for  them  to  perform  as  expected,  pitt&sherry  would  ensure  implementation  of  different  methodologies  and  practices  in  order  for  pavement  to  be  designed,  constructed,  maintained,  and  managed  properly.        Our  single  most  valuable  asset  is  arguably  the  pavement  structure  within  our  infrastructure  network.  We  understand  that  pavements  are  subjected  to  static  and  dynamic  loads  as  well  as  exposure  to  the  elements,  therefore  only  sound  engineering  judgment,  from  experienced  and  qualified  personnel  can  provide  cost  efficient  and  appropriate  solutions  to  our  pavement  challenges.  pitt&sherry  demonstrates  an  innovative,  sustainable  approach  through  relationships  with  research  centers  of  excellence  across  the  globe.  pitt&sherry’s  teams  undertake  investigation,  analysis,  design  and  documentation  services  for  the  construction,  rehabilitation  and  strengthening  of  pavements.  

   pitt&sherry  demonstrates  an  innovative,  sustainable  approach  through  relationships  with  research  centers  of  excellence  across  the  globe.  pitt&sherry’s  teams  undertake  investigation,  analysis,  design  and  documentation  services  for  the  construction,  rehabilitation  and  strengthening  of  pavements.  pitt&sherry  specialist  pavement  engineers  understands  the  variables  that  pavement  performance  is  affected  by  materials,  environment,  loading  and  construction  as  well  as  structural  design  –  and  it  is  the  variability  in  these  attributes  that  introduces  risk.  To  manage  and  quantify  these  risks,  pitt&sherry  has  developed  different  approaches  to  pavement  design,  embracing  fundamental  materials  analysis,  climatic  conditions,  actual  loading  regimes  and  latest  developments  in  pavement  design  philosophy.  Life-­‐cycle  cost  analysis  is  one  of  the  tools  that  pitt&sherry  is  adopting  in  which  pavement  structures  are  evaluated  and  assessed  to  be  presented  to  our  pavement  asset  owners.  The  life-­‐cycle  cost  of  a  road  includes  the  money  spent  on  initial  construction  of  a  road,  maintenance  over  its  lifetime,  and  the  

costs  to  users  for  their  delays  during  maintenance  and  reconstruction.    pitt&sherry  is  also  engaging  in  developing  more  durable  road  designs  solution  and  implementation  of  new  types  of  pavement  in  Australia  include  but  not  limited  to:  High  Modulus  Asphalt  (EME2)  as  a  substituting  of  conventional  dense  graded  materials  on  heavily  trafficked  high  priority  highways  and  motorways  aiming  to  enhanced  fatigue  and  deformation  resistance  and  increased  constructability.  

•   Thin  Overlays  (Thinlays)  to  pavement  preservation  and  their  ability  to  provide  improved  ride  quality,  reduce  pavement  distresses,  maintain  surface  geometrics,  reduce  noise  levels,  reduce  life-­‐cycle  costs,  and  provide  long-­‐lasting  service  

•   Crumb  Rubber  Sprayed  Seal  Binder  and  its  significant  environmental  advantage  using  recycled  tyres  to  modify  bitumen.
