Description

On  1  March  2008,  the  product  standards  in  the  NF  P  series  will  bedefinitively  withdrawn  and  replaced  by  the  new  NF  EN  Frenchstandards derived from European standardization.  This  document  explains  the  nomenclature  and  formulation  of  themixes generally used in France and how they correspond to Europeanstandards. It also sets out the stages of the French mix design process. The  series  of  European  standards  covers  French  mixes  and  othersbesides, for wearing courses, base courses and sub-base and road baselayers.  It  is  therefore  necessary  to  present  the  information  in  theEuropean  standards  to  make  it  suitable  for  application  in  the  Frenchcontext This technical guide makes it possible to perform this transcription. Itis  divided  into  a  number  of  sections  which  explain  the  references  tostandards,  the  bituminous  materials  used  in  France,  the  type  tests  formixes,  the  characteristics  of  the  aggregates,  the  fines,  the  coatingbinder and the use of reclaimed asphalt. The guide does not deal withrecommendations  for  laying,  but  explains  where  this  information  canbe found.  The  guide  ends  with  a  series  of  Annexes  containing  tables  thatsummarize  the  mix  formulations,  the  minimum  characteristics  of  theaggregates,  the  performance  that  is  expected  of  the  various  types  ofmix, ending with a reclaimed asphalt information sheet.
