Abstract:

 The materials  constituting  the  pavement  bodies,  until  today,  have been   limited   to   certain   so-called  noble   materials   (rolled   sands, aggregates,  etc.),  but  these  are  in  the  process  of  being  exhausted under  the  effect  of  intensive  exploitation  and  the  scarcity  ofquality quarries.With  the  objective  of  preserving  the  deposits  of  aggregates in  the  process  of  exhaustion  for  future  generations  and  of  exploiting the aeolian sands in abundance in the regions of southern Algeria, we aim to  enhance  the  latter  in  the  bodyof  the roadway  mixed  with the tuffs, this would imply a reduction in construction costs (use of local aggregates of lower quality available in large quantities, reduction in transport  costs).  From  an  environmental  point  of  view,  this  would limit  the  impacts  with  a  reduction  in  CO2emissions  linked  to transport.In  this  work,  we  applied  a  new  approach  based  on  the technique  of  mixtures  to  valorize  and  exploit  the  sand  of  dunes existing in abundance, with the treatment in hydraulic binders, which allowed us to go up to 20% of sand dunes.
