In Myanmar, the present standard of road infrastructure and design are based on British, in 1933.The study  areaof the  selected  road  is  Mudon-Kawkareik road.  Thisroad  is  part  of  the  Asian  highway  and east west economic corridor of the Asian region. 2015 will open the trade road net work of this region.  So,  Myanmarroad  infrastructure  must  be  prepared  for upgrade.  ManyAsian countriesfollow  the  AASHTO standard.  Mydepartment  want  to  change  the  AASHTO 1993 flexible design method. Therehas many parameter of effective soil resilient modulus, layercoefficients   and drainagecoefficient,   structural   number   serviceability index. Representativematerials  for  the  state  of  Mudon-Kawkareik  road  have  been  acquired  and fundamental testing wasdone todetermine their properties .All the materials showed good soil  classification.  A  series  of  laboratory  resilient  modulus  tests  were  performed  on  the whole  granular  sub  grade  soils  at  four  temperature  and  three  moisture  contents  using  the AASHTO   testing   procedure   .Prediction   equations   were   developed   to   determine   the resilient Module under Mudon-Kawkareik  environment and field conditions.Department  of  Highway  in  Myanmar  is  build  the  pavement  layer  design  by  calculating restricted  loading  in  accordance  withthe  standard  of  truck  factor  and  Equivalent  single axle  load  (ESAL)  or  Cumulative  number  of  standard  axle,  which  also follow  the  Road Note 31.A procedure to estimate the cumulative 18-kip ESAL was developed utilizing the weight in motion (WIM) data in Mudon-Kawkareik.Nowadays, the roads are damaging by a lot of reasons which is one of the main issues for every  country  on  flexible  pavement  which  are  not  in  good  quality  and  errors  occurs  in design  stage.  By  comparison  between  AASHTO  and  Road  Note  31  have  been  seen  the different thickness pavement design and different percentage cost of evaluations. It is also has seen the thickness of each layer for flexible pavement structural for both design methods.Flexible  pavement  thickness  design  is  very  useful  in  highway  engineering.Therefore comparing AASHTO and Road Note have gave the message about the best design which is appropriate to solve current situation.   aThesis (M.
