The investigation showed that Buon Ho road has suffered significant and rapid deterioration leading in places to complete pavement failure, but that the pavement condition is not uniform and there are significant lengths with only slight or moderate deterioration and other areas where no deterioration is evident.
In situ DCP testing was undertaken on pavement layers within the inspection pits where appropriate. Slight loss of fine aggregate Poor pavement and shoulder cross-fall impeding run-off Severe defects in WBM shoulders with ruts and related shoving, some areas.
Taking into account the surveyed strength of the existing gravel road; 21-092 current local standard designs and recent SEACAP studies4 the conclusion 22tcj be drawn that the Buon Ho pavement designs were adequate for their original intended purpose. 210-922 in very bad condition — essentially pavement has lost seal and lost integrity with severe ruts and loosening of base material.
