Unachieved Maximum Dry Density (MDD) Value for Compaction 2

[andrewsugi]

Dear All,

I have a problem with unachieved compaction at its MDD value. As written in company specification, base course of road shoulder compaction must achieve at minimum 98% of its MDD. Unfortunately, the sand cone test result taken at site showed that the MDD value only achieved at least 96%.

Do any you have any suggestion of how to show the company that 96% MDD value is actually good enough for base course?

@LRJ and @Ron:: OK! Thanks for the input!
