which type of roller required to compact crushed stone base

[defg]

Which type of a roller is required to compact a crushed stone base(CRR)specified norminal degree of compaction is 104%by the use of BS-Heavy.Also Iwould like to know how many passes will be required to achieve the spcified degree of compaction?The maximum dry densities achieved from that crushed rock by proctor testing ranges from 2220kg/cum to 2230kg/cum.In addition to this the specification specified two method of Acceptance limits in respect of field density,which are Aggregate apparent density(88) and BS-Heavy(104)which is appropriate and the best among the two methods?Please assist on this.
