The degree of compaction and CBR strength common been used to evaluate with the sta-bility and strength of Graded Broken Stone Base,The relationship between the degree of compaction and CBR has been not in-depth study.This article about the test that investgated the test section Graded bro-ken stone base of the construction yard engineering in Zhuhai.Obtained the relations between the degree of compaction and strength of CBR of the graded aggregate base.Gain the conclusion that the grading macadam base construction technology of compaction degree and the relationship between reference con-clusion.%压实度和 CBR 强度都可以用来评价配碎石基层稳定性和强度，但两者之间的关系需要深入研究。通过对珠海某在建堆场工程级配碎石基层进行试验，求得级配碎石基层压实度与 CBR 强度关系，并得出级配碎石基层施工工艺与压实度之间关系的参考性结论。
