Abstract: Through lab experiments, material requirements, mixture ratio, method of compacting, strength characteristics and resilient modulus in compression of the large pores cement treated permeable base were studied. The conclusions were as follows: selection of maximum grain size of aggregates should be based on the drainage layer^s thickness and structure strength requirements; cement content, C /A and volume of entrapped air Va would be significant factors in affecting the compressive strength of the large pores cement treated permeable base; the static compacting method of test sample should be adopted in constructing large pores cement treated permeable base instead of vibrant compaction; aggregates with lower crushing value were required

Key words: permeable pavement, cement treated permeable base(CTPB ), mix ratio, strength, compress modulus
