Connected with cross section patterns of freeway, the design method of drainable base course system and edge drainage system which meet to request are given too. The aggregate grading and mixture ratio of porous cement-treated macadam are obtained based on accurate survey on material properties and lots of laboratory experiments. After the construction of experiment road, a summary of mixing, spreading, roller compaction and maintenance process about subsurface drainage system is made, and the analysis on the cost of construction about drainable base course is also carried. According to the test of coefficient of permeability, porosity and strength of compression about local test samples and core samples, the paper concludes that main performance index of subsurface drainage system has achieved the design anticipated effect.
