In 1993, professor Michael Hammer of MIT and James champy co-author the book of Reengineering the corporation ----- a Manifesto For Business Revolution, put forward the concept of BPR. BPR's central thoughts is to redesign the business process, produces the valuable result, decrease cost, improve the quality, speed and service, finally improve the performance of enterprises from the customers' need taking the business process as reforming objective.

业务流程再造（Business Process Reengineering ――BPR）概念的提出是1993年，美国麻省理工学院迈可·哈默教授与詹姆斯·钱辟合著的《再造公司――企业革命的宣言》（Reengineering The Corporation ――A Manifesto For Business Revolution）一书，其概念的核心含义就是指从顾客的需求出发，以企业流程为改造对象，对企业流程进行根本性的思考和分析，通过对企业流程构成要素的重新组合，以此实现企业业务流程彻底的重新设计，产生出更为有价值的结果，在成本、产品质量、服务和速度等方面获得戏剧化的改善，从而获得企业绩效的巨大改善。

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.
