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.

结合高速公路横断面型式，提出了适合要求的排水基层排水系统和边缘排水系统设计方案；在进行详细材料调查和大量室内试验的基础上，提出了多孔隙水泥稳定碎石基层的集料级配和混合料配合比；修建了路面内部排水系统试验路，根据试验路工程的施工情况，对路面内部排水系统施工的拌和、摊铺、碾压和养护工艺进行了总结；并对排水基层造价进行了分析；通过对现场取样试件、芯样的渗透系数、孔隙率和抗压强度的测试，证明路面内部排水系统的主要性能指标均达到了设计预期的效果。

Our other primary insurers delivered their usual fine results last year. These operations, run by Rod Eldred, John Kizer, Tom Nerney, Michael Stearns, Don Towle and Don Wurster had combined premium volume of $579 million, up 40% over 2000. Their float increased 14.5% to $685 million, and they recorded an underwriting profit of $30 million. In aggregate, these companies are one of the finest insurance operations in the country, and their 2002 prospects look excellent.

我们其它初级的保险公司去年的表现依旧出色， Rod，由 John， Don， Tom， Michael 等人带领的各家保险事业，总计贡献了 5.79 亿美元的保费收入，较 2000 年成长了四成，浮存金则增加 14.5%成为 6.85 亿美元，外加 3，000 万美元的承保利益，总的来说，这些公司堪称全美最好的保险公司之一，展望 2002 年他们的前景依然可期。

In aggregate, our smaller insurance operations produced an excellent underwriting profit in 2000 while generating significant float - just as they have done for more than a decade. If these companies were a single and separate operation, people would consider it an outstanding insurer. Because the companies instead reside in an enterprise as large as Berkshire, the world may not appreciate their accomplishments - but I sure do. Last year I thanked Rod Eldred, John Kizer, Don Towle and Don Wurster, and I again do so. In addition, we now also owe thanks to Tom Nerney at U.S. Liability and Michael Stearns, the new head of Cypress.

总的来说，其它规模较小的保险业务在2000年产生了可观的承保利益，同时一如过去十年来持续贡献大量的浮存金，如果把这些公司视为单一独立的企业，那么他们绝对可以称得上是一家经营绩效优异的保险公司，而因为这些事业隐身在Berkshire如此庞大的事业体中，外界无法理解他们的努力与成就，但至少我个人能够深深地体会地，去年我感谢过Rod、John、Don等人，今年则还要再加上美国责任险的Tom以及Cypress的新任主管Michael。
