In virtue of the particularity of structure layer, the sample molding and design ways are different from the one for surface layer of mixes. Through parallel trial studying Marshall hit and circumrotate press molding, traditional Marshall design method and mechanics index method, the paper brings forward the molding and design method adapting to different types of ATBs.

由于其所处结构层的特殊性，试件成型方法、混合料设计方法均与沥青混合料面层有所不同，通过对比研究马歇尔击实成型和旋转压实成型、传统马歇尔设计方法和力学指标法，提出了适合不同沥青稳定碎石基层混合料类型的成型和设计方法。

It became more cliffy when we got more and more high.

越往上坡越陡，脚下坚实的泥土开始被最让我害怕的大大小小的&碎石山&蔓延开来，一直到翻过山后都是如此，好在昨天的经历给我狠狠的上了一课，今天根本不敢大意，一路狂奔下来，还能拍拍停停，倒也安然无恙。

But in many reinforcement projects, some unfavourable geological are encountered frequently, such as colluvial soil, residual soil, slope wash, etc., which result in collapse of borehole and clip of bore rod during drilling of borehole that will bring considerable difficulties to construction and many incipient faults for construction quality.

但是，锚固工程常遇到各类不良地层（例如塌积、残积、坡积和崩积层等碎石土地层），在锚固施工的钻孔中由于严重的塌孔、卡钻，给施工带来很大困难，同时也给锚固工程质量带来隐患。

And whether the pavement distress subimage model is right is determined according to length of pavement distress subimage model's connexity.

通过实验证明，该方法可有效地剔除路面破损子块模式矩阵中由于一些如路面杂物、碎石等噪声导致的野点

Muddy rustic alley, slope of cragged clastic rock, even the iceberg snow peak that firn does not have genu has their strong and vigorous figure, they comprehend themselves with their double foot, comprehend whole world.

泥泞的乡村小路，坎坷的碎石坡，甚至积雪没膝的冰山雪峰都有他们矫健的身影，他们用自己的双脚感悟自己，感悟整个世界。

Hall says one possible safety measure is placing a surface called "crushable concrete" at the end of the tarmac to help stop runaway airplanes.

Hall 说其中可能的安全措施是在碎石和沥青混合的表面铺一种叫&可挤压的水泥&，这种水泥可阻止飞机冲出跑道。

All says one possible safety measure is placing a surface called " crushable concrete" at the end of the tarmac to help stop runaway airplanes. He said several U.S.

说，一个可行的安全措施是在柏油碎石飞机跑道末端的表面铺设一种叫做&可压混凝土&的材料来防止飞机脱离跑道。

In this thesis, the engineering property of the frozen earth in the frozen railway roadbed in Anduo section (between DK1561+975-DK1562+530) of Naquhe region of Qinghai-Tibet railway was studied indoor. The change of engineering property of the earth samples with different water content , density and temperature were researched. The influence of concentration of the diffluent salt to the frozen strength was pilot studied. The thermal conductivity of the soil was experimented. With the result and data of the tests, the earth temperature field in Anduo section was demonstrated by numerical analysis, the structure parameter of the spall revetmentd and the rubble berm was given, the stability of the railway roadbed was evaluated.

本文以青藏铁路格尔木-拉萨段那曲河地区安多段(DK1561+975～DK1562+530)冻土路基为对象，对该地区冻土的工程性质进行了室内试验研究；对不同含水率、不同压实度的土样，研究在特定温度变化范围内工程性质的变化：初步分析了易溶盐含量对冻结强度的影响：测试了土样的导热系数；在室内土工试验的基础上，根据测试结果和数据，对安多段区域地温场进行了数值模拟，分析了该工点区间内合理片石护道、碎石护坡结构参数，评价了路基稳定性。

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。
