The principle and effect of impact compaction , and its application in rockfill subgrade is introduced in this paper 并对冲击压实的作用原理，压实功效以及冲击压实在填石路基中的应用作了介绍。
The optimum passes of impact compaction is also described , which can be referenced by the implement of impact compaction technique 找出了冲击压实的最佳压实遍数，为冲击压实施工技术提供了参考。
Standard test method for bulk specific gravity and density of compacted bituminous mixtures using automatic vacuum sealing method 用自动真空密封法测量压实的沥青混合料的毛体积比重和密度的标准试验方法
Design and manufacturer the composite equipment what be used in the test . the parameter of equipment can be continuously adjusted in a large bound 压实技术的理论研究，重点观察和分析了土壤在振动与冲击联合作用下被压实的机理。
Standard test method for determining the effect of freeze - thaw on hydraulic conductivity of compacted or undisturbed soil specimens using a flexible wall permeameter 使用一柔壁渗透计对压实的或非分散性土壤样品液体导电性冻融效果测定的标准试验方法
Impact compaction machine is a pressing machine with high impact energy and it changes vibratory compaction from high frequency low swing to high swing low frequency 摘要冲击压实机是具有高冲击能量的压实机械，它将振动压实的高频率低振幅改为高振幅低频率。
The resulting landscape is dominated by impervious surfaces ? parking lots , roads , sidewalks , rooftops and construction sites compacted by heavy equipment ? that do not let water soak through 最后形成的景观就是由不透水的地面所主宰停车场、道路、人行道、屋顶，以及由重型机械压实的建筑工地，水都无法渗入这些地方。
By the analysis of the compact effectiveness on clay and sandy soils , it is proved that impact compaction is good for compacting the subgrade in deep depth and the effect on clay is better than that on sandy soil 通过对砂土和粘土两种不同土质路基的冲击压实效果的分析，验证了冲击压实的深层压实效果，发现粘土比砂土的冲压效果好。
Thirdly discussing the rationality of design indexes and the restricted zone , searching the relationship between the effect and beat numbers of marshall , founding the relationship between specimens made by gyratory compactor and by marshall compactor 并对superpave控制混合料的体积指标、禁区和控制点存在的必要性、马歇尔击实次数对击实效果的影响、马歇尔击实试验和旋转压实的关系进行了探讨。
