摘要

尽管击实试验是目前最流行的室内土体压实试验方法，但实际上与现场任何一种压实方法都无相似之处，且不适用于无粘性土（粒状土）的压实试验。无粘性土的振动击实试验方法也存在很多问题。现代重型压实设备的使用，路基粒状填土的压实密度达到了目前室内规范试验方法不可能达到的水平。介绍了美国采用供高性能沥青路面混合料设计与质量控制之用的旋转压实机对粒状土进行的压实试验。其结果表明，旋转压实试验能有效模拟路基粒状填土的现场压实特征；可采用压实压力200 kPa、旋转角为1.25°、旋转次数为90、旋转速度为20 rpm的试验结果来控制粒状填土路基的现场压实质量。

Abstract

Although it has no similarity to any type of field compaction method，the Proctor compaction test is by far the most popular laboratory testing method

and it is widely accepted that the proctor compaction test is ineffective for cohesionless soils. Vibration compaction test for cohesionless soils needs to be improved for the practical applications. Due to the application of much heavier earth moving and vibration roller compaction equipment

soil densities compacted in the field are reaching levels that are not attainable in the laboratory. This paper introduces the test results of the gyratory test procedure conducted with Servopac gyratory compactor with 200kPa vertical pressure

1.25 degree gyration angle

90 gyrations

and 20 gyrations per minute，and the test results show considerable promise to be the construction specification for the quality control of field compaction for granular soils.
