两种常用的路基压实度检测方法

Two Kinds of Common Detection Methods of Subgrade Compaction

灌砂法和核子密度仪法是道路路基压实度检测中常用的两种检测方法。这两种方法应用范围比较广泛,且能够获得较高的检测精度,有利于道路工程施工质量控制。鉴于此,结合施工现场中的路基压实度检测,对两种检测方法的原理做出了分析并对两种检测方法进行对比,可为相关工作提供一定的参考与借鉴。

Sand replacement method and nuclear density instrument are detection methods which commonly used in road subgrade compaction detection. The methods have abroad application scope and they can obtain high detection accuracy which is good for the control of road construct quality. Given this, this paper analyzes and compares the principles of the two methods combined with the subgrade compaction testing in construction site to provide certain reference for associated works.
