[摘要] 在公路、铁路等工程中，对填土路基进行适当碾压，是保证路基施工质量的重要环节。碾压次数不够会影响路基质量，同样，次数过多不仅不经济，也有可能降低土体强度及刚性，带来负面影响。介绍了新开发的一种落球式便携刚性检测仪，可以快速地测试碾压后的土基压缩弹性模量，进而有效地对填土碾压质量进行管理。

Abstracts: In engineering, it is an important key, though compressing the foundation of filling, to guarantee the construct's mass of road foundation. The times of compressing will of Fect the quality of compressing mass. Adopting the machine EH-FWD-B which was developed by Sichuart Central Inspection Co., Ltd, through testing the modulus of compression can manage the compressing mass of filling validly.
