Abstract: This article introduces a new type of rapid detection technology of soil material characteristics-G-STAB system (referred to as falling ball detection technology). This technology is based on Hertz impact theory. By measuring the contact time between the falling ball and the ground, the automatic analysis software is Indexes such as the deformation modulus, foundation coefficient, and maximum compression of the test object can be calculated. A large number of indoor soil trough tests and field measurements have fully confirmed the test accuracy of the method and the good correspondence with the results of the plate load test, and can effectively guide the optimization of material grading, water content and rolling times during the filling process. The characteristics of falling ball detection technology are fast, effective, and low cost, which can well meet the comprehensive and real-time control of road engineering fill construction quality. In the construction of road filling works and subgrade works, strict and effective quality management of rolling quality is an important link to ensure road quality [1]. At present, the detection technology and equipment used in China are time-consuming and labor-intensive, and the sampling rate is very low. The detection results cannot accurately reflect the overall quality of road construction. On the other hand, the management of construction quality is not only the quality inspection during delivery and acceptance, but more important is the quality control during the construction process. Due to the lack of fast, effective, and low-cost detection technology, it is difficult to achieve real-time detection of the construction process. In order to effectively solve the construction quality process control of large-scale construction sites, the development of fast and effective detection technology is an important issue to be solved urgently to ensure the construction quality of road engineering.

The rapid detection system G-STAB (abbreviated to falling ball detection technology) developed by Japan Co., Ltd. (Tokyo) can quickly and accurately detect various types of soil materials (clay, silt, sandy soil, gravel, improvement) The deformation performance and other mechanical properties of the soil, etc., and the test operation of this technology is very simple, just drop the sphere, the analytical calculations are all carried out automatically, and the working efficiency is extremely high (about a few seconds). Therefore, a small number of people can manage a large-scale construction site, and implement effective real-time inspection and control of the construction quality of roadbed filling and improved soil.
This technology is widely adopted by organizations such as roads, environmental departments, and power companies in Japan. In China, Sichuan Shengtuo Testing Co., Ltd. has obtained all rights related to the technology and has begun to produce equipment related to the technology.
