ABSTRACT
In the construction of highways in the mountainous areas of northern China, large-sized fillers are often used for roadbed construction, and the quality inspection of the roadbed often becomes a difficult problem. In actual construction, the settlement difference method is often used to control the quality of subgrade, and this empirical method cannot accurately mark the quality of concrete subgrade filling. In order to solve this problem, the GeoGauge method was introduced to conduct comparative experiments to obtain accurate construction quality data. The regression analysis method is used to study the quantitative correlation between the Young's modulus and the settlement difference. And it finally came out with the standard value for process quality.
