Abstract
Moisture content is a very important parameter in earthwork filling. In the process of earthwork compaction, the moisture content of the compacted soil shall be measured in time, and the moisture content shall be compared with the design requirements to check whether it is qualified. However, the conventional drying method usually takes about 6 to 8 hours, which will have a great impact on the construction progress. Therefore, this paper mainly discusses the alcohol combustion method in the construction site to temporarily replace the drying method to determine the moisture content of soil. The optimum sampling quantity, combustion times and the range of moisture content of alcohol combustion method are obtained. Finally, it shows the accuracy of alcohol combustion method in the temporary determination of soil moisture content in the construction site.
