In Situ Research on the Spatiotemporal Variations in the Temperature and Deformation of Aeolian Sand-Modified Soil Roadbed Constructed in Cold Regions

Table 1

Lag days of the minimum soil temperature relative to the minimum air temperature, the embedded depth of the monitoring sensor, and the variation range of the soil temperature.

Sensor number	Lag days (d)	Depth (m)	Minimum soil temperature (°C)	Variation range of the soil temperature (°C)
H1-F5-L1-TS	2	0.2	−11.2	−11.2 to 9.7
H1-F4-L7-TS	15	0.5	−10	−10 to 9.8
H1-F2-L3-TS	38	2.0	−9.3	−9.3 to −1.3
