Aeolian sand nature of the road is not like ordinary clay road or rock construction, wind-induced sand subgrade has what kind of construction process?

Due to the different water conditions in the region, in arid areas, groundwater lacks the area, filling the roadbed with aeolian sand, in the best water content under the conditions of wind and sand compaction is unrealistic. According to the (T0131-93) heavy compaction test in the "Highway Geotechnical Test Procedure" (JTJ051-93), the maximum dry density was obtained. It was found that the aeolian sand had a maximum dryness when the water content was zero and the optimum water content Density of the peak. Therefore, according to regional water conditions, can be divided into dry construction and saturated water construction of two processes. The determination of the maximum dry density of the two processes is also different. Dry vibration method: the area of ​​water shortage in the region, the use of aeolian sand in the water content of zero when the maximum dry density, the maximum dry density as aeolian sand in the natural water content under the state of compaction of aeolian sand construction quality control The

Saturated water vibration method: the area of ​​sufficient water, with the best moisture content of aeolian sand when the maximum dry density. The maximum dry density is used as the construction quality control of the pavement compaction of the pavement in the construction of the embankment....
