道路翻浆的原因 (1)道路土壤是粘土,在结冻初期因地下水毛细上升作用,使路基土壤含水量过多,冻结很深时发生膨胀,解冻时上层初化、下层尚陈结,水分不易渗透、蒸发、排除,故产生翻浆。 (2)地下水位高,路面遭受破损,地面水渗入路基内,或地下排水设备不够完善,使地下水不能及时排除,或因地下埋设之上、下水道漏水,这样就使路床含水量过多,因而造成翻浆。
Reasons of Road Spreader (1) The soil in road is clay, which is caused by capillary rise of groundwater in the early stage of freezing, which causes excessive water content in subgrade soil. When the soil is frozen deeply, the upper layer is initialized while the lower layer is still clogged. Penetration, evaporation, elimination, it produces a turbulence. (2) groundwater level is high, the pavement is damaged, surface water seepage into the subgrade, or underground drainage equipment is not perfect, so that groundwater can not be excluded in time, or buried underground, sewer leakage, so make the roadbed too much water, Thus resulting in airing.
