Mudstone filled roadbed structure and construction method thereof
The invention relates to a mudstone filled roadbed structure and a construction method thereof. When the roadbed is constructed in a mudstone developing area, a water collecting tank is arranged in a soil base, a waterproof layer is paved on the surface of soil base, a mudstone layer is constructed on the waterproof layer, a water-sealing leveled layer is constructed on the mudstone layer, a leveled acceptance layer is constructed on the lower embankment, and a modified soil layer is paved on the road bed. The roadbed is pressed by a crusher, a bulldozer, and sheep-foot roller and is pressed by a layering vibrating press technology and a punching supplement pressure technology. Through controlling the size and uniformity of mudstone particles, the overall stability and strength of roadbed are improved, and the uneven settlement of roadbed is reduced. Moreover, the phenomenon that mudstone is softened by water and is converted into mud is avoided. The engineering quality can be guaranteed, and at the same time, the modified soil bed can meet the related acceptance standards. The practices have proven that the provided method can achieve a good technical effect in mudstone roadbed construction.
