Embodiment 1
[0046] According to an embodiment of the rubber powder modified cement stabilized gravel mixture base pavement structure of the present invention, it comprises asphalt concrete pavement surface layer, rubber powder modified cement stabilized gravel mixture base, cement stabilized gravel mixture base, grade With gravel subbase and soil foundation. The thickness of the cement stabilized gravel mixture base layer in the rubber powder modified cement stabilized gravel mixture base pavement structure is 20 cm, and the compressive rebound modulus is 2000 MPa. The thickness of the base layer of the rubber powder modified cement stabilized gravel mixture is 20cm, and the compressive rebound modulus is 1000MPa.
[0047] The asphalt concrete pavement surface layer includes an upper layer, a middle layer, and a lower layer, and the thicknesses are 6, 8, and 10 cm respectively. The upper layer is the upper layer of fine-grained asphalt pavement (in this embodiment, it is the layer of fin...
