Embodiment 2
[0053] This embodiment discloses a working method of the permeable asphalt pavement seepage attenuation model test system described in Embodiment 1: comprising the following steps:
[0054] Step 1: Lay the asphalt pavement sample in the sample tank, specifically, lay a graded crushed stone layer on the geogrid, and lay a porous cement stabilized crushed stone layer on the graded crushed stone layer, and the porous cement stabilizes the crushed stone layer. The lower layer of asphalt is laid on the stone layer, and the upper layer of asphalt is laid on the lower layer of asphalt to complete the laying of the asphalt pavement sample.
