As shown in Fig. 1, the cushion is a layer of soft material, which is placed between the raft and the soil surface, to adjust stress distribution on the raft.
The length of pile is 5 m, the corresponding spacing of pile is 40cm, 50cm and 60cm, the material of cushion is coarse sand.
According to different material of soil and highway, the model is divided to several groups, containing fine sand, silty clay, mucky soil, cushion, embankment and pavement.

Biosorption is a process that involves the use of biological materials that form complexes with metal ions using their functional groups [6].
Bacterium secreted sticky material called EPS constituting proteins, polysaccharides, humic acids, and lipids that assisted cell adhesion, thereby should be helpful to initiate the aerobic granulation process [15].
