Abstract：Miscellaneous soil refers to the filling of a large amount of construction waste, industrial waste or household waste, when the road route must pass through the area, if not processed will seriously affect the construction of road works. In this paper, the mechanical properties of the different reinforcement methods of the miscellaneous soil are studied, and the intensity and deformation change law of the reinforcement of the miscellaneous soil are studied by the experimental index of the pressure strength, cracking strength, rebound ingesting modulus, CBR value and organic matter content. Through the indoor test, the comprehensive strength, carrying capacity, anti-deformation ability and economic index of the reinforced landfill were compared with the analysis, and the experiment proved that the reinforcement effect of 0.08% content curing agent was the best. The results can effectively reduce the harm caused by road landfill to the safety of highway foundation and improve the availability of highway landfill. Keywords: miscellaneous soil; curing material; mechanical properties; comparative evaluation
