The invention belongs to the technical field of
road construction, and particularly relates to a road base material based on multi-element
solid waste as well as a proportion confirmation method and application thereof. The preparation method comprises the following steps: S1, preparing raw materials; s2, determining the blending proportion of the steel
slag; s3, according to a
volume filling principle, calculating the dosage of the steel
slag, and according to the porous characteristic of the steel
slag, calculating the
void ratio of the formed steel slag with different particle sizes; s4, rubber particles wrapped by
cement mortar and
copper tailings are filled in pores in the surface of the steel slag, and the volume ratio of the volume of the
cement mortar to the volume of the steel slag is calculated by combining the influence of the expansibility of the steel slag on volume parameters; s5, calculating the use amount of the
copper tailings and the use amount of the
cement mortar; s6, the rubber particles absorb the steel slag to expand and deform, and the rubber particle dosage is calculated according to the relation between the steel slag
expansion rate and the rubber particle elongation. The volume design method is adopted, the influence of the steel slag
expansion rate is considered, the use amount of the road base material is calculated, the stability of the base material is ensured, and meanwhile good strength is achieved.
