Abstract

The invention discloses a road material produced by using Bayer process red mud, which comprises a road base layer, a road cement stabilized gravel layer and a road surface layer, wherein the road base layer is manufactured by the following raw materials according to weight percentage: 4-25 of low-temperature ceramic curing agent, 45-96 of red mud and 0-30 of aggregate, the road cement stabilizedgravel layer is manufactured by the following raw materials according to weight percentage: 8-20 of low-temperature ceramic curing agent, 10-20 of red mud and 60-82 of aggregate, and the road base layer is manufactured by the following raw materials according to weight percentage: 10-30 of low-temperature ceramic curing agent, 2-10 of red mud and 60-88 of aggregate. The invention has the beneficial effects that the Bayer process red mud with pollution to the environment is changed into road materials, therefore, a great amount of natural resources used during the roadway building process are saved , and the cost of road engineering is saved.

Description

technical field

[0001] The invention mainly relates to the technical field of traffic, in particular to a road material produced by using Bayer process red mud. Background technique

[0002] Red mud is the solid waste slag discharged during the alumina production process. According to the different alumina production methods, it is divided into sintering method, Bayer method and mixed method red mud. According to incomplete estimates, my country discharges more than 10 million tons of red mud every year, and the cumulative stockpiles of red mud are as high as tens of millions of tons, which are mainly stored by dam-building wet methods, and their utilization rate is only about 10%. With the development of industry and the reduction of the grade of aluminum ore, the discharge of red mud will increase, and the environmental problems caused by it have become a major restrictive factor for the sustainable development of enterprises.

[0003] Regardless of sintering red mud or Ba...
