specific Embodiment approach 1

[0017] Specific implementation mode one: the road grass-roots compound material that this embodiment takes saline-alkali soil as raw material consists of 50-97 parts by weight of saline-alkali soil, 3-10 parts of cement, 8-10 parts of water, 0.01-0.2 parts It is prepared from a soil stabilizer and 0.01-0.1 parts of a surface alkali inhibitor.

[0018] This embodiment has the following beneficial effects:

[0019] In this embodiment, saline-alkali soil is used to make the road base mixture. On the one hand, saline-alkali soil can be utilized as a resource, and on the other hand, precious resources such as sand and gravel aggregates used in traditional road construction can be saved, thereby saving a lot of investment. In this embodiment, the soil curing agent is used to process the saline-alkali soil as a resource and produce the road base mixture, and the compressive strength of the obtained road base is not less than 20Mpa. Using oxalic acid or tartaric acid to treat the roa...

Abstract

The invention discloses a road base mixture taking saline-alkali soil as a raw material and a preparation method of a road base, and relates to a road base mixture and a preparation method of a road base. The method aims at solving the problem that existing saline-alkali soil treatment is high in difficulty. The road base mixture is prepared from saline-alkali soil, cement, water, a soil curing agent and a surface alkali inhibitor in parts by weight. The method comprises the following steps: weighing the raw materials in parts by weight; and after mixing, performing paving and compacting to form a road base, and spraying a surface alkali inhibitor on the surface of the road base. The road base mixture is prepared from saline-alkali soil, so that the saline-alkali soil can be recycled, resources such as sandstone aggregate used for traditional road construction are saved, and the compressive strength of the obtained road base is not lower than 20Mpa. The method is suitable for preparingthe road base.

Description

technical field [0001] The invention relates to a road base compound and a preparation method of the road base. Background technique [0002] Saline-alkali soil is formed by soil salinization. Soil salinization is a kind of soil disaster caused by natural or human factors, and it is a worldwide resource problem and ecological problem. In the process of soil salinization, soluble salts accumulate on the soil surface, while in soil alkalization, the exchangeable sodium in the soil increases and sodiumization occurs; the two are related to each other, and their development is a complex dynamic process. It is formed by the coupling of soil parent material, climate, hydrology, vegetation, human activities and many other factors. Soil salinization can directly cause salt stress to vegetation, reduce the availability of soil nutrients, and further deteriorate the soil structure, which not only causes the destruction of land resources, causes the loss of agricultural production, bu...
