Abstract

The invention provides a formula, a preparation method and application of a salt rock base mixture. The salt rock base mixture is prepared from salt rock aggregate, saturated brine, polyvinyl alcohol, calcium carbonate micro powder, an aluminate coupling agent, emulsion, lignin fiber, slaked lime, alkaline residues, furnace ash and slag micro powder. The formula is adopted to prepare the salt rock base mixture; the prepared salt rock base layer mixture is applied to construction of a salt rock base layer, so that various properties of the salt rock base layer can be remarkably improved, the stability of the base layer is improved; the constructed gravel seal salt rock base layer has a three-layer structure of a salt rock gravel layer, a bonding layer and a gravel layer, and the structure can ensure the strength of the salt rock base layer and can effectively relieve structural damage caused by the intrusion of surface water into the salt rock base layer. The base layer is high in strength, good in flexibility, high in salt expansion disease resistance and shear force bearing capacity and high in stability.

Description

technical field [0001] The invention belongs to the field of road materials, and relates to a salt rock base mixture, in particular to a salt rock base mixture, a preparation method and an application. Background technique [0002] Salt rock is a kind of soil with special properties existing in Xinjiang, Qinghai, Tibet and other regions of my country. It has the characteristics of good compactness, high strength, strong compaction and easy dissolution. Due to the lack of traditional road construction materials in the salt rock area, salt rock is tried to be used as the road construction material in the construction process of new or expanded roads, but the overall construction level is average, mainly because most roads in the salt rock area are based on salt crust Filling the salt rock subgrade without paving the pavement structure. Although the top surface of the subgrade has high strength, it is prone to serious rutting, looseness, potholes and other diseases when it enco...
