The price depends on your city, location and construction environment. Examples are as follows:
1. In many places, the unit price of buying land alone reaches tens of yuan /m3, some have seen 45 yuan /m3, and some have heard that it reaches 60-70 yuan.
2. Look at the distance you transport. If it is close, the earthwork must be relatively cheap. If it is far away, it will be different.
3. Look at the traffic conditions of roads and construction sites, and see if the vehicles are easy to walk.
Look at your total amount, the more, the cheaper.
Lime is worthless, and 5% lime is basically ignored. Consider the labor and mechanical costs of mixing, and then mainly look at the unit price of soil.

The parent rock of calcareous soil is mainly limestone mixed with calcite and aragonite, followed by dolomite mixed with dolomite, which is different from other transitional carbonate soils in color. There are four common types: red, yellow, brown and black. This is a piece of brown calcareous soil taken from Guiyang area. Is the soil thick? 50? Centimeter. The topsoil is grayish brown, gradually changing from dark reddish brown to light reddish brown, and the bottom layer is light purple gray limestone parent layer. This soil is widely distributed in Guangxi, Guizhou, Yunnan and other provinces. ?
It belongs to calcareous soil. Application: engineering application? Lime soil, mainly used in road engineering, is also called lime stabilized soil, that is, it is composed of a certain amount of lime (generally 4%~ 12% of the mass of lime) and water. This stabilized soil has good plate-like properties, but its water stability, frost resistance and early strength are lower than those of other inorganic binders. Lime soil also has one of the most obvious shortcomings: the characteristics of dry shrinkage and temperature shrinkage are very obvious, which easily leads to cracking of pavement base. Therefore, at this stage, lime soil has been forbidden to be used at the base of high-grade roads, such as expressway, first-class highways, second-class highways, urban expressways and trunk highways. But it can be used for subbase of roads at all levels. Its applicability is not as good as cement stabilized soil.
The difference between lime soil and lime soil
When the original soil is mixed with ashes, it is removed. Usually refers to the method of treating soil at the grass-roots level. According to the design requirements, after the subgrade base is dug, the designed amount of ash shall be sprinkled, mixed, rolled and maintained. This is a kind of calcareous soil. The parent rock of calcareous soil is mainly limestone mixed with calcite and aragonite, followed by dolomite mixed with dolomite, which is different from other transitional carbonate soils in color. There are four common types: red, yellow, brown and black. This is a piece of brown calcareous soil taken from Guiyang area. Is the soil thick? 50? Centimeter. The topsoil is grayish brown, gradually changing from dark reddish brown to light reddish brown, and the bottom layer is light purple gray limestone parent layer. This soil is widely distributed in Guangxi, Guizhou, Yunnan and other provinces. ?
It belongs to calcareous soil. Lime (rock) soil is a kind of soil developed on weathered carbonate rocks in tropical and subtropical regions. Most of them are clay, with high soil exchange capacity and base saturation, and clear transition between soil and bedrock surface. Lime (rock) soil can be divided into four subcategories, all of which are distributed in this area. The subclasses of red calcareous soil are mostly developed in the ancient weathering crust of thick limestone, which is the calcareous (rock) soil with the strongest weathering and leaching and the deepest decalcification. The soil has no lime reaction and the pH value is neutral. Black calcareous soil is a kind of A-R soil scattered between rock cracks and peaks in karst areas. The black humus layer is 20-40 cm thick, with 5-7% organic matter content, low decalcification degree, and the soil reacts with lime and is weakly alkaline. The subclass of brown calcareous soil is between the first two, and there is no lime reaction or weak lime reaction; The subclass of yellow calcareous soil is distributed in mountainous areas above 800 meters above sea level, and is often interlaced with yellow brown soil or yellow soil. Soil has yellowing characteristics and neutral reaction.
The above is about the price of limestone and some differences between lime soil and lime soil. Lime soil is deeply influenced by parent rock, because it is in subtropical warm climate for a long time, so it is very easy to corrode and weather. We should also pay attention to its characteristics when using it, so as to seek advantages and avoid disadvantages. I hope the above contents can bring some help and reference to everyone. At present, lime soil has been forbidden to be used in the base of high-grade roads, which is also because its practicability is not as stable as cement soil.
