Embodiment 1

[0016] Embodiment 1 A kind of stabilized soil for road base, comprising the following components in mass percentage: 75% of graded gravel produced in the construction waste crushing process, 2.5% of petroleum coke residue, 0.5% of white mud, 16% of fly ash, lime 2%, water 4%.

Embodiment 2

[0017] Embodiment 2 A kind of stabilized soil for road base, comprising the following components in mass percentage: 78% of graded gravel produced in the construction waste crushing process, 2.5% of petroleum coke residue, 0.5% of white mud, 12% of fly ash, lime 3%, water 4%.

[0018] Embodiment 1 A kind of stabilized soil for road base, comprising the following components in mass percentage: 72% of graded gravel produced in the construction waste crushing process, 5% of petroleum coke residue, 1% of white mud, 13% of fly ash, lime 4%, water 5%.

Embodiment 4

[0019] Embodiment 4 A kind of production method of stabilizing soil for road base, adopts the distribution ratio of each component of stabilizing soil for road base in Example 1, according to figure 1 Shown technological process, concrete steps are as follows:

[0020] 1. Crushing and grading adjustment: After sorting, crushing, and screening construction waste, gravel, sand, and sandy soil of different sizes are obtained and stored separately; through the grading adjustment machine, the amount of particles of various sizes is adjusted, so that The maximum particle size of construction waste recycled stone particles should not exceed 31.5mm, and the particle content of particles with a particle size less than 0.075mm should be close to 0;

[0021] 2. Grinding: Put the petroleum coke residue in the Raymond machine for grinding, so that its specific surface area reaches 380m 2 / kg.

[0022] 3. Weighing, measuring and mixing: Place the processed construction waste graded gravel...

Abstract

The invention relates to highway roadbase stabilized soil and particularly relates to highway roadbase stabilized soil produced by use of a product of building rubbish disposal and an industrially produced byproduct. The invention also relates to a production method of the stabilized soil. The highway roadbase stabilized soil comprises the following components by mass: 60-80% of graded gravel produced during crushing process of building rubbish, 2-5% of petroleum coke residue, 0.5-1% of white mud, 10-16% of fly ash and 2-5% of lime. The production method of the highway roadbase stabilized soil comprises the following steps: smashing, grading and adjusting, grinding, weighing, measuring, stirring and the like. Each detection index of the highway roadbase stabilized soil conforms to the stipulation of base materials in Technical Specifications for Construction of Highway Roadbases. The production method is simple in process flow, easy in operation and low in cost and is economic and environment-friendly; and special equipment is not needed.

Description

technical field [0001] The invention relates to a stabilized soil for road bases, in particular to a kind of stabilized soil for bases used in roads produced by utilizing the processed construction waste and by-products of industrial production, and also relates to a production method of the stabilized soil. Background technique [0002] As the pace of urban construction continues to accelerate, natural sand and gravel resources are increasingly exhausted, and comprehensive utilization of construction waste to produce recycled coarse and fine aggregates can completely replace natural sand and gravel. By using recycled products processed from construction waste, the disposal method of construction waste is effectively solved. At present, my country's construction waste is basically disposed of by landfill. 10 million tons of construction waste will occupy 10,000 mu of land and will pollute groundwater sources. The base stabilized soil used for highways now uses all natural m...
