Abstract
The invention relates to a highway subgrade material, in particular to a highway subgrade material which contains the coal slag and the fly ash and is mainly manufactured from residual coal slag and fly ash produced in the production process of thermal power plants and coal enterprises, and belongs to the technical field of highway building materials. The highway subgrade material is mainly manufactured from the residual coal slag and the fly ash produced in the production process of the thermal power plants and the coal enterprises by incorporating a small amount of lime, plaster, sand or soil through stirring, spreading and compacting. The subgrade material is easily obtained, can effectively use the leftovers of thermal power and coal enterprises, changes waste into valuables, conformsto the requirement of environmental protection, lowers the highway construction cost, and ensures the pavement quality.
Description
Technical field
The present invention relates to a kind of highway subgrade material, specifically relating to a kind of heat power plant and the remaining cinder of coal enterprise's production process, flyash of utilizing is main a kind of highway subgrade material that contains cinder, flyash of making, belongs to highway structure material technology field.
Background technology
At present, along with The development in society and economy, road construction is also in pick up speed, and the highway subgrade material therefor adopts rubble, concrete or pseudo-ginseng soil or cement, flyash, sandstone compound mostly, in building highway, adopt above-mentioned materials, the cost height, intensity is low, and returns slurry easily, be difficult to guarantee construction quality, cause the road surface promptly need study for a second time courses one has flunked, bring a very big difficult problem, do not have good terms of settlement so far to pavement maintenance once weight.
Summary of the invention
The objective of the invention is for overcoming above-mentioned the deficiencies in the prior art part, a kind of highway subgrade material that contains cinder, flyash is provided, this roadbed material utilizes heat power plant and the remaining cinder of coal enterprise's production process, flyash to be the master, mix a small amount of lime, gypsum, sand or soil through stir, pave, the material of compacting.This roadbed material is easily got, and can effectively utilize the tankage of thermoelectricity, coal enterprise, turns waste into wealth, and compliance with environmental protection requirements reduces the highway construction cost, guarantees pavement quality.
The present invention realizes with following technical scheme: a kind of highway subgrade material that contains cinder, flyash is characterized in that: this roadbed material comprises the following material of forming by weight: cinder 40-90 part flyash 20-60 part lime 15-20 part sand 15-30 part water 10-20 part.
Described roadbed material also can add a small amount of gypsum, or substitutes flyash with a small amount of soil.
The described preparation method who contains the highway subgrade material of cinder, flyash is characterized in that: cinder, flyash, lime, sand, water admixed in proportion stirred, pave evenly by paver after, the street roller compacting gets final product.
Advantage of the present invention is: this roadbed material is easily got, and can effectively utilize the tankage of thermoelectricity, coal enterprise, turns waste into wealth, and compliance with environmental protection requirements reduces the highway construction cost, guarantees pavement quality.
