Abstract
The invention discloses an improved roadbed filling material based on low liquid limit silt and a manufacturing method thereof, and belongs to the technical field of roadbed filling materials, wherein the improved roadbed filling materials comprise the following ingredients in the following proportion through being metered according to the total weight of the substrate filling materials: 2 to 4 percent of lime, 2 to 4 percent of fly ash and the balance silt. The lime and fly ash mixture is used for improving the low liquid limit silt; the permeability and the compaction performance of the low liquid limit silt can be reduced; the water stability of the roadbed filling soil is improved; in addition, the soil body intensity can be improved when the roadbed deformation is reduced; the improved silt can be used for highway roadbed filling materials; the building cost of a highway can be reduced.
Description
Technical field
The present invention relates to roadbed filling technical field, particularly relate to a kind of based on silt improvement roadbed embankment material and
Manufacture method.
Background technology
Silt, silt be distributed widely in the alluvial plain of China, fluvial-delta, coastal plain area, this kind of native one
As viscosity poor, disproportionately graded, liquid limit be worth little plasticity index low, intensity is low, California bearing ratio CBR (California Bearing
Ratio) it is difficult to reach engineering design requirements, is the poor road-making material of a kind of engineering properties, this low liquid limit silt soil sample
Grating is poor, and the soil body has higher compressibility and permeability, is used as the compacting of roadbed filling difficulty and compaction quality is difficult to ensure that, the soil body
Intensity can not meet the code requirement of roadbed filling, therefore cannot be directly used to filling roadbed, is especially not applied at a high speed
The High-Grade Highway Subgrade such as highway.In " Highway Roadbed Construction Technology specification ", not yet clear stipulaties uses silt, silt at present
Fill the provision of High-Grade Highway Subgrade.
Summary of the invention
It is an object of the invention to for the problem that presently, there are, it is provided that a kind of roadbed based on the improvement of low liquid limit silt is filled out
Building material and preparation method thereof, it can solve the problem that low liquid limit silt cannot be directly used to fill asking of High-Grade Highway Subgrade
Topic.
The purpose of the present invention is achieved through the following technical solutions:
The present invention provide a kind of based on low liquid limit silt improvement roadbed embankment material, described roadbed embankment material according to
The gross weight meter of roadbed embankment material, each composition and proportioning be: Calx 2%～4%, flyash 2%～4%, remaining is flour sand
Soil.
It is highly preferred that described roadbed embankment material according to the gross weight meter of roadbed embankment material, the proportioning of each composition is: stone
Ash 3%, flyash 3%, remaining is silt.
It is highly preferred that described Calx uses the Calx after clearing up.
It is highly preferred that the loss on ignition of described flyash is not more than 10%, specific surface area is more than 2500cm2/g, and 90% passes through
The sieve aperture of 0.3mm, 70% by the sieve aperture of 0.075mm.
It is highly preferred that the coarse fraction of described silt is less than 25%, liquid limit value is less than 50%.
The present invention also provides for the manufacture method of a kind of roadbed embankment material based on the improvement of low liquid limit silt, comprising:
Step S11, according to roadbed embankment material total amount needed for engineering and the road described in claim 1 to 5 any one
The proportioning of base filling material is got the raw materials ready；
Step S12, is mixed and stirred Calx and flyash as in optimum mix incorporation silt；
Step S13, adds water and is sufficiently stirred for；
Step S14, stands and sets time period, the silt roadbed embankment material after being improved.
By the technical scheme of the invention described above it can be seen that the present invention has the following technical effect that
The present invention can not only reduce the permeability of this low liquid limit silt, compressibility, improves the water stability of Roadbed Soil, and
And soil strength can be increased while reducing subgrade deformation, the silt after improvement may be used for express highway roadbed filling out
Material, can reduce expressway construction cost.
Accompanying drawing explanation
Fig. 1 is the flow process of the manufacture method of a kind of based on the improvement of low liquid limit silt the roadbed embankment material of the present invention
Figure.
Detailed description of the invention
In order to make those skilled in the art be more fully understood that the technical scheme of the application, below with reference to accompanying drawing to this
Bright it is described in further details.
The applicant carries out laboratory soil test to the silt of job site, analyzes its engineering mechanics property, this flour sand
Soil is low liquid limit silt, there is the shortcomings such as its permeability is big, compressibility is big, soil strength is inadequate, and the applicant is for low liquid
Limit these shortcomings of silt, use Calx and flyash to improve low liquid limit silt, and the silt after improvement can
For express highway roadbed filler.
The present invention provides a kind of roadbed embankment material based on the improvement of low liquid limit silt, and it is according to roadbed embankment material
Gross weight meter, the proportioning of each composition is: Calx 2%～4%, flyash 2%～4%, and remaining is silt.
Calx: require to meet the requirement of each index of more than three grades of ashes, use the Calx cleared up.
Flyash: loss on ignition is not more than 10%, specific surface area is more than 2500cm2/g, and 90% by the sieve aperture of 0.3mm,
70% by the sieve aperture of 0.075mm.
Low liquid limit silt: coarse fraction is less than 25%, liquid limit value is less than 50%.
Embodiment one:
According to the gross weight meter of roadbed embankment material, the proportioning of each composition is: Calx 2%, flyash 2%, and remaining is powder
Sand.
Embodiment two:
According to the gross weight meter of roadbed embankment material, the proportioning of each composition is: Calx 2%, flyash 4%, and remaining is powder
Sand.
Embodiment three:
According to the gross weight meter of roadbed embankment material, the proportioning of each composition is: Calx 4%, flyash 2%, and remaining is powder
Sand.
Embodiment four:
Calx 3%, flyash 3%, remaining is silt.
Embodiment five:
Calx 4%, flyash 4%, remaining is silt.
Above-described embodiment is sampled, is compressed test, CBR test, permeability test survey, determines that its engineering mechanics parameter is full
The requirement of foot " Highway Roadbed Construction Technology specification ".Result of the test is as shown in table 1:
Table 1
By above-mentioned table 1 it can be seen that match ratio be Calx 3%, flyash 3%, remaining be the detection of low liquid limit silt
The CBR value of soil sample is maximum, and performance is optimal, and this is also the optimum proportioning of the present invention.
The present invention also provides for a kind of manufacture method of roadbed embankment material based on the improvement of low liquid limit silt, it include as
Lower step:
Step S11, gets the raw materials ready according to roadbed embankment material total amount and proportioning needed for engineering.
Silt need to sieve, and granularity is 0.005mm～0.35mm, wherein more than the content < 50% of 0.075mm particle diameter.
Step S12, is mixed and stirred Calx and flyash as in optimum mix incorporation silt.
Step S13, adds water and is sufficiently stirred for, and amount of water is pressed the optimum moisture content of silt and calculated.
Step S14, stands and sets time period (as stood 30min), the silt roadbed embankment material after being improved.
Although the present invention is open as above with preferred embodiment, but embodiment does not limit the present invention.Without departing from this
In bright spirit and scope, any equivalence change done or retouching, also belong to the protection domain of the present invention.Therefore the present invention
The content that should be defined with claims hereof of protection domain as standard.
