Embodiment three
Consumer waste incineration slag is filled suitable in highway road surface integrated application in lime fly ash comprehensive stability material
The incineration slag of amount, consumer waste incineration slag is mutually mixed thoroughly with gathering materials, then makes itself and the mutual mix of inorganic stabilizers material, is used
In subgrade and pavement.
The primary raw material of described lime fly ash comprehensive stability material includes lime, flyash, consumer waste incineration slag
With gather materials.
The consumption (mass fraction) of each raw material is：
According to JTG/T F20-2015《Highway road surface construction technology detailed rules and regulations》Middle relevant regulations, lime fly ash is integrated
The ratio recommendation of lime and flyash is 1 in stabilizing material:2~1:4, lime fly ash total amount is with the ratio recommendation gathered materials
15:85~20:80.Under appropriate lime and flyash ratio, the incineration slag of different addition quantity is added in gathering materials, it is met
Aggregate grading requirement, aggregate particle compositing range is as shown in the table：
The macadam gradating particle compositing range of table 1
In order to substitute rubble with incineration slag to greatest extent, and matched somebody with somebody using specification intermediate value as target level, by adding into incineration slag
Plus the method for rubble adjusts the particle diameter compositing range of mixture particle.The particle composition of incineration slag rubble after adjustment is being met
While specification the volume of incineration slag in compound can be made to be up to more than 75%.Determine lime fly ash incineration slag rubble steady
Determine material maximum dry density and optimum moisture content, carry out lime fly ash incineration slag rubble stabilizing material and lime fly ash rubble
Stabilizing material unconfined compression strength test, with JTG/T F20-2015《Highway road surface construction technology detailed rules and regulations》Middle correlation will
Ask and compare, its feasibility of overall merit.Relevant criterion is required shown in table 2.
The compressive strength standard of the lime fly ash macadam-aggregate mix of table 2
| Aspect | Two grades and two grades to get down the highway | Highway and Class I highway |
| Basic unit (MPa) | 0.6~0.8 | 0.8~1.1 |
| Underlayment (MPa) | ≥0.5 | ≥0.6 |
The lime fly ash mix-design that gathers materials is as shown in the table：
The lime fly ash incineration slag rubble mix-design of table 3
Its maximum dry density and optimum moisture content are determined by compaction test, as a result as shown in table 4：
The incineration slag compaction test results of table 4
| Project | A | B | C | D | E | F | G | H | I |
| Optimum moisture content (%) | 10.8 | 10.6 | 10.4 | 10.5 | 10.3 | 10.5 | 10.4 | 10.2 | 9.9 |
| Maximum dry density (g/cm3) | 1.90 | 1.97 | 1.99 | 1.93 | 1.96 | 2.02 | 1.91 | 1.99 | 2.03 |
It is as shown in table 5 that common lime fine coal ash broken stones stabilizing material hits real result：
The compaction test results of table 4
| Project | A | B | C | D | E | F | G | H | I |
| Optimum moisture content (%) | 10.1 | 9.5 | 8.9 | 10.0 | 8.8 | 9.1 | 9.2 | 9.5 | 8.6 |
| Maximum dry density (g/cm3) | 2.0 | 2.06 | 2.10 | 2.02 | 2.07 | 2.12 | 2.03 | 2.07 | 2.13 |
Compare both unconfined compressive strength results as shown in table 6：
The unconfined compressive strength result of table 6
From the results, it was seen that after incorporation incineration slag, lime fly ash rubble stabilizing material maximum dry density reduces,
Optimum moisture content rises, and unconfined compressive strength also can accordingly reduce about 10%.This is due to incineration slag porosity greatly and pressed
Broken value is big, admittedly causing itself stress performance poor, but under large dosage use, can save substantial amounts of natural rubble and gather materials,
And loss of strength is smaller, it is set still to be able to meet designing quality use requirement.
It should be noted last that：Above example is only used to illustrative and not limiting technical scheme, although ginseng
The present invention is described in detail according to above-described embodiment, it will be apparent to an ordinarily skilled person in the art that：Still can be to this
Invention is modified or equivalent substitution, any modification or partial replacement without departing from the spirit and scope of the present invention, and its is equal
It should cover among scope of the presently claimed invention.
