Abstract
The invention discloses a modified asphalt which comprises the following components by weight: 100 parts of asphalt and 4-6 parts of fly ash fiber cotton balls, wherein the fly ash fiber cotton balls take the fly ash as the main raw materials. After the raw material formed by the auxiliary materials including dolomite and slag is melted, the melted raw material is guided into a centrifugal machine and stretched to form fiber, a binding agent and a dustproof oil are sprayed onto the surface of the fiber at the same time, the fiber is blown into a cotton collecting machine to form a primary cotton felt, and the primary cotton felt is fed into a granulating machine and cut to obtain the modified asphalt. The performance of the asphalt is improved effectively, the modified asphalt is suitable for laying the road surface and has long service life, the subsequent maintenance cost is reduced due to the adoption of the modified asphalt, the waste resources are reused because the fly ash is used as the raw material of the fiber cotton balls, and the problems on resource scarcity and environmental protection are solved effectively.
Description
Technical field
The present invention relates to a kind of modifying asphalt.
Background technology
Bituminous pavement is generally by pitch and components of mixture.The use on oxidation, weather condition and the road surface of bituminous cement between its usage period particularly uses through heavy load, caused the road surface in time past and degenerate.But the wax content of pitch is higher, and the road surface of causing asphalt paving is easily softening when high temperature, produce pile-up, permeable, form the phenomenons such as reflection crack, surface deformation, a large amount of maintenance of surface expenses is had to drop in the havoc road surface therefore.Proposed multiplely to pitch method of modifying in addition in the prior art, but the properties-correcting agent kind of using is more, and cost is higher.
Summary of the invention
The object of the present invention is to provide the modifying asphalt of the high and long service life of a kind of reliability.
For achieving the above object, the present invention has adopted following technical scheme:
A kind of modifying asphalt is made of by weight following component: 100 parts of pitches, coal ash fiber cotton-wool 4-6 part.
Preferably; described coal ash fiber cotton-wool will be take flyash as main raw material; after rhombspar, slag are the raw material fusing of auxiliary material composition; import drawing-off formation fiber in the whizzer; simultaneously spray into binding agent and dust laying oil at fiber surface; and fiber blowed form just cotton felt to the cotton collecting machine, first cotton felt is sent into obtained after tablets press cuts subsequently.
Preferably, comprise the flyash of 60wt%, the rhombspar of 20wt% and the slag of 20wt% in the described raw material, described slag preferably adopts iron smelting slag.
The coal ash fiber cotton-wool is blown into stirrer by air-blast system stirs with pitch, behind the stirrer mix, namely form modifying asphalt, then add and directly to use at highway after handstone stirs.
Compared with prior art, beneficial effect of the present invention is: can effectively improve asphalt performance, be fit to the laying road road surface, shelf life is long, has reduced follow-up maintenance cost; And use flyash to be the fiber cotton-wool of raw material, and realized that waste resource utilizes again, efficiently solve the routed weary and environmental issue of resource.
Embodiment
Below in conjunction with specific embodiment component of the present invention is described further.
100 parts of embodiment 1 pitches, 5 parts of coal ash fiber cotton-wools; Take the iron smelting slag of the rhombspar of the flyash of 60wt%, 20wt% and 20wt% after the raw material fusing, import drawing-off formation fiber in the whizzer, simultaneously spray into binding agent and dust laying oil at fiber surface, and fiber blowed form just cotton felt to the cotton collecting machine, obtain the coal ash fiber cotton-wool after subsequently first cotton felt being sent into the tablets press cutting, and the coal ash fiber cotton-wool is blown in the stirrer that pitch is housed by air-blast system stirs with pitch in the stirred pot, just can obtain modifying asphalt after stirring; The rear directly practicality on highway that stirs of the modifying asphalt that then will obtain and an amount of handstone.
Below only be concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the rights protection scope of the present invention.
Claims (3)
1. a modifying asphalt is characterized in that, is comprised of by weight following component: 100 parts of pitches, coal ash fiber cotton-wool 4-6 part.
2. modifying asphalt according to claim 1; it is characterized in that; described coal ash fiber cotton-wool will be take flyash as main raw material; after rhombspar, slag are the raw material fusing of auxiliary material composition; import drawing-off formation fiber in the whizzer; simultaneously spray into binding agent and dust laying oil at fiber surface, and fiber blowed to cotton collecting machine form just cotton felt, first cotton felt is sent into obtained after tablets press cuts subsequently.
3. modifying asphalt according to claim 2 is characterized in that, comprises the flyash of 60wt%, the rhombspar of 20wt% and the slag of 20wt% in the described raw material, and described slag preferably adopts iron smelting slag.
