Description
Technical field
The present invention relates to road asphalt and processing technique field, the preparation side of a kind of asphalt-regenerating concrete
Method.
Background technology
At the express highway pavement that China is built, 90% is above semi-rigid asphalt pavement, the master of bituminous paving
Wanting composition is bituminous concrete, and its reason being widely used is: 1, planarization is good, drives a vehicle the most comfortable, and noise is low；2, drip
It is big that blue or green semi-rigid type base has intensity, good stability and the feature such as rigidity is big；3, cement road belongs to rigid ground, it is necessary to connect
Seam, difficulty of construction is bigger, expands with heat and contract with cold and the most easily produces cleavage block；4, fast with bitumen construction, maintenance is also convenient for.
Owing to existing bituminous highway gets more and more, along with the increase of use frequency, the loss percentage of bituminous paving also increases,
Being typically to dig up impaired section again to pour bituminous concrete, this mode needs again to pour new bituminous concrete, dimension
The cost protected is bigger, operates the most complicated；If Applied of Asphalt Pavement Recycle Technique can be used for the maintenance of highway, not only may be used
With by original ground surface material regeneration, protect environment, reduce construction costs, but also original road surface material can be corrected
The defect of material, transforms the structure on original road surface, extends the life-span on road surface, but existing Applied of Asphalt Pavement Recycle Technique exists process again
Miscellaneous, relatively costly, the defect such as amount of dust is big and environmental-protecting performance is poor, this is also not have commonly used main cause.In consideration of it, it is anxious
Need a kind of new asphalt-regenerating concrete technology, solve the problems referred to above.
Summary of the invention
For above-mentioned technical problem, the present invention provides the preparation method of a kind of asphalt-regenerating concrete, it is possible in low cost
On the premise of realize quickly preparing asphalt-regenerating concrete, and have that the waste asphalt material response rate is high, process easy, preparation side
The advantages such as method is simple, good dedusting effect and good environmental protection.
The technical problem to be solved realizes by the following technical solutions:
The preparation method of a kind of asphalt-regenerating concrete, comprises the following steps:
Step (1): will be put on grating belt from road-surface milling or the waste asphalt material that digs out；
Step (2): the waste asphalt material in step (1) is sent to reworked material according to certain yield and is dried rolling by grating belt
In Tong, obtain reworked material；
Step (3): while step (2) is run, the hot blast that burner produces after burning in combustion chamber is with reworked material
High-end to low end motion from reworked material drying drum together, reworked material is uniformly heated to uniform temperature by hot blast, obtains hot old material
And Colophonium；
Step (4): the old material of heat obtained from step (3) is introduced into temporary bucket, hot old material is under program by temporarily
Deposit the entrance weighing hopper of the pneumatic discharging door on bucket to weigh；
Step (5): the old material of heat after weighing in the Colophonium obtained in step (3) and step (4) passes through chute in program control
Periodical processed joins in a mixing bowl, stirs with building stones, new Colophonium, powder, obtains asphalt-regenerating concrete.
As a preferred technical solution of the present invention, the Colophonium obtained in step (3) not with burner in combustion chamber
Direct flame contact, thus be effectively increased the response rate of waste asphalt material Colophonium at end, reduce cost.
As a preferred technical solution of the present invention, the flue dust one that the Colophonium obtained in step (3) produces after being heated
Dividing in being sent into combustion chamber by air-introduced machine and flash back, another part is admitted to virgin material drying drum and carries out second-time burning, enters after burning
Dust pelletizing system carries out dedusting, improves the dust removal efficiency of dust, protect environment, also further increase waste asphalt material simultaneously
The response rate of whole Colophonium.
The invention has the beneficial effects as follows: the preparation method of the present invention is compared to existing technology, it is possible on the premise of low cost
Realize quickly preparing asphalt-regenerating concrete, and take full advantage of waste asphalt material, decrease waste asphalt material burned
Loss in journey, eliminates the dust of generation timely, protects environment, solves what existing Applied of Asphalt Pavement Recycle Technique existed
The difficult problems such as process is complicated, relatively costly, amount of dust is big and environmental-protecting performance is poor, and have that the waste asphalt material response rate is high, process letter
The advantages such as just, preparation method is simple, good dedusting effect and good environmental protection.
Detailed description of the invention
In order to make technological means that the present invention realizes and creation characteristic be easy to understand, below the present invention is explained further
State.
The preparation method of a kind of asphalt-regenerating concrete, comprises the following steps:
Step (1): will be put on grating belt from road-surface milling or the waste asphalt material that digs out；
Step (2): the waste asphalt material in step (1) is sent to reworked material according to certain yield and is dried rolling by grating belt
In Tong, obtain reworked material；
Step (3): while step (2) is run, the hot blast that burner produces after burning in combustion chamber is with reworked material
High-end to low end motion from reworked material drying drum together, reworked material is uniformly heated to uniform temperature by hot blast, obtains hot old material
And Colophonium；
Step (4): the old material of heat obtained from step (3) is introduced into temporary bucket, hot old material is under program by temporarily
Deposit the entrance weighing hopper of the pneumatic discharging door on bucket to weigh；
Step (5): the old material of heat after weighing in the Colophonium obtained in step (3) and step (4) passes through chute in program control
Periodical processed joins in a mixing bowl, stirs with building stones, new Colophonium, powder, obtains asphalt-regenerating concrete.
The Colophonium obtained in step (3) not with burner direct flame contact in combustion chamber, thus effectively increase
The response rate of waste asphalt material Colophonium at end, reduces cost.
