Particle.
Preferably, preliminary smashed broken concrete is delivered at screening plant by transmission belt, is filled using screening
It sets and screening and filtering is carried out to preliminary smashed broken concrete, screening plant filters the concrete particle for meeting Particle size requirements
Out, conveyer belt then can be used concrete particle is delivered at storing and concrete particle is packaged, in order to subsequent paving
It is used when road.
In view of the broken concrete that Particle size requirements are not met after tentatively crushing secondary use the problem of, in above-mentioned implementation
It further include step S15 and step after carrying out screening and filtering to preliminary smashed broken concrete on the basis of example
S16:
S15: the broken concrete for not meeting Particle size requirements is crushed again.
Preferably, broken concrete is crushed again using the second pulverizer, to obtain required concrete particle.Choosing
When selecting the second pulverizer, the size of the size and concrete particle that do not meet the broken concrete of Particle size requirements need to be comprehensively considered.
S16: screening and filtering is carried out to smashed broken concrete again, obtains the concrete for meeting Particle size requirements
Grain；S15 is continued to execute to the broken concrete for not meeting Particle size requirements.
Preferably, screening and filtering, screening plant are carried out to smashed broken concrete again using above-mentioned screening plant
The concrete particle for meeting Particle size requirements is filtered out, conveyer belt then can be used, concrete particle is delivered at storing to mixed
Solidifying soil particle is packaged, in order to use when subsequent pave the way.
It should be noted that when after separating twice broken concrete do not meet Particle size requirements still after screening and filtering
Broken concrete, then the broken concrete for not meeting Particle size requirements is continued to crush three times, four crushing etc., so be followed
Ring crushing, screening and filtering, until all broken concretes meet Particle size requirements, to make full use of resource.
In order to make tentatively to crush there is preferable crushing effect to try on the basis of above-described embodiment by concrete
Further include step S17 before block tentatively crush:
Step S17: control single enters the quantity of the concrete test block of pulverizer when tentatively crushing.
Preferably, concrete test block made from step S12 is conveyed as haul machinery and is put into first disintegrator
Control is adjusted to the test block quantity for entering first disintegrator by regulating tank in loading hopper, when so as to tentatively crush every time,
With appropriate number of concrete test block, to guarantee the optimum efficiency crushed.
In order to guarantee the accuracy of screening and filtering, on the basis of above-described embodiment, to preliminary smashed concrete
Fragment carries out the process of screening and filtering, including step S18:
Step S18: screening and filtering is carried out to preliminary smashed broken concrete using multistorey strainer mesh system.
Multistorey strainer mesh system can guarantee screening precision, and the concrete particle filtered out is made to be all satisfied Particle size requirements.
It should be noted that during the entire process of concrete particle preparation, it is preferable that by dust collection equipment to generation
Fugitive dust is dusted.That is, carrying out Multipoint synchronous dedusting in multiple positions such as crushing, screening and filtering.

Step S26: pitch gluing layer is sprayed on the existing road surface come into operation.
It is understood that when needing in the existing road surfacing concrete particle to have come into operation, due to existing road
The asphalt concrete pavement in face has been compacted, and in order to enable concrete particle effectively to bind with existing road surface, therefore, it is necessary to head
One layer of pitch gluing layer is first sprayed on existing road surface.
The pitch gluing layer can be plain asphalt adhesive layer, or modified pitch gluing layer, modified pitch cohere
The bond performance of layer is preferable.When construction, bond performance and cost etc. can be comprehensively considered because being usually specifically chosen.
It should be noted that the present invention is not specifically limited the thickness of pitch gluing layer, when Specific construction, can according to
The smooth roughness on construction road road surface, to spray the pitch gluing layer of different-thickness.
Step S27: by concrete particle spreading on pitch gluing layer.
Step S28: concrete particle is pressed into pitch gluing layer.
It should be noted that when concrete particle is pressed into pitch gluing layer, in order to avoid to original road surface and coagulation
Soil particle damages, and only by way of compacting, concrete particle is pressed into pitch gluing layer, that is, in compacting coagulation
When soil particle, not starting vibration.
Preferably, when compacting, using the road roller with rubber tyre.
In order to make pitch gluing layer uniform ground, on the basis of above-described embodiment, on the existing road come into operation
Further include step S29 before the process for spraying pitch gluing layer on face:
Step S29: cleaning and/or partial trim are carried out to existing road surface.
Preferably, after the completion of construction, by road-cleaning vehicle to the extra concrete particle being deposited on road surface into
Row, which cleans, to be collected, to recycle.
