It is (public can be divided into extraordinarily thick formula (nominal maximum particle diameter is greater than 37.5mm), coarse grain formula by the size of nominal maximum particle diameter for graded mixture
Claim maximum particle diameter 26.5mm or 31.5mm), middle grain formula (nominal maximum particle diameter 16mm or 19mm), particulate formula (nominal maximum particle diameter
9.5mm or 13.2mm), sand grains formula (nominal maximum particle diameter be less than 9.5mm) asphalt, be divided into hot asphalt by manufacturing process
Mixture, cold-mix asphalt mixture, reclaimed asphalt mixture etc..
Most common asphalt has two classes in engineering: one is bituminous concrete mixture, is by proper proportion
The mineral aggregate for meeting specified grading of coarse aggregate, fine aggregate and filler composition, remaining voidage after mixing and stirring, being compacted with asphalt binder
Mixture less than 10%, abbreviation bituminous concrete；It is the coarse aggregate, thin by proper proportion the second is bituminous concrete moxture
Gather materials and filler (or not filled) and pitch mix and stir, be compacted after mixture of the residue voidage 10% or more, abbreviation pitch
Macadam-aggregate mix.It is overhauled currently, Chinese Highway generally faces, a large amount of old pavements will generate a large amount of rubbles and drip after being cleaned
How green waste material rejoins these rubbles and asphalt waste in the highway newly built, and realization recycles, and is the new period

9. a kind of cold stirring means of construction of the highway mobile regenerated asphalt mixture, step include:
S1, aggregate screening: the parallelogram mechanism of rotation fixed railing glazing bar (501) end, it will be on fixed railing glazing bar (501)
Counter weight strip (503) is rotated to horizontal position, makes ring set (504) and through-hole (202) co-axially align corresponding on screening plant (2),
Then movable grid item (502) is inserted into corresponding through-hole (202) and ring set (504), makes movable grid item (502) and fixed railing
Glazing bar (501) collectively constitutes more intensive sieve (5) structure, sieves to aggregate；
S2, aggregate be broken and conveying: the aggregate passed through from sieve (5) the roller (203) that is broken further pulverizes, and forms aggregate
Particle；Particles of aggregates is transported on the second conveyer belt (402) using guide plate (6), so by the second conveyer belt (402) send to
In the feeding inlet of agitating device (3)；
S3, aggregate heating, drying: starting compressor circulates refrigerant according to operation of air conditioner principle in pipeline,
Condenser heat release around heating part (302) carries out heating, drying to the particles of aggregates in shell (301), with shell
(301) particles of aggregates is stirred, is raised by rotation, L-type lifting blade (3021), so that aggregate is sufficiently heated and dry；L-type lifting
Plate (3021) is obliquely installed, to be pushed ahead aggregate using its inclined posture；
S4, etc. material: the discharge port of shell (301) is lifted using hydraulic cylinder so that aggregate continue in heating part (302) flowing and
It does not push ahead, reworked material is waited to enter from the feeding inlet of regeneration ring (303)；
S5, reworked material screening: the extraction from through-hole (202) by movable grid item (502) leaves fixed railing glazing bar (501) formation
Then the sieve (5) of wide arc gap is sieved reworked material using the sieve of wide arc gap (5), adapt to regenerated particles generally compared with
Big construction characteristic；
S6, reworked material be broken and conveying: evaporator absorbs heat around screening plant (2), by screening plant (2) and its interior
Reworked material temperature reduces, and reduces pitch and glues stickiness, improves cold crushing effect；After the activity grid item (502) is extracted out, counter weight strip
(503) it naturally droops, parallelogram mechanism resets, and drives galianconism push rod (601) to rotate using long-armed push rod (505), will lead
It is oriented to the other side to plate (6), the reworked material after being crushed is defeated via first by guide plate (6) guiding first conveyer belt (401)
Band (401) is sent to be promoted at the feeding inlet of regeneration ring (303), into regeneration ring (303)；
S7, reworked material are secondary to be pulverized: reworked material enters after regeneration ring (303), and the strip reworked material not being broken is in blend stop
(305) enter in shell (301) straight down along its length under elicitation effect, abrasive material block (3012) is by the reworked material of accumulation
It washes open, be pushed into shell (301), and further crush；
S8, mixing: by hydraulic cylinder pressure relief, shell (301) resets, and aggregate and reworked material start to mix at middle part, hot bone
Material generates heat radiation to reworked material, and reworked material is heated, and restores cohesive structure, to be sticked to aggregate table for remaining pitch is even
Face forms the aggregate heap for being stained with pitch, spare.
10. a kind of cold stirring means of construction of the highway mobile regenerated asphalt mixture according to claim 9, feature
It is: is connected with the pipeline for heating part (302) for steam in the shell (301)；Vibration is installed outside the screening plant (2)
Dynamic motor；The aggregate enters after mixing part (304), is further raised to the groove body (3041) of protrusion inside shell (301)
It rises and stirring, the interior powder being arranged of groove body (3041) infiltrates into groove body (3041) by the powder hole (3042) on groove body (3041)
On surface, the aggregate for being stained with pitch is avoided to be sticky on groove body (3041).
