Abstract
The invention discloses a method for processing a precast cold laid asphaltic concrete material, which comprises the following steps of: (1) heating and mixing asphalt, graded broken stone and a mineral powder mixed material in a batching and mixing plant to form an asphaltic concrete mixed material; (2) adopting a mould to mould the asphaltic concrete mixed material in a thermal state into sheets which are convenient to splice and have the thickness of 2-9cm, and reducing to normal temperature; and (3) packaging, loading, and transporting the sheets at normal temperature to construction field, arranging and splicing the sheets in the field, heating, and rolling to achieve good density. The processing method makes more work such as mixing the asphaltic concrete material and primarily rolling and forming performed in a factory, and can achieve specialized and industrial production.
Description
Technical field:
The present invention relates to a kind of processing method of precast cold laid asphaltic concrete material.
Background technology:
Now, general asphalt concrete pavement construction operation all is 1, in the bituminous mixture mixing station pitch, rubble, breeze etc. is added thermal agitation 2, entrucking, and that insulation is transported to is on-the-spot 3, the paver scene paves fast 4, road roller is to material grinding compacting and the moulding of paving.
What mixing station now carried out is power choring production, is beneficial to the resettlement and the installation of mixing station equipment, so this construction technology is equivalent to the cast-in-place construction of cement concrete construction, is not easy to suitability for industrialized production.
Simultaneously because the bituminous mixture that dispatches from the factory does not roll through preparatory processing, so pave and the work that rolls is all carried out at the scene, high temperature loose asphalt compound is exposed in the aerobic environment for a long time, has quickened wearing out of pitch.
Moreover if asphalt concrete pavement adopts " pavements by transporting bituminous concrete at normal temperature construction " patented technology, the loose asphalt compound is inconvenient to pave.
Summary of the invention:
For overcoming the defective of prior art, the object of the present invention is to provide a kind of processing method of precompressed cold laid asphaltic concrete material, in the hope of on-the-spot high temperature attitude traditional in the asphalt concrete pavement construction method is paved, rolls once-forming, change the prefabrication preliminarily forming into, the final completion of on-the-spot reprocessing.
Technical solution problem of the present invention adopts following technical scheme:
The processing method of precast cold laid asphaltic concrete material, carry out as follows:
A, in mixing station with pitch, graded broken stone, mineral powder mixed material heating mix, mix forms the bituminous concrete mix; In the concrete operations, when pitch, graded broken stone, mineral powder mixed material proportioning are conveyed in the mix storehouse, the mix storehouse is vacuumized, so that be under the state of few oxygen/oxygen barrier, to carry out mix to reduce ageing of asphalt to compound.
B, employing mould are molded into the thick thin slice of 2～9CM of being convenient to assembly unit to hot described bituminous concrete mix, and adhere to geotextiles in the bottom surface of thin slice, reduce to normal temperature; In the concrete operations, can adhere to geotextiles in the bottom surface of thin slice, make its globality stronger, the bituminous concrete mix is to be molded into described thin slice under few oxygen/oxygen barrier state.
C, with described thin slice packing, the entrucking of normal temperature, be transported to the job site, put the combination of assembly unit thin slice at the scene, heating and rolling is closely knit.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, adopts processing method of the present invention, the mix of asphalt concrete material and the processing of preliminary roller-compaction or the like more work all has been placed in the factory carries out, can accomplish specialization, industrialization production.
2, owing to be more specialized production, each road working procedure can drop into more large-scale equipment, can accomplish large-scale production, the amortization product cost.
3, owing to specialized more production, more main equipment production, the input and the control of environmental protection and energy saving be can conveniently carry out, better environmental protection and energy-saving effect reached, for example the control of flue gas, dust.
4, owing to be professionally more competent, more concentrated more suitability for industrialized production, controllable quality is more prone to, for example pitch quick aging under high temperature and aerobic conditions, in order to keep the pitch activity, can be when plant mix, high temperature but anaerobic, it is isolated with oxygen tentatively to roll the back, heat again and when rolling,, help anti-oxidant though the interior oxygen of the high closely knit bituminous concrete of temperature is less.
The specific embodiment:
Embodiment: the processing method of the precompressed cold laid asphaltic concrete material of present embodiment, carry out as follows:
A, at first routinely graded broken stone, mineral powder mixed material (add by weight percentage 10%～100% ferrite or other absorbing materials) and pitch mix under the oxygen barrier state are formed the bituminous concrete mix in described breeze in mixing station; Because equipment does not need frequent resettlement, according to than general pitch mixing station higher require configuration device, on equipment, mix dedusting, waste gas are more deepened design, help environmental protection like this; Simultaneously for alleviating ageing of asphalt, at hot stage, the oxygen in the air-isolation, favourable to the durability that improves bituminous concrete like this.
B, employing mould, hot described bituminous concrete mix is molded into the thick thin slice of 2～9CM of being convenient to assembly unit under the oxygen barrier state, shape is generally square or other can make things convenient for the shape of assembly unit, can be with reference to prefabricated side walk slab's design, in order to improve the globality of asphalt concrete material, can be on chemical fabric with the asphalt concrete material compression molding, utilize chemical fabric to strengthen the thin slice globality, after the moulding, bottom surface at thin slice adheres to geotextiles, reduce to normal temperature, isolate oxygen, reduce the ageing of asphalt degree in the compression molding stage.
C, with described thin slice packing, the entrucking of normal temperature, be transported to the job site, put the combination of assembly unit thin slice at the scene, heating and rolling is closely knit.
Claims (3)
1. the processing method of precast cold laid asphaltic concrete material is characterized in that carrying out as follows:
A, in mixing station with pitch, graded broken stone, mineral powder mixed material heating mix, mix forms the bituminous concrete mix;
B, employing mould are molded into the thick thin slice of 2～9CM of being convenient to assembly unit to hot described bituminous concrete mix, reduce to normal temperature;
C, with described thin slice packing, the entrucking of normal temperature, be transported to the job site, put the combination of assembly unit thin slice at the scene, heating and rolling is closely knit.
2. the processing method of precast cold laid asphaltic concrete material according to claim 1 is characterized in that in steps A, and described pitch, graded broken stone, mineral powder mixed material are to carry out mix to reduce ageing of asphalt under the state of oxygen barrier.
