Description
Technical field
The present invention relates to a kind of preparation equipment of bituminous mixture, relate in particular to a kind of bituminous mixture mixing device.
Background technology
In recent years, along with the development of pavement material, increasing airport adopts bituminous material to build face, pitch road face in use, vital tasks such as bearing takeoff and landing, slide and parking is the basic platform that the airport function is able to give full play to.But because effect repeatedly such as load and environmental factor, road face structure in use also can be damaged gradually.Like diseases such as loose, crack, rut, hole, hole, depressions.The service performance of the face that just influences that these diseases have, as gather materials polishing, bellding etc.; But some disease then directly constitutes a threat to the flight safety of aircraft, as loose etc.The impact force of takeoff and landing makes the destruction of airfield pavement functional performance further aggravate.For ensureing the safe handling of airfield pavement, airdrome control maintenance department must take a series of measure and method to solve the repairing problem of airfield pavement.
At present, the patching material that airfield pavement is commonly used is colod-application bituminous mixture, and this compound applicability is strong, just has certain sponginess and caking property under the normal temperature, and construction does not receive temperature, season limit.Can give full play to easy construction, the fast advantage of open to traffic.But, since with the weak caking property of former road face, reach i.e. processing once more about 2 months usually in its final repairing life-span following of constantly washing away of traffic load and rainwater.This is a kind of acute repairing measure, can solve the provisional pit repairing that influences safety, but as daily use completely, on the high side comparatively speaking.
The advantage that hot-mix asphalt mixture has that repairing quality is good, durability is high, the road face after repairing can bear heavily loaded traffic.The method of producing the hot asphalt blended stock at present has three kinds: first kind is to mix and stir the field at bituminous mixture to produce the finished product compound with lorry mounted mixer, transports to the maintenance scene again; Second kind is to mix and stir the pitch blended stock in on-the-spot pot heating of maintenance; The third is to produce finished product pitch blended stock at on-the-spot small movable lorry mounted mixer or the combined maintenance truck of using of maintenance.
First method can guarantee the quality of bituminous mixture conscientiously, but it is too big to mix and stir once the amount of mixing and stirring of field, considerably beyond demand, causes cost of production higher, and is not suitable for remote maintenance work; Second method environment pollution and labour intensity are bigger, and the grating of bituminous mixture and bitumen aggregate ratio are difficult for strict control, influence construction quality; The third method is practical, but the miniature movable type lorry mounted mixer lacks approved product at present, and many is that maintenance department develops voluntarily, and functional performance and reliability are very poor.Using combined maintenance truck to repair the hole groove is a kind of maintaining process preferably, but this car cost is very high, is difficult in multi-point and wide-ranging maintenance department and is equipped with comprehensively.
In sum, hot-mix asphalt mixture has good repair efficiency, but the heat material is vulcanized the dependence of method to big machinery work at present, causes it to be applicable to the road face maintenance that concentrate relatively the position, engineering quantity is bigger; And damage for the bigger small size of pitch road, airport face dispersiveness, or use the cold-repairing material reparation, or it develops into and to a certain degree re-uses the hot-patch material reparation by the time, the functional performance of face can not get in time and effectively recovery.So the construction of repairing to pitch road, airport face needs, provide a kind of and can vulcanize the compound mixing device that bituminous mixture is in time repaired the face small size breakage of pitch road.
