Description
Technical field
The utility model relates to a kind of Preparation equipment of bituminous mixture, relates 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, asphalt pavement in use, vital tasks such as bearing takeoff and landing, slide and parking is the basic platform that the airport function is given full play to.But because repeated actions such as load and environmental factors, road face structure in use also can be damaged gradually.Such as diseases such as loose, crack, rut, hole, hole, depressions.The service performance of the face that just affects 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 so that 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 is not subjected to 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, usually reach and namely need about 2 months again to process in lower its final repairing life-span of constantly washing away of traffic load and rainwater.This is a kind of acute repairing measures, can solve the provisional pit repairing that affects safety, but as routine 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 Heavy Traffic.The method of producing at present the hot asphalt blended stock has three kinds: the first 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; The second 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 large 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 larger, and the grating of bituminous mixture and bitumen aggregate ratio are difficult for strict control, affect 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 preferably maintaining process, but this car cost is very high, is difficult to be equipped with in multi-point and wide-ranging maintenance department comprehensively.
