Description

The highly concentrated modified emulsifying asphalt thick slurry material of the middle temperature induction type of pre- breakdown of emulsion microwave and its preparation Method
Technical field
The present invention relates to a kind of asphalt material for repairing maintenance for asphalt pavement, and in particular in a kind of pre- breakdown of emulsion microwave The highly concentrated modified emulsifying asphalt thick slurry material of warm induction type and its compound method.
Background technology
For the asphalt pavements such as each standard highway, urban road, concrete bridge bridge floor, tunnel Covered face of Smooth Slide, airfield pavement, water is damaged Bad is a kind of more typical disease form, mainly in construction because mixture temperature isolation, the isolation that gathers materials, be compacted deficiency and Seep water the paving local for causing.In addition, the flowing pressure for having vehicular load powerful when passing through will wash away repeatedly asphalt and , first there is purt slurry phenomenon, will subsequently be further developed into as pit in semi-rigid type base surface.
At present, for the maintenance mode of this common pit disease mainly has in three：First, using cut-back asphalt class, Emulsified asphalt class cold-repairing material is emergent to be repaired, and the punishment but this mode can only be met an urgent need is saved bit by bit many etc. pit, then unified milling Plane is slotted, and carries out concentration repairing with heat mixture；Second, carry out slotting, vulcanize using heat mixture, but this mode is often Limited by material source.In fact, the material quantity very little of single or a small amount of pit, according to 4cm depths, 1m2Pit only calculates materials For 100kg, and for Highway Maintenance, as long as owner often requires that appearance, one pit is just repaired as early as possible, then, it is right For contractor, so little material quantity is difficult to meet.Since for a large-scale mixing station of such as 3000 types, one pot Material at least 3000kg, and one pot of a mix of can not possibly starting shooting, so only the large-scale mixing station of periphery is being spread for large area pitch During dress layer construction feed, it is maintenance contractor mix heat mixture a bit in passing.So result in pit to repair in time, There is the pit repairing of storage type.Even if some contractors have bought substantial amounts of heat mixture in advance, because the same day be difficult to be finished and Stock ground is lumpd in a large number, before upper road is repaired, expend half manually digging material, entrucking, being otherwise difficult by heating car is carried out Heating, can at most reduce efficiency of construction more than 50%, and this pit repairing high for original construction cost more can not be timely. 3rd, organic hydraulic material is combined using MOH and is repaired, but be because that MOH materials employ traditional emulsified asphalt, ground Only bleed, condensation, shaping being carried out by natural conditions after pressure, needing 3-4 hour ability open to traffic of experience, this is spread for pitch For the routine maintenance in face, owner is difficult to receive.
