Description
Technical field
The present invention relates to a kind of pitches, and in particular to a kind of warm mixed epoxy bitumen and preparation method thereof.
Background technique
With being continuously increased for highway mileage, highway bridge quantity also increases therewith.However, also exposing some ask
Topic, wherein being accounted for disease caused by the water-proof tack coat failure between bridge deck pavement and between pave-load layer and panel larger
Ratio causes attention of the people to bridge deck pavement material and technique.As bridge floor interlaminar bonding material, by adding in pitch
Add bituminous epoxy obtained from epoxy resin that there is preferable effect.However, the viscosity due to bituminous epoxy is larger, in construction
It is required that construction temperature is higher, also there is certain operable time, so increasing difficulty of construction；In addition, adding in pitch
After adding epoxy resin, pitch can be made to become fragile, flexibility is deteriorated, bad with the followability of bridge panel.In order to solve these problems,
Warm mix technology need to be taken to reduce the construction temperature of bituminous epoxy, and improve flexibility.
There are mainly three types of modes for warm-mixed asphalt technology: first is that using the higher emulsified asphalt of evaporated residue content, 80
DEG C~120 DEG C at a temperature of with building stones mix, which is about 30 DEG C~50 DEG C low compared with the temperature of hot asphalt；Second is that being mixed in mixing
Water (or aqueous solution of surfactant) and pitch are added simultaneously in mix tank when material, due to the presence of water, make asphalt foaming,
Reach viscosity reducing effect.But above two method can generate a large amount of vapor, easily cause equipment corrosion, stone also frequently occurs
Powder conglomeration even causes mixing equipment blockage problem, makes troubles to production.Further, since remaining non-volatile moisture is retained in
In mixture, mixture initial performance will affect.The third method is that warm-mixing agent is added in pitch in advance, then take with
The same production method of common hot-mix asphalt mixture is easy to be received by production unit convenient for operation.This kind of method passes through
Warm-mixing agent is added in pitch in advance, reduces the high temperature viscosity of pitch, changes the viscosity-temperature curve of pitch, to reduce drip
The green mix temperature with building stones, reaches warm mix effect.But presently used warm-mixing agent leads to while reducing asphalt high-temperature viscosity
The reduction that often can also cause 60 DEG C of viscosity of pitch, makes the high-temperature stability of asphalt incur loss；Or on the contrary, not dropping
When low 60 DEG C of viscosity, the loss of pitch ductility can be caused, to reduce the cryogenic property of pitch.In short, presently used
Warm-mixing agent is while making pitch reach warm mix effect, is high-temperature behavior to lose pitch or cryogenic property as cost
