Description
Technical field
The invention belongs to road engineering technical field, and in particular to emulsified asphalt breakdown of emulsion time test technology.
Background technology
Emulsified asphalt is represented as one kind of cold recycled asphalt mixture, due to its convenient, safety and environmental protection of construction, in recent years
It is widely used in the maintenance maintenance engineering on road surface.Emulsified asphalt needs the regular hour that breakdown of emulsion could occur, because which is transported
The difference of defeated distance requires that its de-emulsification speed is also different, according to existing JTG E20-2011《Highway engineering Colophonium and drip
Blue or green test mixture code》, emulsified asphalt de-emulsification speed can be divided into split soon, in split and split slowly.In Practical Project, Hen Duoshi
Work order position Chang Yin causes waste of material and affects construction quality to determining the emulsified asphalt breakdown of emulsion time.It is therefore proposed that a kind of
Emulsified asphalt breakdown of emulsion time method for quantitatively determining has very important significance.
The method of the emulsified asphalt breakdown of emulsion time that current China specification is given, it is difficult to when quantitative determining emulsified asphalt breakdown of emulsion
Between, the breakdown of emulsion time can be caused to there is uncertainty because of individual factor, environmental factorss, breakdown of emulsion illusion etc..CN203551496U is disclosed
Characterize method of testing and the device of emulsified asphalt de-emulsification speed by measuring its current value, though emulsified asphalt can be quantitative determined
De-emulsification speed, but its de-emulsification speed for determining only is the de-emulsification speed of emulsified asphalt liquid, rather than live emulsified asphalt is mixed
The de-emulsification speed of material is closed, lacks the simulation to live practice of construction situation.Though CN 105699634A have carried out one on its basis
Fixed improvement, but method of testing and device are complex, it is impossible to Emulsified Asphalt Mixture situation in transportation is simulated, to bar
The limited site operation directive significance of part is little.
