Description
Technical field
The invention belongs to technical field of road engineering, and in particular to emulsified asphalt demulsification time test technology.
Background technique
A kind of representative of the emulsified asphalt as 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 could be demulsified, because of its fortune
The difference of defeated distance requires its de-emulsification speed also different, according to existing JTG E20-2011 " highway engineering pitch and drip
Green test mixture regulation ", emulsified asphalt de-emulsification speed can be divided into split fastly, in split and split slowly.In practical projects, Hen Duoshi
Work order position Chang Yin causes waste of material and influences construction quality to that can not determine the emulsified asphalt demulsification time.It is therefore proposed that a kind of
Emulsified asphalt demulsification time method for quantitatively determining has very important significance.
The method for the emulsified asphalt demulsification time that China's specification provides at present, it is difficult to when quantitative determining emulsified asphalt demulsification
Between, it can cause to be demulsified the time in the presence of uncertain because of individual factor, environmental factor, demulsification illusion etc..CN203551496U is disclosed
The test method and device of emulsified asphalt de-emulsification speed are characterized by measuring its current value, though emulsified asphalt can be quantitative determined
De-emulsification speed, but de-emulsification speed of its measurement is only the de-emulsification speed of emulsified asphalt liquid, rather than live emulsified asphalt is mixed
The de-emulsification speed of material is closed, the simulation to live practice of construction situation is lacked.Though CN 105699634A has carried out one on its basis
Fixed improvement, but test method and device are complex, Emulsified Asphalt Mixture situation during transportation can not be simulated, to item
The limited site operation directive significance of part is little.
Summary of the invention
The test method of the solution emulsified asphalt that the object of the present invention is to provide a kind of based on compression strength demulsification time.
Technical solution:
Emulsified asphalt demulsification time tester based on compression strength, including test device includes Emulsified Asphalt Mixture
Unconfined compressive strength mold, constant weight iron block, ingot stripper, UTM universal testing machine.
Further, unconfined compressive strength the mold high 120mm, diameter 100mm.
Further, the constant weight iron block quality is 6.55kg.
The emulsified asphalt demulsification time test method based on compression strength, comprising the following steps:
Step 1, Emulsified Asphalt Mixture is put into unconfined compressive strength mold；
Step 2, quality constant weight iron block is placed in Emulsified Asphalt Mixture, the health different time；
Step 3, Emulsified Asphalt Mixture is demoulded, and tests its compression strength on UTM universal testing machine；
Step 4, the Emulsified Asphalt Mixture compression strength value of more different conditioned times, when Emulsified Asphalt Mixture resistance to compression
When intensity reaches maximum, corresponding to conditioned time be emulsified asphalt the demulsification time.
Further, the quality of the Emulsified Asphalt Mixture needed in step 1 is 1900g.
Further, in step 3, the loading speed of UTM is 200mm/min.
The utility model has the advantages that emulsified asphalt provided by the invention based on compression strength is demulsified time test compared with prior art
Method is simple and fast, can above simulate the demulsification situation in Emulsified Asphalt Mixture transportational process to a high degree, more accurately obtain
The practical emulsified asphalt in scene is demulsified the time, reduces unnecessary human error, provides reliably technological guidance for engineering construction.
Detailed description of the invention
Fig. 1 is the relational graph of Emulsified Asphalt Mixture compression strength and conditioned time.
Specific embodiment
The present invention is the emulsified asphalt demulsification time test method based on compression strength, be the steps include:
(1) Emulsified Asphalt Mixture mixed is put into unconfined compressive strength mold；
(2) quality constant weight iron block is placed in Emulsified Asphalt Mixture, health 2,3,4,5,6,7h respectively, simulation emulsification
The state of asphalt during transportation；
(3) it will be demoulded by the Emulsified Asphalt Mixture of regulation conditioned time, and using UTM universal testing machine with constant
The compression strength of loading speed test Emulsified Asphalt Mixture；
(4) the Emulsified Asphalt Mixture compression strength value of more different conditioned times, the maximum emulsified asphalt of compression strength
Mixture, corresponding to conditioned time be emulsified asphalt the demulsification time.
Above-described emulsified asphalt based on compression strength is demulsified time test method, the emulsification drip needed in step 1
The quality of green mixture is 1900g.
Above-described emulsified asphalt based on compression strength is demulsified time test method, in step 3, the load speed of UTM
Rate is 200mm/min.
Below in conjunction with specific example, the invention will be further described.It should be understood that following embodiment is merely to illustrate this hair
It is bright not for limiting the scope of the invention.
The emulsified asphalt demulsification time is measured, the specific steps are as follows:
Step 1, a certain amount of slow breaking emulsified asphalt for needing to measure is added in emulsified asphalt storage box, evaporation residual
Object content is 63.5%；
Step 2, the Emulsified Asphalt Mixture test specimen that 1900g fix level is matched is added in unconfined compressive strength mold；
Wherein, this mix type being added is AC-25, and gradation situation is as shown in table 1；
Table 1.AC-25 mixture gradation situation:
Step 3, the iron block of 6.55KG is placed in Emulsified Asphalt Mixture, the health different time；
Step 4, Emulsified Asphalt Mixture is demoulded, and tests its compression strength using UTM universal testing machine；
As shown in Figure 1, step 5, the corresponding conditioned time of the maximum Emulsified Asphalt Mixture of compression strength is to emulsify drip
The blueness demulsification time.
