Description
Technical field
The invention belongs to emulsified asphalt technology field, more particularly to a kind of evaluation of measuring side of emulsified asphalt storage stability
Method, it is mainly used in the new construction and maintenance project of local road, high-grade highway.
Background technology
The use of emulsified asphalt at home has had the history of more than 20 years, and its good economy and ease of use are general
Logical bi tumenf orr oad is irreplaceable, but the storage stability deficiency brought therewith is brought to the application of emulsified asphalt
Obstacle so that emulsified asphalt can not preserve for a long time, therefore, the storage stability of emulsified asphalt should cause enough attention.
It is existing《Highway engineering pitch and Asphalt Mixture Experiment code》In, method T0655 is mainly steady by storage
It is qualitative be defined container and under the conditions of, after the time as defined in storage, the intensity of variation of emulsified asphalt concentration on vertical direction,
To judge the stability after emulsion storage, it is one of important indicator for influenceing emulsified asphalt property.As pavement usage
Emulsified asphalt, either from the complexity of construction or its pavement performance, emulsified asphalt is more uniform better, stable storing
Property is the smaller the better.But in Practical Project, due to it is pressed for time, normally only detecting the 1d stability into factory's emulsified asphalt, fail
5d stability is detected, the quality testing for emulsified asphalt is not tight to check on, therefore there is an urgent need to quick accurately emulsified asphalt length
Phase storage stability detection method.
Lack at present to emulsified asphalt storage stability quick determination method, and existing method excessive cycle, it is not easy to
Quickly the quality of emulsified asphalt is judged, and then influences materials arrival cycle and emulsified asphalt service life, and influences breast
Change the construction effect of pitch.
The content of the invention
To overcome above-mentioned the deficiencies in the prior art, it is an object of the invention to provide a kind of emulsified asphalt storage stability
Evaluation of measuring method, the 5d storage stabilities of emulsified asphalt are detected using centrifuge, and are brought into corresponding reduction formula, meter
The 5d stable storing angle value of Highway Code requirement is calculated, detection method is convenient, determination efficiency is high.
To achieve the above object, the technical solution adopted by the present invention is：A kind of measure of emulsified asphalt storage stability is commented
Valency method, comprises the following steps：
1) after emulsified asphalt is stirred, load centrifuge tube, cover tightly lid；
2) centrifuge tube is symmetrically put into sleeve pipe；
3) centrifugation machine cap is covered, starts centrifuge, after separation terminates, closes centrifuge, after centrifuge stops operating,
Centrifuge cup is opened, takes out sample；
4) centrifuge tube is slowly taken out from centrifuge, under the influence of centrifugal force, sample is in centrifuge tube into inclination
Shape, specimen height and the liquid height isolated are measured respectively, and bring below equation into and centrifuge stability value is calculated,
In formula：P-centrifugation stable storing angle value, unit：%,
m1- isolate liquid level minimum constructive height, unit:Mm,
m2- isolate liquid level maximum height, unit:Mm,
m3- sample maximum height, unit:Mm,
m4- sample minimum constructive height, unit:Mm,
Calculated value is accurate to after decimal point 2；
5) stability value for being surveyed centrifuge substitutes into polynomial equation y=-0.0019x2In+0.2583x-n, it can obtain
《Highway engineering pitch and Asphalt Mixture Experiment code》Emulsified asphalt 5d stable storing angle value corresponding middle method T0655, n
Span be 5.8~6.
The volume of the centrifuge tube is 10ml, and sampling is about 8ml.
Described centrifuge tube with etc. the water of quality be symmetrically put into sleeve pipe, overall balance when keeping centrifuge rotation.
The rotating speed of centrifuge is 5000~10000 revs/min in step 3, and time overall length is 5~10 minutes.
Emulsified asphalt 5d stable storing angle value≤5%.
The beneficial effects of the invention are as follows：
The evaluation of measuring method of emulsified asphalt storage stability of the present invention, it is by a large amount of laboratory tests, is trying
Test on the basis of result and establish relational expression between two kinds of test methods, centrifuge temperature value detection operation letter in the evaluation method
Just, fast, accurately, it is smaller to substitute into after relational expression the 5d stable storing angle value errors calculated, the true of emulsified asphalt can be represented
Quality.The evaluation method quickly can be judged the quality of emulsified asphalt, and shortens materials arrival cycle and emulsification drip
Blue or green service life, it is effective to play emulsified asphalt pavement performance.
Brief description of the drawings
Fig. 1 is the flow chart of the evaluation of measuring method of emulsified asphalt storage stability of the embodiment of the present invention.
