Description
Technical field
The invention belongs to Highway Test technical field, it particularly relates to be adhered to a kind of anti-rut agent and building stones
The evaluation method of property.
Background technology
In recent years, because anti-rut agent class product has excellent pavement performance and easy addition manner, in highway construction
Fairly large application is achieved in the market with maintenance.Anti-rut agent part wire drawing during mixing and stirring into plastic optical fibre, is collecting
It puts up a bridge in material skeleton and is crosslinked and forms fiber and steel bar reinforced effect, therefore anti-rut agent and building stones adhesiveness are particularly significant.
At present, anti-rut agent mainly passes through anti-rut agent with building stones adhesiveness there is no Direct Test method and index
Physical property itself and the performance of asphalt reflect indirectly.The physical index of anti-rut agent, mainly including appearance, close
Degree, softening point, melt index etc.；The performance of asphalt, mainly from high-temperature stability, low-temperature cracking-resistance, water resistant damageability
Etc. judgement.These Test model synthetic techniques are complicated for operation, and the used time is longer, it is difficult to evaluate anti-rut agent and building stones to quicklook
The quality of adhesiveness.
This law weight reduction to be used measures the anti-rut agent quality for participating in building stones adhesiveness, but weight reduction must be measured when filling sample
And the quality after cleaning sample.If sample cleaning is unclean, clear up it is inaccurate if the container mass after sample, easily to meter
Calculation causes error.
Invention content
In order to solve the above technical problems, the present invention provides a kind of anti-rut agent and the evaluation method of building stones adhesiveness, it should
Method is easy to operate, quick and precisely, favorable repeatability.
A kind of anti-rut agent of the present invention and the evaluation method of building stones adhesiveness, the evaluation method specific steps are such as
Under：1) by screening used for asphalt mixture of gathering materials, washing, drying, if obtaining the clean dried stone sample of 2.36~9.5mm sizes
It is dry；2) appropriate stone sample is weighed, is denoted as m1, it is put into more than heating and thermal insulation 5h in 180 ± 2 DEG C of baking ovens；3) according to engineering reality
Additive amount, it is several to weigh dry anti-rut agent sample in proportion, is denoted as m2；4) mixing device is preheated into 30min at 180 ± 2 DEG C
Afterwards, stone sample and anti-rut agent are added in simultaneously, stirs 90s；5) mixture is discharged into clean enamel tray, sealer, be put into-
80 DEG C of freezing more than 1h, striping after taking-up are immediately placed in 120 DEG C of baking ovens with shaking table function, and be heated 30min, 100rmp shakings,
It scrapes anti-rut agent to weigh, is denoted as m3；6) using calculating quality sticking ratio Δ=(m2-m3)/m2× 100% for anti-rut agent with
The evaluation index of building stones adhesiveness.
Compared with prior art, the evaluation method of anti-rut agent of the present invention and building stones adhesiveness in different building stones and
After anti-rut agent stirring, how much is amount adhere in stone surface by comparing anti-rut agent, calculating quality sticking ratio Δ=(m2-
m3)/m2× 100%, value is bigger, represents that anti-rut agent and building stones adhesiveness are better.This method is easy to operate, favorable repeatability,
The adhesiveness quality of anti-rut agent and building stones intuitively can be rapidly evaluated, the research and development, construction, production of anti-rut agent are respectively provided with
Great importance.
