Description
Technical Field
The invention relates to the field of asphalt detection equipment, in particular to heating sorting equipment used in a process of detecting asphalt content by a combustion method.
Background
The combustion method for measuring the content of the asphalt binder in the hot-mixed asphalt mixture is to place the hot-mixed asphalt mixture into a 538 ℃ combustion furnace, and the asphalt binder is combusted. And calculating the asphalt content in the mixture according to the mass difference between the mixture before and after combustion.
During the burn test, some mass is usually lost for most mineral aggregates (usually less than 0.4%). The measured mass loss of the hot-mix asphalt mixture during the burn test consisted of mass loss of the asphalt binder and mass loss of the aggregate. The mass loss of aggregate is subtracted from the total mass loss measured to be the mass loss of the asphalt binder. And calculating the asphalt content or the asphalt-stone ratio according to the mass loss of the asphalt binder and the mass of the hot-mixed asphalt mixture before the combustion test. In order to improve the measurement accuracy of the test method, a calibration test is carried out to measure the mass loss of each type of mineral aggregate under the same test conditions and calculate the calibration coefficient, namely the correction coefficient, of each type of mineral aggregate, which is a necessary step in the combustion method detection.
To improve the accuracy of the asphalt content measurement, a set of calibration sample tests should be performed on each type of mix to determine the calibration coefficients for that mix. The conventional correction coefficient is obtained as follows: the calibration test should be completed before the accepted test is performed. This calibration test should be performed each time there is a change in the mix composition or the grading design. If the calibration factor for a certain mix exceeds 0.5% due to a broken mineral aggregate, or poor mix, the test temperature should be reduced to 482 + -5 deg.C and the calibration factor obtained at 482 deg.C used.
The main improvement of the combustion method measurement mode at the present stage is to improve the sampling mode of the core material to make the result more accurate, or adopt a scientific recording mode to record correction coefficients of multiple batches, so as to quickly look up the correction coefficients according to file management and avoid the reciprocating operation of the correction coefficients, while the traditional calculation of the correction coefficients requires multiple times of measurement and calculation, sometimes limited by the conditions of the material itself, and cannot necessarily obtain accurate values, and the combustion method has long preparation before entering a combustion furnace, complex steps and low precision.
