Problems solved by technology

The common test method of light transmittance of bright-colored asphalt mainly adopts visual inspection, and the rating method is simple and simple. It is often used in recent years, but because of its greater subjectivity, the degree of quantification is not high, and the comparison results are inconsistent.
At the same time, in the past, the light transmittance meter was used to measure the light transmittance, which required high precision of the light test. The light source and the place where the light source was received needed to be precisely measured by large-scale instruments to ensure the test accuracy. At the same time, there were also requirements for the intensity emitted by the light source. The detection process of the entire light transmittance is cumbersome and inefficient
The traditional transmittance detection device and test method are single, and the light source is single, so it is impossible to test and compare the transmittance of multiple light sources at the same time; To objectively reflect the light transmittance performance of other light sources, it is necessary to stop the test process and replace the bright-colored asphalt material, and the error of the light transmittance results is often large
On the other hand, the traditional light transmittance test process is not aimed at bright-colored asphalt samples. The preparation of samples and test panels is cumbersome, requiring a large amount of samples, changing sample shapes, complex film forming technology, and cumbersome procedures.
At the same time, the calculation and checking methods of the light transmittance of bright-colored asphalt are also different, and the contrast is not strong
