集料加速磨光机用于室内模拟汽车轮胎对公路路面的磨光作用，通过对路面所用骨料进行加速磨光，借以测得骨料的磨光值，以评价骨料的抗磨光性能,从而为选用合适的面层骨料铺筑不同摩檫系数要求的路段以及为合理开发利用石料资源提供科学依据，为缩短防滑路面的研究周期创造条件，为研制优质人造骨料提供技术参考。

Aggregate accelerating sander is used to simulate the polishing effect of auto tires on highway pavements. By accelerating and polishing the aggregates used in pavements, the calendering value of aggregates is measured to evaluate the anti-wear performance of aggregates. Therefore, in order to select suitable surface layer aggregates to lay the road sections with different Capricorn coefficient requirements and provide scientific basis for rational development and utilization of stone resources, to create conditions for shortening the research cycle of non-slip road surface, and provide technical reference for the development of high quality artificial aggregate.
