加速磨光機,公路土工試驗儀器
加速磨光機用于室內(nèi)模擬汽車輪胎對公路路面的磨光作用，通過對路面所用骨料進行加速磨光，借以測得骨料的磨光值，以評價骨料的抗磨光性能,從而為選用合適的面層骨料鋪筑不同摩檫系數(shù)要求的路段以及為合理開發(fā)利用石料資源提供科學依據(jù)，為縮短防滑路面的研究周期創(chuàng)造條件，為研制優(yōu)質(zhì)人造骨料提供技術(shù)參考。
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.
