石料磨光机及其试验方法的改进

Modification of Accelerated Polishing Machine and its Test Procedure

目前我国在工程试验中所用的石料加速磨光机及其试验规程是在上个世纪80年代初投入使用的,至今已有近20年。本次研究中针对使用过程中发现的问题,参照国际先进标准进行了改进,并对改进后的磨光机和试验规程作了整机性能检验。本文介绍了磨光机改进、磨光值试验方法修订以及整机性能检验的结果。

The Accelerated Polishing Machine has been used in China's highway engineering since the early 1980's .To solve the problems we found in the use,we modified the Machine and its testing procedure with reference to the advanced international standard.In order to check the performance of the Machine,the repeatability and the reproducibility study is conducted.This paper presents the main findings and the results of the research program.
