粗集料磨光值试验过程繁复且周期较长,很多细节问题不容易把握和控制。该文以对现行规程的详细解读、现行试验设备的改进以及试验关键控制因素为切入点,结合与美国AASHTO相关规程的对比,分析粗集料磨光值试验中易出现的问题,并提出相应的改进措施。通过试验验证,磨光值试验的成功率和准确性均得到提高。 Rough aggregate abrasion test process is complicated and long cycle, many of the details of the problem is not easy to grasp and control. In this paper, a detailed interpretation of the current regulations, the improvement of the existing test equipment and the key control factors of the test are taken as starting points, the problems appearing in the test of the coarse aggregate abrasion value are analyzed with the comparison with the related AASHTO regulations in the United States, Improvement measures. Through the experimental verification, the success rate and accuracy of the polishing value test are improved.
