利用沥青路面原材料质量指标检测数据,通过单粒级集料加工级配变异性,并用灰色理论分析单粒级级配变异性对合成级配的影响,从而研究原材料质量的变异性及其对沥青混合料路用性能的影响。研究结果表明,可以通过集料加工场地、集料破碎工艺、破碎机产量均衡性、集料加工筛孔配置、除尘设备选用、碎石设备调试等方面加以改进,以减小集料加工变异性、保证沥青混合料的质量稳定性。 By using the raw material quality index of asphalt pavement to test the data, through the grading variability of single-particle aggregates processing, and using the gray theory to analyze the effect of single particle gradation variability on the composition gradation, the variability of raw material quality and its influence on asphalt Impact of mix road performance. The research results show that it can be improved through aggregate processing site, aggregate crushing process, crusher output balance, aggregate processing sieve configuration, dust removal equipment selection, gravel equipment debugging and so on, in order to reduce the variability of aggregate processing , To ensure the quality of asphalt mixture stability.
