冷再生中粒式混合料目标级配范围研究

Study on the Target Gradation Range of Cold Recycle Medium Grain Type Mixture

为了使冷再生混合料的性能得到提高,从影响冷再生混合料的关键因素—级配入手,基于国内外冷再生级配范围的研究和工程应用,通过N法、K法和I法等方法设计级配,经过贝雷法级配检验,得出冷再生中粒式混合料目标级配范围,并通过混合料性能试验,得出按所推荐的级配范围设计的冷再生混合料性能较优。

To improve the performance of cold recycled mixture, from one of the key factors-grada- tion which effects of the cold mixture of renewable, based on the study of the gradation range of cold recy- cled and engineering application at home and abroad,through the N, K and I method designed gradation, and after Bailey method gradation testing, obtained the target gradation range of Cold Recycle medium grain type mixture,through the mixture performance test,draw a conclusion that the cold recycled mixture which design according to the recommended gradation range has good Performance, it can offer some ref- erence for practical application.
