摘要
通过在OGFC沥青混凝土中添加橡胶粒,来提高路面的降噪效果。该文通过对橡胶粒OGFC混合料设计中的级配选择、设计步骤等的研究,并通过室内试验,分析了橡胶粒掺量对混合料路用性能的影响规律,提出了建议的橡胶粒OGFC的材料组成。
It is to enhance the noise-reducmg effect of pavement by admixing the rubber grain into OGFC asphalt concrete.The article analyzes the influence rule of rubber grain admixture on the mixture road performance by studying the gradation selection and design step in the design of rubber grain OGFC mixture and the indoor experiment,and puts forward the material composition of the suggested rubber grain OGFC.
