Abstract: Aimed at the problems of cold mix plant for resin asphalt concrete that the mechanization level is low and mixing quality is shaky, key technologies for binder adding, mixing system and the control platform were analyzed in depth based on the full grasp of the properties of resin asphalt concrete and resin curing materials. The working procedures and structural parameters were designed, based on which a cold mix plant for resin asphalt concrete was developed. Practical use shows that the machine functions well and yields quality product.
Key words: resin asphalt concrete; mixing plant; numerically controlled addition; intelligentization

树脂沥青组合体系钢桥面铺装技术是由浙江省交通工程建设集团有限公司等国内3家单位自主研发,截止目前在国内几十座大型钢箱梁桥施工中已得到应用,总体效果良好,且建设成本低。不过由于应用时间相对不长且树脂类固化材料的特殊性质,相关机械施工设备的研制一直处于滞后状态,核心结构层RA(Reisn Asphalt)树脂沥青混凝土拌和设备自动化程度低,尤其是胶结料的添加基本依靠人工,造成拌和工效低、控制精度欠缺、施工连贯性不足等问题。为此,亟待研制一套基于单元智能化技术平台的树脂沥青混凝土搅拌设备,实现树脂沥青流变物的数控添加,提升搅拌系统的智能化水平,进一步确保树脂沥青混凝土拌和质量。
