High-performance foamed asphalt cold-recycled mixture and production method thereof
The invention particularly relates to a high-performance foamed asphalt cold-recycled mixture. The high-performance foamed asphalt cold-recycled mixture is prepared from the following components: pavement asphalt waste, pavement macadam, asphalt, an asphalt active agent, cement and warm water, the production method comprises the following steps: step 1, milling, crushing and screening a damaged asphalt pavement, and stacking according to specifications; step 2, mixing the asphalt active agent into the hot asphalt in proportion; and step 3, blending the recycled material obtained in the step 1 with pavement macadam in proportion, then inputting the mixture into foamed asphalt regeneration equipment for stirring and mixing, and meanwhile, adding the hot asphalt obtained in the step 2, cement and warm water into the equipment to finally obtain the required high-performance foamed asphalt regenerated mixture. According to the invention, the technical indexes of the foamed asphalt regenerated mixture and the structural layer are obviously improved, the problems of poor workability and low strength of the mixture in construction are effectively solved, and the stability of the mixture and the adaptability to construction climate conditions are greatly enhanced.
本发明涉特别指一种高性能泡沫沥青冷再生混合料，由以下组分组成：路面沥青废料、路面碎石、沥青、沥青活性剂、水泥和温水；生产方法，包括以下步骤：步骤一，将破损的沥青路面铣刨、破碎和筛分，分规格堆放；步骤二，将沥青活性剂按比例掺入热沥青中；步骤三，将步骤一获得的回收材料与路面碎石按比例进行参配，然后输入泡沫沥青再生设备中进行搅拌混合，同时在设备中加入步骤二获得的热沥青，以及水泥、温水，最后获得所需的高性能泡沫沥青再生混合料。本发明使泡沫沥青再生的混合料及结构层的技术指标有明显的提升效果，有效地解决了施工中混合料和易性差、强度偏低的问题，并大大增强了混合料的稳定性和施工气候条件的适应能力。
