Production process of asphalt cold patch material
The invention discloses a production process of an asphalt cold patch material, and relates to the technical field of road maintenance materials. The production process of the asphalt cold patch material comprises the following steps: carrying out composite modification on matrix asphalt to obtain composite modified asphalt; adding the tackifier and the anti-stripping agent into the composite modified asphalt, heating and stirring, then adding the diluent, uniformly stirring, and cooling to obtain the asphalt cold supplementing liquid; heating the aggregate and the reinforced fiber together, and uniformly stirring to obtain a mixture; and adding the asphalt cold patch liquid into the mixture, and stirring to obtain the asphalt cold patch material. The asphalt cold-patch material prepared in the invention has both high-temperature stability and low-temperature crack resistance, the stability and strength of the asphalt cold-patch material can be enhanced, and the requirement of rapid traffic can be met.
本申请公开了一种沥青冷补料生产工艺，涉及道路养护材料技术领域。一种沥青冷补料生产工艺，包括以下步骤：对基质沥青进行复合改性，得到复合改性沥青；将增黏剂和抗剥落剂加入复合改性沥青中，加热搅拌，再加入稀释剂，搅拌均匀，冷却后即得沥青冷补液；将集料和增强纤维一同进行加热，再搅拌均匀，得混合料；将沥青冷补液加入混合料中，搅拌，即得沥青冷补料。本申请制备的沥青冷补料既能够兼顾高温稳定性能和低温抗裂性能，又能增强沥青冷补料的稳定度和强度，能够满足快速通车的要求。
