泡沫沥青冷再生技术具有施工便捷、工程造价低、节能环保等特点,在改扩建工程中解决路面基层裂缝问题,是半刚性基层所不可替代的。结合唐津高速公路改扩建工程中泡沫沥青冷再生场拌法施工路面基层的工程实践,阐述泡沫沥青冷再生工艺技术原理和泡沫沥青发泡机理,以及泡沫沥青冷再生场拌法施工工艺与施工质量控制措施。
Asphalt cold recycling technology with convenient construction, low construction cost, energy saving and environmental protection, etc., in the reconstruction of expansion project to solve the problem of cracks in the grassroots road surface, semi-rigid grassroots irreplaceable. Combined with the engineering practice of the pavement base course of foam asphalt cold reclamation field in the reconstruction and expansion project of the Dangjin Expressway, the technical principle of foamed asphalt cold reclamation process and foaming asphalt foaming mechanism are expounded, and the construction technology and construction quality of foam asphalt cold reclamation field mixing method Control measures.
