沥青路面厂拌冷再生施工工艺与质量控制

Construction Technology and Quality Control of Cold Regeneration of Mix Asphalt Plant

沥青路面厂拌冷再生技术可广泛应用于各等级公路及城市道路的沥青路面大中修工程,具有明显的节能减排效果,显著提高了旧路面材料的利用率,经济效益和社会效益明显,具有广泛的推广应用前景。通过河南连霍高速公路工程项目沥青路面厂拌冷再生施工中通过精确控制泡沫沥青生产参数;改进旧路面铣刨工艺;提高旧路面回收料质量等一系列措施保证了冷再生层质量。

Cold regeneration technology of mix asphalt plant can be widely used in the asphalt pavement repairing project of various grade highways and urban roads. It has significant energy saving effect, and can significantly improve the utilization of old pavement materials, the economic and social benefits are obvious. It has broad application prospects. In the cold regeneration construction of asphalt pavement plant of Henan Lianhuo Highway project, the quality of cold regeneration layer is ensured by precisely controlling the foamed bitumen production parameters, improving the milling process of old pavement, improving the quality of old pavement recycled materials and other measures.
