水泥稳定旧沥青路面材料这一路面再生技术目前已在我国得到了较为广泛的应用,国内外学者也对这类材料的路用性能开展了较为广泛的研究。在实际使用中发现,由于旧沥青路面材料中的沥青结合料是感温性材料,再生混合料的强度特性必然会受到温度的影响。而水泥稳定;令再生的旧沥青路面材料一般作为基层使用,对其强度要求较高。同时,弯沉仍是我国目前的沥青路面设计指标,温度对基层强度的影响必然也会导致路面弯沉的变化,这对工程质量控制无疑也是非常重要的。因此,有必要研究温度对其强度的影响,以利于指导旧沥青路面再生的设计和施工。
Cement stabilized asphalt pavement material This pavement regeneration technology has been widely used in our country at present, domestic and foreign scholars also carried out a more extensive research on the road performance of such materials. In actual use, it is found that the strength characteristics of the recycled mixture will inevitably be influenced by the temperature because the asphalt binder in the old asphalt pavement material is a temperature-sensitive material. While the cement is stable; the recycled old asphalt pavement materials are generally used as a grassroots level and require higher strength. At the same time, the deflection is still the current design index of asphalt pavement in China. The influence of temperature on the strength of the grass-roots will inevitably lead to the change of pavement deflection. This is undoubtedly very important for project quality control. Therefore, it is necessary to study the influence of temperature on its strength in order to guide the design and construction of the recycling of old asphalt pavement.
