市政道路沥青路面现场热再生施工技术的应用

Application of Field Thermal Regeneration Construction Technology of Asphalt Pavement on Municipal Roads

市政道路建设的过程中,沥青路面比较常见,因其具备性能稳定、弹性好、胎噪小、负载能力较强等优点。而随着使用年限的增长,沥青路面会出现一些下沉、开裂等质量问题,导致路面使用性能降低、道路的美观性减弱。为提高我国市政道路施工的质量,应加强对沥青路面热再生技术的合理应用,其主要是将路面材料中的碎石和沥青进行反复利用,在保护生态环境的基础上,实现对资源的合理利用。

In the process of municipal road construction,asphalt pavement is more common,because it has the advantages of stable performance,good elasticity,small tire noise and strong load capacity.With the growth of the service life,the asphalt pavement will have some quality problems such as subsidence and cracking,resulting in the reduction of the road use performance and the weakening of the road aesthetics.In order to improve the quality of municipal road construction in China,we should strengthen the reasonable application of asphalt pavement heat regeneration technology,which is mainly to reuse the gravel and asphalt in the pavement materials and realize the rational use of resources on the basis of protecting the ecological environment.
