近年来,以路面材料现场热再生为特点的养护车不仅具备了传统功能,而目在工艺设计和应用技术方面进行了大胆创新,功能更为完善,而目具有突出的经齐和环境保护意义。高等级道路,尤其是高速公路具有修建标准高、承载能力大、行车速度快和使用寿命长等主要特点。由于我国的高等级道路,特别是高速公路的建造历史较短,设计和施工质量相对较差,因此道路的早期损坏表现较为严重。笔者曾在京深高速河北段、河南段及山西太旧高速忻州段和国道307、208等高等级沥青混凝土道路进行长期实地观测和统
In recent years, the maintenance vehicle characterized by the thermal regeneration of pavement materials not only possesses the traditional functions, but also makes bold innovations and more perfect functions in terms of process design and application technology, and has the prominent significance of passing Qi and environmental protection . High-grade roads, especially the expressways, have the main features of high standard of construction, large carrying capacity, fast driving speed and long service life. Due to the short history of construction of high-grade roads in our country, especially expressways, and the relatively poor quality of design and construction, the early damage to the roads is more serious. The author has long-term field observations and systems in high-grade bituminous concrete roads such as Beijing-Shenzhen Expressway Hebei section, Henan section, Shanxi too-old high-speed Xinzhou section and State Road 307,208
