沥青路面是指在矿质材料中掺入路用沥青材料铺筑的各种类型的路面。沥青结合料提高了铺路用粒料抵抗行车和自然因素对路面损害的能力,具有路面平整少尘、不透水、经久耐用的特点。因此,沥青路面是道路建设中一种被最广泛采用的高级路面(包括次高级路面)。随着工农业生产水平的提高,大吨位(重荷载)货物运输越来越频繁。重荷载运输有着较高的效率和生产效益,为此公路设计施工人员要建造出高质量的公路,以满足社会发展的要求。
Asphalt pavement refers to the various types of pavement paved with asphalt material in mineral materials. Asphalt binder increases the ability of paving granite to resist road and natural factors damaging the pavement, has the characteristics of less dust, impervious to water and durable. Therefore, asphalt pavement is one of the most widely used high-grade pavement (including sub-high pavement) in road construction. With the improvement of industrial and agricultural production levels, large-tonnage (heavy-load) cargoes are transported more and more frequently. Heavy-load transportation has high efficiency and production efficiency, so highway design and construction workers to build high-quality roads to meet the requirements of social development.
