沥青作为道路施工的常见施工材料,在交通基础设施建设中发挥了重要的作用。在我国,有近八成的公路都是以沥青为材料进行施工设计的。一般的沥青道路在设计时确定的道路寿命都是15年左右,而长寿路面的道路在设计其寿命时则需要至少在45年以上,这也是为什么其被称之为长寿路面的原因。为了能够更好的研究长寿路面的性能,本文对重载情况下的长寿路面材料设计问题进行简单探讨。
As a common construction material of road construction, asphalt plays an important role in the construction of transportation infrastructure. In our country, nearly 80% of highways use asphalt as material for construction design. The average asphalt road design life time is determined at about 15 years, while the longevity of the road in the design of its life expectancy at least 45 years or more, which is why it is called longevity pavement reasons. In order to better study the performance of longevity pavement, this paper briefly discusses the design of longevity pavement materials under heavy load conditions.
