沥青路面结构和功能的指标要求分析
摘要
随着我国高速公路的迅猛发展,沥青路面作为一种主要的路面结构形式得到了广泛的应用。但高速公路沥青路面在取得量的飞跃的同时,在质的问题上还存在着很大的隐患,我国沥青路面普遍存在耐久性不足和早期破坏严重等问题,其社会影响大,浪费严重,成为目前困扰我国交通建设发展的难点和热点问题。
目前我国通车的公路路面中,约80%以上的路面结构采用了沥青路面,沥青路面结构已成为我国公路建设发展过程中所采用的主要路面结构形式。本文开展了我国沥青路面主要结构形式和功能指标分析的研究。详细的分析了沥青路面结构设计中弯沉值、容许拉应力指标的分析。沥青路面的功能和作用不言而喻是以满足交通车辆安全、舒适通行为目的的,由于公路是暴露在自然环境条件下的土工工程构造物,因此,沥青路面还需满足并适应自然环境条件,本文也对压实度、平整度、宽度、横坡度、厚度(俗称“五度”)等相关功能指标进行了分析。在总结我国现有沥青路面结构使用经验教训,并在充分借鉴国外沥青路面设计与使用经验的基础上,提出了沥青路面结构合理组合形式,并对沥青路面结构设计方法和功能性能进行了系统研究。

The asphalt pavement structure and functions of the index requirements analysis
Abstract
Along with the rapid development of expressway, the asphalt pavement as a main road surface structure form a wide range of applications. But highway asphalt pavement made the leap in quantity at the same time, in the existence problem of a lot of hidden trouble, our country the asphalt pavement widespread durability and early destruction and lack serious problem, its social influence, waste is serious, be at present in our country the construction progress of the traffic with difficult and hot issue.
At present our country open to traffic in the road surface, about more than 80% of the pavement structure used the asphalt pavement, the asphalt pavement structure has e China's highway construction and development process of the main road surface structure form. This paper carried out the asphalt pavement structure in China mainly form and function index analysis research. Detailed analysis of the asphalt pavement structure design of deflection value, allows for the analysis of the indexes of the tensile stress. The function and effect of the asphalt pavement is self-evident is to meet the traffic vehicle traffic safety fort for the purpose of, because the road is exposed to the natural environment conditions of geotechnical engineering structures, there
