本文目的是测定各种材料参数对路面结构疲劳寿命的影响性。目前很多种混合物可以用于路面铺筑,它们有着不同的劲度模量。然而,匈牙利沥青路面设计方法不能适应这一点。沥青层失败的主要原因可能是层底水平张力造成的。产生许多关于路面结构性质的推测,地基、基层、结合料因素及路表因素。在这些推测基础上,我们可以清楚地看到,不同层次的不同参数是影响路面疲劳寿命的最重要因素。
The purpose of this paper is to determine the effect of various material parameters on the fatigue life of pavement structures. At present, many kinds of mixtures can be used for road pavement, they have different stiffness modulus. However, Hungarian asphalt pavement design methods do not adapt to this. The main reason for the failure of bitumen may be the horizontal tension at the bottom of the bed. A lot of speculation about the nature of the pavement structure, foundation, grassroots, bonding materials and road surface factors. Based on these assumptions, we can clearly see that different parameters at different levels are the most important factors that affect the fatigue life of the pavement.
