Abstract

This article presents the results of research of processes of deformation and destruction of asphalt concrete pavements under cyclic loads. As the ground for such approach to estimation of the asphalt concrete properties served the proof that regardless of the composition and structure of asphalt concrete with an equal amount of elastic (viscoplastic) bonds possess the same relaxation ability. This situation is a significant feature of the behaviour of asphalt concrete, which opens the way for the development of certain approaches to the analysis of their properties, evaluation of reliability and durability. The promising methodology for the comparative assessment of fatigue and cyclic durability of asphalt concrete by exploring the complex set of elastic and viscoplastic bonds in their structure depending on the temperature, magnitude, and modes of action of the loads is proposed in the presented work. In the future, the establishment of patterns of behaviour of asphalt concretes with the same set of elastic bonds is allows to optimize compositions based on the principles of temperature-structural analogy that is relevant in studying fatigue and cyclic durability as well as low-temperature crack resistance and shear stability.

沥青混凝土路面的抗疲劳性能。潜力的特殊性和评估

本文介绍了沥青混凝土路面在循环荷载作用下的变形和破坏过程的研究结果。作为这种估计沥青混凝土性能的方法的基础，证明了无论沥青混凝土的成分和结构如何，具有等量弹性（粘塑性）粘结的沥青混凝土都具有相同的松弛能力。这种情况是沥青混凝土性能的一个重要特征，这为开发某些方法来分析其性能、评估可靠性和耐久性开辟了道路。本文提出了一种很有前途的方法来比较评估沥青混凝土的疲劳和循环耐久性，通过探索其结构中取决于温度、荷载大小和荷载作用模式的复杂弹性和粘塑性粘结。未来，建立具有相同弹性粘结的沥青混凝土的行为模式，可以基于温度-结构类比原理来优化成分，这与研究疲劳和循环耐久性以及低温抗裂性和剪切稳定性有关。
