迄今为止,沥青路面的设计大都采用经验法或半经验法。即使已经有了颇为精确的理论设计方法,但设计参数的选择仍不免带有人为臆测的因素。问题的症结在于对材料性能缺乏彻底的了解。因此,路面设计、路面内的应力应变分析、理论计算等仍停留在理论上,如若付诸于实际应用,还必须从研究沥青材料的性质入手。沥青材料流变学乃是研究沥青材料性质科学的方法本文将着眼于实际应用,介绍什么是流变学、材料的基本性质、测流学(粘度测定
To date, asphalt pavement designs mostly use empirical or semi-empirical methods. Even though there is already a fairly accurate theory of design methods, but the design parameters are still inevitably with the choice of artificial factors. The crux of the problem is the lack of a thorough understanding of the material’s properties. Therefore, pavement design, pavement stress and strain analysis, theoretical calculations are still in theory, if put into practical application, we must start from the study of the nature of asphalt material. Asphalt material rheology is a scientific approach to the study of the properties of bituminous materials. This article will focus on practical applications, describes what is rheology, the basic properties of materials, flow measurement (viscosity measurement
