本文介绍了一种利用实测材料基本性质的沥青路面结构设计法。虽然确定材料基本性质的实验方法目前已有明确规定,但因有一些陈旧的试验不实用(时间长,费用高),因此,根据各种材料的大量试验结果建立了主要用于沥青混合料和粒料的推算法。文中评述了下列各项设计要素:路面行车质量标准,荷载条件,层状体系的应力和应变,道路材料的基本性质和气候因素。提出了开裂和车辙的模型。发表了现场实试验证的结果。对于路面设计法,介绍了两种方法。第一种是纯理论的方法,第二种方法较为近似,但比第一种简单,所以较实用。
In this paper, a method of designing asphalt pavement using the basic properties of measured materials is introduced. Although the experimental methods for determining the basic properties of materials have been clearly defined at present, some of the old experiments are not practical (long time and high cost). Therefore, based on a large number of experimental results of various materials, Gravimetric method. The paper reviews the following design elements: road traffic quality standards, load conditions, stress and strain in layered systems, basic properties of road materials, and climatic factors. Proposed cracking and rutting model. Published a field test results. For the pavement design method, two methods are introduced. The first is a purely theoretical approach, the second is more approximate, but simpler than the first, so more practical.
