本文针对机场沥青道面转弯区受力状况,设计沥青混凝土试块抗压和剪切试验。根据沥青混凝土试块压剪试验,对沥青混凝土试块在不同温度、不同尺寸条件下的受力状态进行分析,研究沥青混凝土试块的剪切性能和抗压性能。通过对沥青混凝土试块压剪试验的数据进行整理分析,得出以下结论:沥青混凝土试块的剪切性能受温度影响较大,随着温度的升高,沥青混凝土试块的剪切强度和抗压强度显著降低,且降幅较大;沥青混凝土试块的剪切性能与其尺寸有关,随着试块厚度的增加,沥青混凝土试块的剪切强度和抗压强度有所降低。
In this paper, according to the stress conditions in the asphalt pavement cornering area of the airport, the compressive and shear tests of bituminous concrete blocks are designed. According to the compressive shear test of asphalt concrete block, the stress state of asphalt concrete block under different temperature and different dimensions is analyzed to study the shear performance and compressive resistance of asphalt concrete block. By analyzing the data of the compression shear test of the asphalt concrete block, the following conclusions are drawn: The shear properties of the asphalt concrete block are greatly affected by the temperature. As the temperature increases, the shear strength of the asphalt concrete block and The compressive strength of asphalt concrete specimens decreased significantly, and the decrease was larger. The shear properties of asphalt concrete specimens were related to their size. With the increase of specimen thickness, the shear strength and compressive strength of asphalt concrete specimens decreased.
