Abstract:

In order to provide reference for the anti-shear design and construction of asphalt pavement layer, the mechanical frictional strength between layers of asphalt pavements with different grades of structural layers was studied based on the structural layer combination of existing asphalt pavements in this study. Firstly, the theoretical model of mechanical frictional resistance between asphalt pavement layers is established based on the fractal theory, and the mechanical frictional strength characteristics of asphalt pavement with different grading structural layers combinations are analyzed. Furthermore, the shear tests of asphalt pavement with different grading structural layer combinations were carried out in order to verify the reliability of the theoretical model. The results show that the interlayer surface morphology is greatly affected by the gradation of asphalt mixture. Among them, the gradation combination type AC-13/AC-16 has the largest contact area, followed by AC-13/AC-20 and AC-16/AC-20. The mechanical frictional strength between layers is greatly affected by the combination of upper and lower gradation structure layers under the same load, and the gradation structure layer combination type AC-13/AC-20 has the largest interlayer mechanical friction strength, followed by AC-16/AC-20 and AC-13/AC-16. The theoretical value of the mechanical frictional strength among the interlayers is fitting to the experimental value at the temperature of 20 °C, which indicates that the theoretical model of the mechanical frictional strength among the asphalt pavement interlayers has certain reliability and applicability under this condition.

Key words: asphalt pavement, fractal theory, contact area, shear strength, mechanical friction strength
