Abstract

Abstract

In order to compare the improvement effects of stress concentration in airport rigid pavement joint notches caused by different chamfer shapes, and evaluate the effect of the chamfer on pavement performance, a finite element model of pavement joint opening was established by using ANSYS software, the joint loading-transfer character was simulated by using beam and spring elements, Boeing777 was adapted as aircraft load, the loading stresses and temperature stresses for 6 different chamfer forms at the edges of the joint openings were analyzed eontrastively, and the pavement roughness and friction coefficient were tested in field. Test result shows that all chamfers can improve the stress status at the joint opening edges, the closer the position from the joint opening is, the higher the improvement effect is; 6 chamfers have different improvement effects, and the arc chamfer with 6 mm radius is the best one; the effects of all chamfers on the roughness and friction coefficient are less, and all satisfy the technique requirements.
