Abstract :
In this paper, relaxation characteristics of asphalt concrete pavement with reflective crack are proposed under traffic load. Normal stress is reduced with time, and stress relaxation is obvious. The chief reason of crack propagated under symmetrical load is normal stress, not shearing stress. Change extent of maximum vertical deflection is not obvious with relaxation.
