Constitutive Relation Based on Statistical Damage for Asphalt Concrete Pavement

Based on statistical damage theory,the damage constitutive model of asphalt concrete under triaxial stress is builed.the paper compares the stress-strain curves derived from the model with the stress-strain curves derived from the hyperbolic model respectively at different temperatures and different confining pressures,the results show the strength of asphalt concrete material decreases with increasing temperature and rises with increasing...
