Mechanistic-empirical analysis of asphalt pavement fatigue cracking under vehicular dynamic loads

Highlights Dynamic tire forces were estimated on different pavement roughness conditions. Impulse response method was adopted to calculate tensile strains under random dynamic loads. Relative ratios of fatigue life were calculated between static and dynamic loads. An approach was proposed to consider dynamic loads in pavement ME design framework.
Abstract Vehicle-pavement interaction causes dynamic loads and accelerate pavement deterioration. The study provides a methodology to consider dynamic loads in mechanistic-empirical (M-E) pavement design and analysis. The dynamic load coefficients were found increasing as pavement roughness increased or axle loads decreased. The impulse response method was adopted to calculate tensile strains of asphalt layer under random loads. The relative ratios of fatigue life due to dynamic loads were calculated and fitted as a function of axle type, load magnitude, and international roughness index (IRI). The accumulative fatigue damage ratio between dynamic and static loads was proposed for M-E pavement analysis.
