In this study the impact of truck tire type, inflation pressure, speed, and axle load was examined by measuring depth deflections in two pavement structures (one thick, one thin) instrumented with multidepth deflectometers (MDD's). Measured depth deflections under truck loadings were converted into average vertical compressive strains in the pavements layers. The measured subgrade strains were used to estimate the time to rutting failure. Deflections measured at the bottom of the asphaltic concrete layer were used to calculate the surface curvature index which was then translated into tensile strains at the bottom of the layer. This report develops multiple linear regression models to predict the relationship between dependent variables (subgrade strain, tensile strain at the bottom of asphalt layer) and independent variables (speed, lateral offset, asphalt layer temperature, and axle loads).
