Temperature Adjustment for Back Calculation Moduli of Asphalt Pavement

Xudong Zha

Abstract

The Structure layer moduli of asphalt pavements are back calculated with the homotopy method according to the deflection basins measured by Falling Weight Deflectometer (FWD). The regression models for relating the back calculation moduli of asphalt surface to the temperatures are analyzed. So, the equations for temperature adjustments of back calculation moduli are developed.
