Study of temperature correction for back calculation moduli of AC

Based on the testing deflection basins measured by Falling Weight Deflectometer(FWD) of 7 cm asphalt pavements,the structure layer d moduli of asphalt pavement are back calculated by the system identification method,then the corresponding relation between the back calculation moduli deflection of asphalt pavement and AC representative temperatures are analyzed and the relevant temperature correction equations of back calculation moduli are developed.According as the above research,the continuation of asphalt pavement thickness and back-calculated moduli are done by the method of equivalent layer theory,finally,the synthesis temperature correction formula for different thickness asphalt pavement is given.
