Temperature management system and method of asphalt pavement steel deck

摘要

PROBLEM TO BE SOLVED: To provide a temperature management system for an asphalt-paved steel floor slab, the system materializing reduction in the fatigue damage of the steel floor slab by using the stiffness of an asphalt pavement on the steel floor slab.SOLUTION: The temperature management system for an asphalt-paved steel floor slab comprises: heat-exchanging parts 4a to 4c for cooling asphalt layers 2, 8 of the asphalt-paved steel floor slab; a damage estimation device 12 for estimating damage received by the asphalt-paved steel floor slab caused by the traveling of a vehicle 11; and a control device 22 for controlling heat exchange amount of the heat-exchanging parts 4a to 4c on the basis of the estimated damage.SELECTED DRAWING: Figure 1
