The utility model discloses a fog seal surface drying performance indoor test device is mainly placed in load actuating system, temperature control system, humidity control system and the wind speed control system composition of box in and by the box, the loading actuating system mainly includes lift, loading wheel, guide rail, motor, and the loading wheel links to each other through holding thing platform, connecting rod and holding the board, and it has a motor to hold the board overhead, connecting rod and the guide rail slide bar of wearing to move from vertical and horizontal in respectively, and the guide rail is connected on the counter -force pole, counter -force pole and counter weight rigid coupling. Use the utility model discloses can be better at the actual ambient conditions of indoor simulation to survey the surface drying performance of fog seal material under different load pressure, temperature, humidity and the wind speed condition, appraise the surface drying characteristic between the different fog seal materials, so that carry out the preferred of fog seal material, also can be used for confirming that the construction of a certain fog seal material accomplishes the open required time of traffic simultaneously, it is significant to guideing actual engineering.
