#$%^&*AU2020100538A420200521.pdf#####ABSTRACT The invention discloses a multifunctional asphalt aging experimental device, including an aging box body, a vacuum pipe and a vacuum pump. The aging box body is of a closed 5 structure, and is made of glass. The lower part of the aging box body communicates with one end of the vacuum pipe, and the other end of the vacuum pipe communicates with the vacuum pump. A vacuum meter and vacuum degree adjuster is arranged on the vacuum pipe. Asphalt is disposed in the aging box body. The aging box body is of the closed structure, and includes a base, and a cover body component mounted on the base. The base and the cover body 0 component constitute a box body with a cavity inside, and both are made of glass, respectively. The multifunctional asphalt aging experimental device has the beneficial effects that: the device of the present invention is equipped with the vacuum pump and the vacuum pipe to vacuumize the aging box body, so that asphalt aging tests under various vacuum environments and under various conditions such as ultraviolet light, no ultraviolet light, an adjustable ultraviolet wave 5 band range, adjustable ultraviolet radiation intensity can be satisfied. Compared with an existing experimental device with a single function, the multifunctional asphalt aging experimental device improves the experimental efficiency, reduces the cost and is convenient to operate.1/9 1 210 4 Fig.1I sIgo460 60 700 80 Name IDescription nmn ____ Jsample Fig. 2
