Abstract

The invention discloses a rapid cooling device for an asphalt test piece. The rapid cooling device comprises an integral frame and a cooling fan, wherein the integral frame comprises an upper-layer test piece pedestal and a lower-layer mounting pedestal, the upper-layer test piece pedestal and the lower-layer mounting pedestal are the same in structure, vertically upward vertical rods are fixedly mounted at four corners of the lower-layer mounting pedestal, the upper ends of the vertical rods are fixedly connected with the upper-layer test piece pedestal, the upper-layer test piece pedestal is used for placing an asphalt test piece, the cooling fan is fixedly mounted on the lower-layer mounting pedestal, the cooling fan is used for cooling an asphalt test piece placed on the upper-layer test piece pedestal, the upper-layer test piece pedestal comprises two groups of longitudinal rods and two groups of transverse rods, the longitudinal rods and the transverse rods are fixedly connected end to end to form a right-angle quadrilateral structure, the middle parts of the longitudinal rods are fixedly connected with internal transverse supports, and the other ends of the internal transverse supports are fixedly connected with the other group of longitudinal rods. The cooling speed of the asphalt test piece can be increased, the test period is greatly shortened, and the quality of the asphalt mixture is rapidly and effectively controlled.

Description

technical field [0001] The invention belongs to the technical field of municipal and highway engineering construction, and in particular relates to a rapid cooling device for asphalt test pieces. Background technique [0002] At present, the asphalt specimens of municipal and highway projects are usually cooled by natural cooling after the production is completed.
