The invention discloses an improved asphalt sludge thickening apparatus. The apparatus includes a sludge pond provided with a plurality of tilting mud pushing plates, and the front surfaces of the plurality of tilting mud pushing plates are provided with a plurality of cutting plates along the forward direction of the tilting mud pushing plates. A water spraying device is arranged at the bottom end of each tilting mud pushing plate, a guide rail is arranged above the sludge pond, the tilting mud pushing plates move along the guide rail, the guide rail is fixedly connected with vertical telescopic rods, and the sludge pond also is provided with a supernatant liquid extraction device. Sewage flows into the sludge pond and naturally settles on the inclined mush pushing plates, after the settlement is completed, the tilting mud pushing plates push the sludge out of the sludge pond, so that operators are facilitated to clean the sludge, the operation is convenient and the labor intensity issmall.
