The invention discloses construction asphalt prepared by utilizing hard deoiled asphalt. Paraffin-based crude oil vacuum residue hard deoiled asphalt, residual catalytic oil slurry after topping, anda modifier are used as raw materials, simple reconciliation is performed under certain conditions, and therefore a series of construction asphalt can be produced; and indexes of the obtained construction asphalt are superior to those of a national standard in China. The problems that a oxidation method and a current chemical condensation method in the prior art have a complicated process and highcosts, and easily produce pollution to the environment are overcome, construction asphalt types are adjustable and controllable, and a goal of maximum utilization of the hard deoiled asphalt is realized. The construction asphalt provided by the invention is produced by adopting a plurality of raw material blending methods, and has a simple process, low costs and obvious advantages.
