The invention discloses a flexible energy-absorbing type speed bump which is prepared from the following raw materials in part by mass: 10 to 30 parts of gelatinizing agent, 20 to 50 parts of aggregate, 25 to 55 parts of filler, 0.2 to 8 parts of pigment, 10 to 30 parts of diluent and 1 to 20 parts of additive. The gelatinizing agent is a polyurethane adhesive; the aggregate is one or more of carborundum, quartz sand, brown aluminium oxide and finely broken stone; the filler is one or more of heavy calcium powder, talcum powder, mineral powder and silica fume; the diluent is one or more of methylbenzene, ethyl acetate, acetone, dioxane and dimethylformamide; the additive is one or more of a catalyst, a plasticizer, a light stabilizer and an antioxidant. The speed bump only needs to be constructed at the normal temperature, is short in curing time, and after the speed bump is constructed, rapid opening to traffic can be implemented; the cured speed bump also has a certain flexibility and impact resistance; compared with a conventional speed bump, the speed bump disclosed by the invention is low in vibration and more comfortable and safer when a vehicle passes through the speed bump.
