The invention relates to a non-cured rubber asphalt waterproofing coating with flame retardance property. The non-cured rubber asphalt waterproofing coating is prepared from the following raw materials in parts by weight: 35-55 parts of petroleum asphalt, 5-25 parts of softener, 2-8% of flame retardant, 0.1-3 parts of antiaging agent, 5-20 parts of filling agent, and 0.1-2 parts of modifier. The non-cured rubber asphalt waterproofing coating disclosed by the invention has flame retardance property, the flame-retardant problem of a hot-melt waterproofing material can be effectively solved, the non-cured rubber asphalt waterproofing coating is convenient to construct, reliable to adhere, and self-healing, the non-cured rubber asphalt waterproofing coating and a self-adhesion modified asphalt waterproofing sheet material are composed to form a waterproofing system, and the water leakage and channeling problems caused by cracking of a waterproof layer due to deformation of a base layer can be effectively solved.
