FIELD: construction.
SUBSTANCE: invention relates to construction, namely to compositions of construction materials, such as mastics, which can be used in repairing roofing, or for waterproofing pipes. Bitumen-polymer cement includes petroleum bitumen, plasticiser, filler, water, asbestos, bitumen mixture is used as petroleum bitumen, which includes oil road bitumen BND 60/90 and bitumen for construction BN 90/10, plasticiser used is plasticiser of styrene-butadiene-styrene type, as filler there used is fibrous polypropylene fibre.
EFFECT: invention improves operational characteristics of the cement, namely resistance to ultraviolet light, reduces flammability and increases frost resistance.
