Zusammenfassung:	The effect of the high-melting paraffin content in petroleum paving asphalts on their adhesive properties was analyzed. The paraffin content was varied by adding petrolatum – high-melting paraffin concentrate, the closest in structure to asphalt paraffins (confirmed by IR spectroscopy) – to the asphalts. The adhesive properties of the asphalt binder were evaluated with the contact angle of wetting on glass and polished marble plates and according to GOST 11508–74. It was shown that a contentunder 5% virtually does not worsen its adhesive properties.
