CORRELATION OF THE ADHESIVE PROPERTIES OF PETROLEUM PAVING ASPHALTS AND HIGH-MELTING PARAFFIN CONTENT
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 content under 5% virtually does not worsen its adhesive properties.
