Improvement performance of soft asphalt for coating applications

This study aims to prepare coating materials based on asphalt cement AC 60/70 which is good adhesive and inert to most chemicals but it has unacceptable time to form solid film. In this research, AC 60/70 was mixed with blown asphalt of type 115/15 to produce a basic asphaltic material suitable for coating then it was modified using polypropylene (commercial grade) and unsaturated polypropylene ester prepared in lab. The coatings were applied on prepared mortar cubes for studying their performance comparing to commercial one. The study revealed that the prepared coatings performed much better than that commercially produced.
