Improving the performance of soft asphalt for coating applications

Monday, 14 November 2016

A study by Egyptian researchers aims to prepare coating materials based on asphalt cement which is a good adhesive and inert to most chemicals but it has unacceptable time to form a solid film.

Asphalt cement AC 60/70 was mixed with blown asphalt of type 115/15 to produce a basic asphaltic material suitable for coatings. Then it was modified using polypropylene (commercial grade) and unsaturated polypropylene ester prepared in lab.

Suitable for mortar coatings

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. They are suitable for mortar coatings as coating and sealer.

The study is published in: Construction and Building Materials, Volume 128, 15 December 2016, Pages 47–56
