Asphalt concrete mixtures modified with epoxy asphalt BTNE have been researched and used in many developed countries around the world. The use of BTNE as the surface layer for heavy-duty pavements as well as a coating of steel bridge decks has given good results such as clearly overcoming some disadvantages of ordinary asphalt pavements. The fact that there have been many early failures of asphalt concrete pavements on major national highways in Vietnam so that the study of improved materials is necessary. This article presents some results of the experimental research in laboratory on Marshall stability Marshall flow remaining stability and wheel tracking depth of asphalt mixture using epoxy asphalt BE . These properties were compared with that of asphalt mixture using PMB-III with the same aggregate to evaluate the advantages of of the asphalt mixture modifed with epoxy asphalt. The results of this study show that Marshall stability and rutting resistance of BTNE are superior to those of polymer asphalt concrete so it is necessary to have further studies on BTNE to soon apply in asphalt pavements of high-class highways in Vietnam. Keywords bitumen-epoxy epoxy asphalt concrete polymer-modified asphalt Marshall stability Marshall flow remaining stability rutting resistance. 2022 University of Transport and Communications 189 Tạp chí Khoa học Giao thông vận tải Tập 73 Số 2 02 2022 189-201 Tạp chí Khoa học .
