Present Trends in Improving Quality of Pavement Bitumen

by Liliana Stelea

Abstract
The article presents the experience with modified bitumen in Romania, especially on national roads. More experimental sectors were set and evolution of the condition is observed. Laboratory tests results are presented for different sources of bitumen and different additives.
Tests were performed according to SHRP methods which are based on performance. Considering SHRP algorithm for temperature and traffic prediction may generate effective asphalt mixtures.

KEY WORDS: modified bitumen, roads materials, roads design.
