BITUMEN/POLYMER COMPOSITION HAVING IMPROVED MECHANICAL PROPERTIES UNDER COLD CONDITIONS |
摘要 |
The invention relates to a bitumen/polymer composition and to its process of manufacture. The bitumen/polymer composition includes first bitumen base having an intrinsic stability S of greater than 2.5 and/or a degree of peptization Sa of greater than 0.60, and a second bitumen base having an intrinsic stability S of less than or equal to 2.50 and/or a degree of peptization Sa of less than or equal to 0.60, an elastomer and an olefinic polymer adjuvant functionalized by at least glycidyl functional groups. The values of intrinsic stability S and of the degree of peptization Sa are measured according to the standard ASTM D 7157-12. The bitumen/polymer composition exhibits improved low-temperature mechanical properties. |
