Estimating the term…
The present invention relates to an asphalt composition comprising a modified bitumen with a hydroxyl-functionalized polymer configured to create a thermally reversible cross-linking network within the composition, wherein the hydroxyl functionalized polymer is selected from the group comprising: hydroxyl functionalized polyolefin thermoplast, hydroxyl functionalized polyolefin elastomer, hydroxyl functionalized polyolefin plastomer.
Modified bitumen comprising a randomly hydroxyl-functionalized polymer or a graft copolymer containing said randomly functionalized polymer and styrene-maleic-anhydride copolymer (PO-graft-SMA), configured to create a thermally reversible cross-linking network within the bitumen wherein the randomly hydroxyl functionalized polymer is selected from the group comprising:
Compatibilizer for asphalt or bitumen comprising PO-graft-SMA wherein the amount of PO is between 60 and 95 wt %, and the amount of SMA is between 5 and 40 wt %, where the PO is a polyolefinic thermoplast, a polyolefin plastomer (POP) or polyolefin elastomer (POE).
Compatibilizer for asphalt or bitumen comprising PO-graft-SMA wherein the amount of PO is between 60 and 90 wt %, and amount of SMA is between 10 to 40 wt %.,
