Process for producing an improved bitumen by adding polyphosphoric acid and a crosslinkable polymer |
| abstract |
A method for producing a bitumen product with improved properties for use in asphalt road paving is presented. In a preferred embodiment, polyphosphoric acid is added to the heated bitumen and stirred for a period of time. After the polyphosphoric acid is added, one or more sulfur crosslinkable elastomers and one or more sulfur donating coupling agents are added to the heated bitumen and mixed. Alternatively, polyphosphoric acid, sulfur crosslinkable elastomer, and sulfur donating coupling agent may be added to different amounts of bitumen and the bitumen mixed before use to provide the final bitumen product with the desired properties. |
