METHOD OF MAKING SULFUR EXTENDED ASPHALT MODIFIED WITH CRUMB RUBBER |
| 摘要 |
The present invention relates to asphalt compositions. The present invention provides for a sulfur rubber asphalt binder composition that includes a base asphalt having a softening point, elemental sulfur, and a crumb rubber material. The crumb rubber material is combined with the base asphalt and the elemental sulfur to create the sulfur rubber asphalt binder composition. The crumb rubber material is present in the sulfur rubber asphalt binder in an amount effective to increase the softening point as compared to the softening point of the base asphalt. |

1. A method of making a sulfur rubber asphalt binder composition comprising the steps of:
mixing the crumb rubber material with the base asphalt at a first predetermined temperature in a high shear blender for first predetermined amount of time to create an asphalt crumb rubber mixture; placing the asphalt crumb rubber mixture in a sealed container in an oven at the first predetermined temperature for a second predetermined amount of time; adding elemental sulfur to the asphalt crumb rubber mixture and mixing for a third predetermined amount of time at a second predetermined temperature such that intimate mixing of the elemental sulfur and the asphalt crumb mixture is achieved. |
