Abstract

Official abstract text for this publication.

A bitumen composite includes an amine-impregnated zeolite and bitumen. Forming the bitumen composite includes combining bitumen and an amine-impregnated zeolite to yield a mixture, heating the mixture to yield the bitumen composite.

First claim

Opening claim text (preview).

What is claimed is: 1 . A bitumen composite comprising: an amine-impregnated zeolite comprising a zeolite impregnated with an amine; and bitumen. 2 . The bitumen composite of claim 1 , wherein the bitumen composite comprises about 0.1 wt % to about 5 wt % of the amine. 3 . The bitumen composite of claim 1 , wherein a weight ratio of the amine to the zeolite is up to about 1. 4 . The bitumen composite of claim 3 , wherein the weight ratio is in a range of about 0.6 to 1. 5 . The bitumen composite of claim 1 , wherein the bitumen composite comprises up to 5 wt % of the zeolite. 6 . The bitumen composite of claim 1 , wherein the amine comprises ethylenediamine. 7 . The bitumen composite of claim 1 , wherein the zeolite comprises a natural or synthetic zeolite. 8 . The bitumen composite of claim 7 , wherein the zeolite comprises a Faujasite-type zeolite. 9 . The bitumen composite of claim 1 , further comprising an aggregate. 10 . The bitumen composite of claim 9 , wherein the aggregate comprises one or more of sand, crushed stone, gravel, and rock dust. 11 . A method of forming a bitumen composite, the method comprising: combining bitumen and an amine-impregnated zeolite to yield a mixture, wherein the amine-impregnated zeolite comprises a zeolite impregnated with an amine; and heating the mixture to yield the bitumen composite. 12 . The method of claim 11 , wherein heating the mixture comprises heating the mixture to a temperature of about 100° C. to about 200° C. 13 . The method of claim 11 , wherein heating the mixture comprises heating the mixture for about 1 minute to about 100 minutes. 14 . The method of claim 11 , wherein the bitumen composite comprises about 0.1 wt % to about 5 wt % of the amine. 15 . The method of claim 11 , wherein a weight ratio of the amine to the zeolite is up to about 1. 16 . The method of claim 15 , wherein the weight ratio is in a range of about 0.6 to 1. 17 . The method of claim 11 , wherein the bitumen composite comprises up to 5 wt % of the zeolite. 18 . The method of claim 11 , wherein the amine comprises ethylenediamine. 19 . The method of claim 11 , wherein the zeolite comprises a natural or synthetic zeolite. 20 . The method of claim 19 , wherein the zeolite comprises a Faujasite-type zeolite. 21 . The method of claim 11 , further comprising combining the bitumen composite with an aggregate. 22 . The method of claim 21 , wherein the aggregate comprises one or more of sand, crushed stone, gravel, and rock dust. 23 . A composition comprising: the bitumen composite of claim 1 .
