Abstract

Some embodiments of the present disclosure relate to a method comprising mixing at least one compatibilizer precursor with at least one polymer, so as to result in a polymer concentrate and mixing the polymer concentrate with asphalt, so as to result in a polymer modified asphalt (“PMA”). Some embodiments of the present disclosure relate to formulations comprising a compatibilizer precursor, a polymer concentrate, PMA, or any combination thereof.

Claims (32)

1 . A method comprising:

mixing at least one compatibilizer precursor with at least one polymer, so as to result in a polymer concentrate,

wherein the at least one compatibilizer precursor comprises at least one paraffinic oil, at least one petroleum extract, at least one naphthenic oil, at least one aromatic oil, at least one re-refined engine oil bottom (REOB), at least one engine oil residue (EOR), at least one re-refined heavy vacuum distillation bottom (RHVDB), at least one re-refined heavy vacuum distillation oil (RHVDO), at least one re-refined vacuum tower bottom (RVTB), at least one vacuum tower bottom (VTB), or any combination thereof; and

mixing the polymer concentrate with asphalt in a mixer to form a polymer modified asphalt (“PMA”).

2 . The method of claim 1 , wherein the at least one polymer is mixed with the at least one compatibilizer precursor in a weight ratio of the at least one polymer to the at least one compatibilizer precursor of 1:100 to 2:1.

3 . The method of claim 1 , wherein the at least one polymer is mixed with the at least one compatibilizer precursor in a weight ratio of the at least one polymer to the at least one compatibilizer precursor of 1:10 to 2:1.

4 . The method of claim 1 , wherein the at least one polymer is mixed with the at least one compatibilizer precursor in a weight ratio of the at least one polymer to the at least one compatibilizer precursor of 1:5 to 2:1.

5 . The method of claim 1 , wherein the at least one compatibilizer precursor comprises at least one resin, at least one process oil, or any combination thereof.

6 . The method of claim 1 , wherein the at least one at least one compatibilizer precursor comprises at least one aromatic oil.

7 . The method of claim 6 , wherein the at least one aromatic oil comprises HYDROLENE®.

8 . The method of claim 1 , wherein the at least one polymer comprises at least one polyolefin, oxidized polyethylene (OPE), polyethylene-polypropylene elastomer, ground tire rubber (GTR), isotactic polypropylene (IPP), atactic polypropylene (APP), styrene-butadiene-styrene (SBS) copolymer, a styrene-ethylene-butylene-styrene (SEBS) copolymer, polyvinyl butyral (PVB) or any combination thereof.

9 . The method of claim 1 , wherein the at least one polymer comprises oxidized polyethylene (OPE).

10 . The method of claim 1 , wherein the at least one polymer comprises a styrene-ethylene-butylene-styrene (SEBS) copolymer.

11 . The method of claim 1 , wherein the polymer concentrate has a softening point of 195° F. to 350° F. as measured according to ASTM D36.

12 . The method of claim 1 , wherein the polymer concentrate has a penetration point of 15 dmm to 200 dmm as measured according to ASTM D5.

13 . The method of claim 1 , wherein the asphalt has a softening point of 100° F. to 250° F. as measured according to ASTM D36.

14 . The method of claim 1 , wherein the asphalt has a penetration point of 1 dmm to 50 dmm as measured according to ASTM D5.

15 . The method of claim 1 , wherein the polymer concentrate is mixed with the asphalt in a weight ratio of the polymer concentrate to the asphalt of 1:50 to 1:1.

16 . A formulation comprising:

at least one polymer;

at least one compatibilizer precursor,

wherein the at least one compatibilizer precursor comprises at least one paraffinic oil, at least one petroleum extract, at least one naphthenic oil, at least one aromatic oil, at least one re-refined engine oil bottom (REOB), at least one engine oil residue (EOR), at least one re-refined heavy vacuum distillation bottom (RHVDB), at least one re-refined heavy vacuum distillation oil (RHVDO), at least one re-refined vacuum tower bottom (RVTB), at least one vacuum tower bottom (VTB), or any combination thereof; and

asphalt;

wherein the formulation is a polymer modified asphalt (PMA).

17 . The formulation of claim 16 , wherein the at least one polymer comprises at least one polyolefin, oxidized polyethylene (OPE), polyethylene-polypropylene elastomer, ground tire rubber (GTR), isotactic polypropylene (IPP), atactic polypropylene (APP), styrene-butadiene-styrene (SBS) copolymer, a styrene-ethylene-butylene-styrene (SEBS) copolymer, polyvinyl butyral (PVB) or any combination thereof.

18 . A polymer modified asphalt (PMA) composition comprising:

a polymer concentrate comprising:

at least one compatibilizer precursor and at least one polymer,

wherein the at least one compatibilizer precursor comprises at least one paraffinic oil, at least one petroleum extract, at least one naphthenic oil, at least one aromatic oil, at least one re-refined engine oil bottom (REOB), at least one engine oil residue (EOR), at least one re-refined heavy vacuum distillation bottom (RHVDB), at least one re-refined heavy vacuum distillation oil (RHVDO), at least one re-refined vacuum tower bottom (RVTB), at least one vacuum tower bottom (VTB), or any combination thereof; and

asphalt.

19 . The PMA composition of claim 18 , wherein the polymer concentrate is present in the composition in a weight ratio of the polymer concentrate to the asphalt of 1:50 to 1:1.

20 . The PMA composition of claim 18 , wherein the at least one polymer comprises at least one polyolefin, oxidized polyethylene (OPE), polyethylene-polypropylene elastomer, ground tire rubber (GTR), isotactic polypropylene (IPP), atactic polypropylene (APP), styrene-butadiene-styrene (SBS) copolymer, a styrene-ethylene-butylene-styrene (SEBS) copolymer, polyvinyl butyral (PVB) or any combination thereof.
