Abstract
There is described a composition for use with aggregate which improves the wetting-out capabilities of bitumen, and therefore the resilience and ageing characteristics of asphalt concrete formed through admixture of the aggregate with the composition prior to addition of a bitumen binder. The composition comprises an inorganic component, polyisobutylene and an organic component comprising an elastomer such as an ethylene propylene elastomer. The inorganic component is formed principally from soda lime glass, in combination with a geopolymer. The aggregate admixture, coated aggregate and modified asphalt concrete formed therewith are also described.
Claims (22)
1. A composition comprising: 80 to 95% by weight of an inorganic component, 3 to 5% by weight of polyisobutylene; and 2 to 15% by weight of an organic component comprising elastomer polymers of alkylene or isoalkylene, but excluding polyisobutylene, wherein the combination of inorganic component, polyisobutylene and organic component sums to 100%, and wherein said inorganic component comprises: 60 to 90% by weight of soda lime glass, and 10 to 40% by weight of a geopolymer.
2. The composition as claimed in claim 1 wherein the polyisobutylene has a weight average molecular weight (MW Mn) of from 950 to 2400.
3. The composition as claimed in either one of claims 1 and 2 wherein the organic component comprises polyethylene, polypropylene, polybutene, polybutadiene or polyisoprene, polyalphaolefin, polyester, and polyacrylate and its copolymers.
4. The composition as claimed in any one of claims 1 to 3 wherein the organic component comprises a propylene elastomer.
5. The composition as claimed in any one of claims 1 to 4 wherein the organic component comprises an ethylene propylene elastomer.
6. The composition as claimed in any one of claims 1 to 5 wherein the organic component further includes a polyethylene wax.
7. The composition as claimed in any one of claims 1 to 6 wherein the organic component further includes an anti-oxidant.
8. The composition as claimed in any one of claims 1 to 7 wherein the soda lime glass comprises silicon dioxide and one or more of sodium oxide, calcium oxide, magnesium oxide and/or aluminium oxide.
9. The composition as claimed in any one of claims 1 to 8 wherein the inorganic component comprises: 60 to 90% by weight of soda lime glass, and 5 to 40% by weight of a phyllosilicate (such as kaolin) and 0 to 5% by weight of either a boron compound or a magnesium aluminium phyllosilicate.
10. The composition as claimed in any one of claims 1 to 9 wherein the inorganic component comprises: 60 to 90% by weight of soda lime glass, and 5 to 39% by weight of a phyllosilicate (such as kaolin) and 1 to 5% by weight of either a boron compound or a magnesium aluminium phyllosilicate.
11 . The composition as claimed in any one of claims 1 to 10 wherein the inorganic component comprises: 60 to 90% by weight of soda lime glass, and 5 to 37% by weight of a phyllosilicate (such as kaolin) and 3 to 5% by weight of either a boron compound or a magnesium aluminium phyllosilicate.
12. The composition as claimed in any one of claims 1 to 1 1 wherein the soda lime glass has a particle size of 300pm or less.
13. The composition as claimed in any one of claims 1 to 12 wherein the geopolymer is a kaolin.
14. An aggregate admixture, wherein the admixture comprises aggregate in combination with a composition as claimed in any one of claims 1 to 13.
15. The admixture as claimed in claim 14 wherein the composition comprises 1 to 10% by weight of the total weight of the admixture.
16. An aggregate which is at least partially coated with the composition as claimed in any one of claims 1 to 13.
17. A stone matrix asphalt concrete comprising the aggregate admixture as claimed in either one of claims 14 and 15 or the coated aggregate as claimed in claim 16, together with a bitumen binder.
18. The stone matrix asphalt concrete as claimed in claim 17, wherein the aggregate component is formed from 92 to 95% by weight of the aggregate admixture or coated aggregate and from 5 to 8% by weight of bitumen binder.
19. A method of forming a coated aggregate or a modified aggregate, wherein the composition as claimed in any one of claims 1 to 13 is admixed with aggregate.
20. The method as claimed in claim 19 wherein said aggregate is a gradated aggregate having a particle size of from 1 mm to 20mm.
21 . The method of either one of claims 19 and 20 wherein 1 to 10% by weight of the composition is admixed with the aggregate.
22. A method of forming an asphalt concrete as claimed in either one of claims 20 and 21 , said method comprising admixing at least some of the aggregate particles with the composition as claimed in any one of claims 1 to 13 to form an admixture or to form a coated aggregate, optionally adding further aggregate, and then adding a bitumen binder to form a concrete.
