Composition and modified aggregate for asphalt concrete
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.
