Abstract
Unvulcanized rubber mixture includes at least one rubber, aggregate, and at least one filler, wherein a surface of the at least one filler has been modified with a stimuli-sensitive substance. A filler for unvulcanized rubber mixtures includes a surface which has been modified with a stimuli-sensitive substance. A process for making an unvulcanized rubber mixture including at least one rubber, aggregate, and at least one filler, wherein a surface of the at least one filler has been modified with a stimuli-sensitive substance. The process includes coating a surface of at least one filler with a stimuli-sensitive substance to form at least one coated filler, and mixing the at least one coated filler with unvulcanized rubber and aggregate. A rubber product formed from an unvulcanized rubber mixture includes at least one rubber, aggregate, and at least one filler, wherein a surface of the at least one filler has been modified with a stimuli-sensitive substance. Vulcanized rubber including a rubber matrix comprising aggregate and at least one rubber, and at least one filler, wherein a surface of the at least one filler has been modified so as to form a stimuli-sensitive rubber mixture with the rubber matrix surrounding the at least one filler.
