Fibrous additive to mineral-bitumen mixes and method for the manufacture of the additive and its application in mineral-bitumen mixes

摘要

The fibrous additive to bituminous mixes used for road pavements consists of carded textile cord from rubber products, preferably automobile tires wasted, which is removed during the grinding and processing of such products into granulate, moreover, the additive consists of fibers no longer than 30 mm and residues of rubber granulate in the amount of 40% m/m in relation to the fibrous material. The bituminous mix consisting of bitumen, or polymer-modified bitumen, mineral aggregate containing coarse, and fine fractions, and mineral filler contains the fibrous material made of carded textile cord from rubber materials in the amount of up to 4% m/m, preferably 0.2 to 3 % m/m, in relation to the mix.
