Abstract

1. Щебеночно-мастичная асфальтобетонная смесь, включающая щебень, песок из отсевов дробления, минеральный порошок, битум и композиционный материал «УНИРЕМ-001», отличающаяся тем, что дополнительно содержит волокнистую добавку и адгезионную азотсодержащую добавку при следующем соотношении компонентов, мас.%:2. Способ получения щебеночно-мастичной асфальтобетонной смеси,включающий введение в асфальтосмеситель щебеночных и песчаных фракций минеральных материалов с t=150-195°C и перемешивание, введение ненагретого минерального порошка и перемешивание, введение битума с t=110-165°C и перемешивание, введение композиционного материала «УНИРЕМ-001» и перемешивание, отличающийся тем, что после введения минерального порошка и перемешивания вводится смесь композиционного материала «УНИРЕМ-001» и волокнистой добавки в соотношении композиционный материал «УНИРЕМ-001» - 30-70% по объему, волокнистая добавка - 70-30% по объему, при этом смесь «УНИРЕМ-001» и волокнистой добавки получается после введения их раздельно в разделенный на две части приемный бункер линии гранулированных добавок и перемешивания в процессе транспортирования по винтовому конвейеру, а в битум до его подачи в асфальтосмеситель вводится и однородно распределяется в нем адгезионная азотсодержащая добавка.1. Crushed stone and mastic asphalt mixture, including crushed stone, sand from crushing screenings, mineral powder, bitumen and composite material “UNIREM-001”, characterized in that it additionally contains a fibrous additive and an adhesive nitrogen-containing additive in the following ratio of components, wt.%: 2. A method of producing crushed stone-mastic asphalt concrete mixture, comprising introducing crushed stone and sand fractions of mineral materials into the asphalt mixer with t = 150-195 ° C and mixing, introducing unheated mineral powder and mixing, introducing bitumen with t = 110-165 ° C and mixing, introducing the composite material “UNIREM-001” and mixing, characterized in that after the introduction of the mineral powder and mixing, a mixture of the composite material “UNIREM-001” and the fibrous additive in the ratio composite material “UN IREM-001 "- 30-70% by volume, fiber additive - 70-30% by volume, while the mixture" UNIREM-001 "and fiber additive is obtained after introducing them separately into a two-part receiving hopper of the granular additives and mixing line during transportation by a screw conveyor, and before it is fed into the bitumen, an adhesive nitrogen-containing additive is introduced and uniformly distributed in it.
