Аннотация:Привводятся результаты исследований щебеночно-мастичного асфальтобетона (ЩМА). Показано, что в качестве минерального порошка в ЩМА может применяьтся нефелиновый шлам - отход глиноземного производства ОАО "РУСАЛ Ачинск", а в качестве битумоносителя - резиновая крошка с включениями кордного волокна, полученная после дробления старых автомобильных покрышек. Разработаны составы ЩМА с применением этих отходов. Испытания показали, что полученные составы отвечают нормативным требованиям. Разработанные составы были внедрены "Красноярскавтодором" на дорогах Красноярского края.
Crushed stone-mastic asphalt concrete is a more durable material compared to traditional asphalt concrete. But for its exploitation, high-quality mineral powders and bituminous carriers are needed to prevent bitumen from flowing out of the composition. Today, the carbonate rock powders and bituminous carriers from natural cellulosic fibers are widely used. However, many Russian Federation regions, including the Krasnoyarsk Territory, are not provided with these materials, and they are also really expensive. The purpose of our work was to reduce the cost and improve the properties of crushed stone-mastic asphalt concrete. The task of the research was to develop gravel-mastic asphalt concrete compositions using the industrial waste from the Krasnoyarsk Territory. Nepheline sludge was tested which is the waste of the alumina plant in Achinsk and rubber crumb with inclusions of cord fiber of Chernogorsk in Krasnoyarsk Territory. The chemical composition and physical and mechanical properties of these wastes were studied. Gravel-mastic asphalt concrete compositions were made by using these wastes. The tests showed that the received compositions met regulatory requirements. The developed compositions were introduced by “Krasnoyarskavtodorom” on the Krasnoyarsk Territory roads. The economic effect of the waste usage is achieved through the exploitation of the local raw materials, which leads to a reduction of the transportation and energy costs.
