Значительное повышение интенсивности автомобильного движения и возросшие нагрузки на ось транспортных средств на дорогах привели к тому, что асфальтобетоны не в состоянии обеспечить необходимую долговечность дорожных покрытий. Долговечность асфальтобетонных покрытий напрямую связана с качеством используемых материалов и, прежде всего, с каменными материалами, формирующими структуру асфальтобетона. Задачи обеспечения качества дорожной продукции и его контроль требуют системного подхода, что обеспечивается, прежде всего, наличием надлежащей системы оценки качества, методов и приборов для проведения испытаний свойств дорожных материалов, изделий и конструктивных слоев, в соответствии с установленными нормативными документами, показателями. В работе рассмотрены вопросы оптимизации выбора крупного заполнителя (щебня) для асфальтобетона из условия наилучшей адгезии с битумом, применяемого в дорожных организациях Владимирской области. Выполнялись лабораторные испытания каменного материала различных производителей для получения прочного, сдвигоустойчивого и трещиностойкого материала дорожных покрытий. Результаты испытаний показали, что наиболее пригодным для приготовления горячих асфальтобетонных смесей является щебень из габбро-диабаза. Приводится протокол испытаний щебня, подбор состава асфальтобетона на габбро-диабазом щебне и результаты испытаний асфальтобетона.

The significant increasing of both road traffic and loads on the vehicle axle led to unavailability of asphalt concrete to provide the necessary durability of road surfaces. The durability of road surfaces is directly related to the quality of the construction materials used and, above all, to the roadstone aggregate used to form the asphalt concrete. The quality assurance and control of road products requires a systematic approach, which is ensured primarily by having a proper quality assessment system, methods and instruments for testing the properties of road materials, products and structural layers, in accordance with the established standards, indicators. The paper considers the issues of optimizing the choice of a large aggregate (crushed stone) for asphalt concrete in terms of the best adhesion with bitumen used by road construction companies of the Vladimir region. For laboratory testing we use the roadstone aggregate by various manufacturers in order to produce a durable, shear-resistant and crack-resistant road surface material. By the experimental results, crushed gabbro-diabase crushed stone is the most suitable for the preparation of hot asphalt mixtures. The paper contains a crushed stone test report, information on gabbro-diabase crushed stone selection of asphalt concrete composition and results of asphalt concrete testing.
